OTAI company specializes in providing AISI 1045 carbon steel

OTAI Company specializes in providing AISI 1045 carbon steel. AISI 1045 carbon steel is exported in large quantities in China, mainly due to the large production volume of AISI 1045 carbon steel, affordable prices, short delivery times, and large stocks of AISI 1045 carbon steel on the market. The AISI 1045 carbon steel sold by OTAI Company is generally black-skinned and hot-rolled, and it can be delivered to the same day, and it will be issued within 24 hours.

AISI 1045 carbon steel can also be called C45, S45C, 1.1191 and other grades. The grades of steel are similar to our license plates. Steel grades in most countries are composed of numbers and letters. AISI 1045 is composed of 4 numbers plus the country. Speaking of the AISI 1045 brand, I am particularly impressed because the first product I sold in the special steel industry was AISI 1045 carbon steel.

AISI 1045 carbon steel Because his price and inventory are more, as a novice, he can only try to sell it. Fortunately, my first customer asked for a cabinet of AISI 1045 round steel. Therefore, every time I see AISI 1045, I am particularly happy, because I automatically default to AISI 1045, I love 1045, and an order will come soon. Hahaha ~ Gradually I found that I really fell in love with the AISI1045 steel type, because the other one was called S45C, which happened to be the choreography of my community. Every time I bought AISI 1045, I felt happy, because I Can go home to sleep.

AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4140. Otai Special Steel provide AISI 4140 plate and round bar in any size always .

How is AISI 4140 Steel Made?
AISI 4140 is made by placing iron, carbon, and other alloying elements into an electric furnace or oxygen furnace. The major alloying elements added to AISI 4140 are:

Chromium
Manganese
Molybdenum
Once the iron, carbon, and other alloying elements have been mixed together in liquid form, it is allowed to cool. The steel may then be annealed; possibly several times.

After the annealing is complete, the steel is heated to a molten phase again so that it can be poured into the desired form and can either be hot worked or cold worked through rollers or other tools to reach the desired thickness. Of course, there are other special operations that can be added to this to reduce mill scale or improve mechanical properties.
Mechanical Properties of 4140 Steel
AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel. The additions of chromium and molybdenum are why AISI 4140 is considered a “chromoly” steel.

There are several important mechanical properties of AISI 4140, including:

Tensile Strength: AISI 4140 steel typically has a target ultimate tensile strength of around 95,000 psi.
Toughness
Ductility
Hardenability
Chemical Properties
The table below highlights the chemical composition of AISI 4140:

C Cr Mn Si Mo S P Fe
0.38-.43% 0.80-1.10% 0.75-1.0% 0.15-0.30% 0.15-0.25% 0.040% max 0.035% max Balance
The addition of chromium and molybdenum promotes corrosion resistance. The molybdenum can be particularly useful when trying to resist corrosion due to chlorides. The manganese in AISI 4140 is used to increase hardenability and as a deoxidizer. In alloy steels, manganese can also combine with sulfur to improve machinability and make the carburizing process more effective.

Chinese Carbon steel price in 2019, we made a graph of cabon steel price (C45 /S50C ) according to the price record of hot rolled carbon steel plate price from Jan-2019 until Nov.,we can found the info from graph that Chinese carbon steel price goes up and down between 636 -551 USD /TON .

2019 Carbon steel price record :

According to the graph of C45/S50C hot rolled carbon steel price  ,we can know the follow info :

In 2019 ,C45/S50C  steel price goes up and down between 636 and 551 USD per ton  .

In the Q1,2019 ,Carbon steel price kept going up .EXW price from 590 USD per ton up to 619 USD per ton on March .

In the Q2,2019 ,Carbon steel increased at EXW 637USD per ton on April ,and during May until June ,the price stable at 637 USD per ton .

In the Q3,2019 ,Carbon steel price continues fall from 637 USD to584 USD per ton .

In  the Q4,2019,Carbon steel price price kept going down 551 USD per ton ,the price hit the bottom in 2019 .and price began to rebound in Novenber until now .

The reason of carbon steel price go up during Q1 & Q2:

1. The amount of social funds is abundant, and the ferrous metal (CARBON STEEL) has attracted so much attention from market.

2.The inventory quantity of carbon steel at the market on Q1 is smaler than before ,all the manufacturer & Stockist & Distributor sell out their inventory for cash before Chinese new year 2019 .

3. Society expects the demand for construction sites will better during Q2 , and many stockist stock up a lot ,and waiting to sell by better price in Q2

4. A new round of environmental protection policies announced at the end of 2018 is being implemented, and market expectations are beginning to change.

We will continue our discussion of  Q3&Q4  carbon steel price  information next blog .

1.2344 ESR steel

Some friends asked me that any kind of steel would be same as 1.2344 ESR steel ,I thought H13 steel would be almost same as 1.2344 ESR steel

1.2344 ESR steel

Some friends asked me that any kind of steel would be same as 1.2344 ESR steel ,I thought H13 steel would be almost same as 1.2344 ESR steel,I also discussed with some heat treatment factories engineers,they told me that both 1.2344 ESR steel and H13 steel processing of heat treatment are also almost same.For this kind of understanding,what I have to say is:don’t deem anything as our limited understanding,because of the “almost same”,it made us be disadvantage fooled many times,but we were never able to found the reason of been disadvantage fooled,though 1.2344 ESR steel and H13 steel are both belong to the hot work tool steel,but because different purification processes,different forging processes,different annealing processes,different test standard,the die steel will obtain difference result of the high temperature resistance、softening properties、wear resistance、crack resistance、toughness.

D2 steel can be used in: stamping or forming dies, punches, forming rolls, knives, scissors, cutting machines, etc.

About D2 die steel

D2 die steel is an air quenched, high carbon, high chromium tool steel. It has high abrasion resistance and abrasion resistance. After heat treatment, the hardness can reach 55-62HRC, and it can be processed in the annealed state. D2 die steel hardly deforms when properly hardened. The high chromium content of D2 gives it mild corrosion resistance under hardened conditions.D2 die steel first appeared during World War II and belongs to the non-stainless steel category, semi-stainless steel tool steel. Today, D2 is very popular with tool manufacturers, knife-makers and tool factories, and almost every tool manufacturer uses D2.

D2 die steel is sometimes called “semi-stainless steel”. It has a fairly high chromium content (12%), but this number is not enough to classify it as stainless steel. However, it is more resistant to staining than some other carbon steels and has excellent wear resistance. D2 is much stronger than high-quality stainless steel such as ATS-34, but not as strong as other non-stainless steels mentioned here. Good abrasion resistance, almost no rust, and good toughness. These combined make D2 an ideal choice for a variety of tools.

Our OTAI exported this D2(1.2379/X12MF) steel material to most of Knives manufacturers end buyer so far, and got the firm trust from them. Our company has maintained no quality incident complaints for 8 years continuously, and the customers repeat order rate is exceeds 85%. As what our company goal showed, we undertakes that as a crucial company strategy… Taking on an open, transparent and sincere attitude, we are willing to work with all customers and partners to jointly supply top quality tool steel everywhere.”
Therefore, based on this, OTAI supply the steel materials to more than 30 countries all over the world.

The different between DC53 vs SKH-9

DC53 vs SKH-9

We can summary 4 points of different of DC53 vs SKH-9.

No.1.There is 2 Hrc between between DC53 vs SKH-9,The hardness of DC53 hardness should be 60-62HRC,and the hardness of SKH-9 hardness would be 62-64HRC.

No.2 The different of alloy chemical composition，DC53 alloy composition is Ce8Mo2Vsi，but SKH-9 alloy composition is W6Mo5Cr4V2,Different alloy chemical composition will offer different performance of resistance.the resistance of SKH-9 is better than DC53.

No.3 The performance of crack resistance,In cold work tool steel,DC53 is a good choice for crack resistance,and the performance of crack resistance of DC53 is better than SKH-9.

No.4 The price different of DC53 vs SKH-9,SKH-9 price is higher than DC53 2-3 times.

If you wanna know more about DC53,please click DC53,or see as below:

DC53 cold work die steel
(1) Machinability and good abrasiveness.
The machinability and the abrasiveness are superior to those of the SKD11, so the processing tool has a long life and the number of processing hours is relatively low.
(2) Advantages of heat treatment
Quench hardening is higher than SKD11, so it can improve the defects of insufficient hardness during vacuum heat treatment.
(3) Advantages of online cutting processing
High-temperature tempering can reduce the residual stress and eliminate the residual Worthfield iron, which can prevent the cracking and deformation of the wire cutting process.
(4) Advantages in surface hardening treatment
The surface hardness after surface hardening is higher than that of SKD11, so the mold performance can be improved.
(5) Advantages in repairing welding operations
Since the preheating and post-heating temperatures are lower than SKD11, the repair welding operation is relatively simple.

In the past 2 month,Chinese steel price kept going down ,and it came to an end temporarily by the end of November.A total of 13 commodities in the rise and fall list of commodity prices in November 2019 saw a month-on-month rise in the steel sector, of which 3 rose more than 5%, accounting for 15.8% of the monitored commodities.

Chinese Steel Price Information：

A total of 13 commodities in the rise and fall list of Chinese steel prices in November 2019 . There is  3 rose more than 5%, accounting for 15.8% of the monitored commodities. The top 3 commodities are re-bar (10.15%), wire (6.32%) and hot rolled coil (5.57%). There were 6 kinds of commodities that declined on a month-on-month basis, 2 kinds of commodities that dropped more than 5%, accounting for 10.5% of the monitored commodities in this sector. The decline of the top 3 products are manganese silicon (-6.53%), stainless steel (-6.22%), stainless steel plate (-3.36%). Both rose or fell 0.9 per cent this month.

The Chinese Steel price of steel hot rolled plate

Domestic plate rolling  prices rose slightly in November. Common middle board (material: Q235B; Specification: 20) the price at the beginning of the month is 3642 RMB/TON, and the price at the end of the month is 3673 RMB/TON, it is increased about 0.85% from the beginning of Nov.2019 .

The reason of Chinese Steel Price in rising on Nov. 2019

• Favorable policies and loose capital lead to Cinese steel price in rised on Nov. 2019 .

  Stable investment and shortcomings have begun to accelerate in the end of year, especially in terms of cracking down on funding sources. Chinese steel price goes up as the stable investment being increased . Recently, a number of heavy new policies have been implemented: 2020. New special debt quotas have been released in advance of 1 trillion RMB, fixed asset investment projects, and new capital management regulations have also been officially issued.

  

• Demand exceeds expectations, “supply and demand mismatch”

  In November, the domestic steel market demand exceeded expectations,and it is one of the price of Chinese steel price goes up . In the warm winter environment, the downstream operating rate remains high, and the demand for construction materials continues to rise. Also shipments have increased from the same period of previous years. On the other hand, traders are expected to be cautious at one time, and “de-stocking” efforts are too large. And social inventory continues under decline, while the leading steel mills have controlled the pace of delivery.  The process of “going north to the south” has been unsuccessful, resulting in a significant supply-side gap. Boosted by favorable real estate data, black futures rebounded strongly, eventually triggering a deeper market

• Forecast

  In November, the domestic construction steel market ushered in a rebound. The fundamental reason is that the initial market was collectively bearish, social stocks were at a low level, and demand was released more than expected, eventually forming a higher price under the mismatch between supply and demand.as thedemand increase ,and the market supply can not follow with the demand’s increase, Chinese steel price going up in short time . At present, the market prices in many places have reached annual highs. As the contradiction between supply and demand has eased, there has been resistance to rising prices.

EN19 steel is alloy structural steel. It is the most widely used high-strength steel in the automotive field. It applys on the gears and engine structures, crankshafts, knuckles, connecting rods, main shafts, intermediate gears.

OTAI has our own Chemical Spectrometer for testing EN19 chemical composition

OTAI have Chemical Spectrometer for testing the EN19 chemical composition, Ultrasonic Tester and hardness tester. OTAI supply the one stop solution for the steel material. We have our own warehouse, our machine equipment: CNC flame cutting machine, Horizontal Saw and Vertical saw cutting machine, Grinding machine and Milling machine.

What is the EN grades steel material? The EN range of steel specification was first introduced in 1941 as the War Emergency, British Standard Schedule BS970. With the assistance of the Technical Advisory Committee of the Special & Alloy Steels Committee the British Standards Institute published 58 specifications (EN1 to EN58). These steels covered the different types including carbon steels, alloy steels, case hardening steels, spring steels and stainless steels. The grades were arranged sequentially according to the chemical composition, starting with low carbon grades EN1, EN2 and EN3 working up to stainless steel grades EN56, EN57 and EN58.

EN19 chemical composition is as following:

C: 0.36-0.44; Si: 0.15-0.35; Mn: 0.70-1.00; P: ≤0.040; S: ≤0.050; Cr: 0.90-1.20; Mo: 0.25-0.35.

For the equivalent material close to EN19 chemical composition, there are GB 42CrMo, DIN 42CrMo4, AISI 4140, JIS SCM440.

OTAI provided EN19 steel is produced by the only one set of imported steelmaking equipment in China. And our OTAI survive for the honest and quality, that is why we are professional on this special steel field for more than 20years. We exported the special steel to more than 30 countries all over the world, and they are passed the standard of America, Germany and Japan.
