Otai Steel  foreign sales department completed 2019 annual  sales target in November. At the same time, Domestic sales team also created the highest performance in November, especially cash orders value exceeded 100,0000. Both foreign sales team and domestic sales department organized a Winter Picnic together in Folly lake.

The winter picnic of Otai steel sales team

Otai Special steel  HR department prepared the menu according to our feedback of food in advance, then they arranged ingredients and sticks. We drove to Folly Lake Lodge on a Friday afternoon and started our winter picnic .

This is a lively & relaxing banquet. The farm is beautiful, just the sunshine, the breeze not dry, flowers are blooming . We are smile, and really want to stay here all the day ,andlose track of the minutes .

After HR communicated with the owner of farm, everyone worked together to sharpen our skill, washing vegetables, cutting food material, processing seafood, preparing cookware, and preparing sauces and so on  .

I can’t cooking except waitting .

As you know, everyone can know eating well, but not means all of them know how to cooking . Just like the Otai steel sales team know how to sell the alloy steel, carbon steel ,Tooling steel . They know what is 1.2311 ,how about the hardness of 1.2311 after heat treatment . However, it not means each sales know how to handle the steel cutting machine , how to use the Chemical composition test machine ,and how to do the steel UT test . Otai’s QC director know to handle the QC process well, but he don’t know how to cook the beef . Our QC know the hardness of tooling steel well, and also know the temperature of heat treatment well ,but he don’t know how to control the temperature & time for cooking .

When the cooking process starting , we suddenly found that our purchasing manager and sales manager are an good chef .For me ,I can not do more things for cooking except waitting to eat. But for Otai’s Chef , all the food material being different delicious food after cooking by their hand .

It is a little pity that we did not have a group photo finanlly because the sunshine goes down so fast .

Now matter what ,Dec.,12, 2019 . It is the sweet-moment belong to Otai steel team .

Material DC53  is a high-strength, high-toughness cold-work die steel, and the alloy composition is Cr8Mo2VSi. It has a medium carbon content, effectively avoiding the carbide accumulation of high-carbon high-chromium cold-working die steel.

Generally, the cryogenic treatment can be omitted and it can be maintained under strong hardness Higher toughness. The material DC53 overcomes the weakness of SKD11’s insufficient high temperature tempering hardness and toughness, and will completely replace SKD11 in general and precision molds.

Material DC53, the content of disclosed the alloy components, the manufacturers are not much different. But due to different alloy elements, steelmaking equipment, purification processes, forging processes and heat treatment processes. The final abrasion resistance and chipping resistance are very different. And the service life is very different, maybe two or three times. There are 4 levels of DC53 on the domestic market.
1) “National Standard” DC53 from scrap steel refurbishment;
2) “EAF” DC53 from scrap steel refurbishment;
3) National standard EAF DC53;
4) National standard ESR DC53,

Can material DC53 be used for stainless steel stamping die punch? Stainless steel stamping die steel, someone has used Cr12MoV, SKD11, D2, SKH-51 … and so on. All encountered cracking problems. DC53 die steel is the preferred die steel for stainless steel stamping dies. Because of the anti-cracking performance of DC53 die steel, it is the better steel in cold work die steel. Of course, DC53, which has poor purity and poor heat treatment, is also easily cracked. This also makes many people think that this material stamped stainless steel is also easy to crack. In fact no matter from the economic point or the wear resistance, comprehensive consideration, DC53 for stamping stainless steel is an ideal choice. The key is to choose material DC53 with high purity and good heat treatment process.

In particular, the Chinese domestic market is a mixed bag. People who do not understand this market are more likely to step on the pit. So that is why most overseas customers would like to choose from OTAI Special steel, as OTAI is with over 20 years’ pre-sales and after-sales special steel, we help distributors and end users to avoid all possible swindle and cheat.OTAI undertakes every order to end and solve customer’s problem without any hesitate on responsibility.

AISI H13 belongs to hot work mold steel, which is mainly used for die-casting mold, extrusion mold, wear-resistant plastic mold.

What is the AISI H13? The customer who produced the die-casting mold asked me that he had previously purchased AISI H13 from other supplier to produce aluminum alloy die-casting molds, and sometimes cracks occurred at 3000 molds, and 20,000 cracks were scrapped. And what happened on the H13? Where it should be applied on?

The huge price difference range on AISI H13 mold steel makes the purchasers confusion on the price and quality in such mixed market. How to distinguish the H13 mold steel from the different quality grade?
1) Non-standard H13 mold steel made by the small private company
2) National standard H13 die steel made by the small private company
3) ESR H13 mold steel made by the small private company
4) National standard H13 die steel
5) ESR H13 mold steel
6) ESR + ultra-refined H13 mold steel;
7) Atmosphere protection ESR H13 mold steel;

Steel alloys made from iron ore steel have less impurities. Advanced steelmaking equipment can effectively remove impurities. The steelmaking process has many steps and rigorous, which can ensure the stability of the mold steel quality. The steel mills that can meet these conditions are all large state-owned steel mills. The corresponding AISI H13 tool steel grades are on grade 4, 5, 6, and 7. These grades quality mold steel has high price, stable quality and long mold life.

Consequently, it is extremely important for selecting the most reliable supplier instead of focusing on the price. Our OTAI is very proud on this special steel field. As we are with the open and sincere attitudes on the cooperation. We provide the obtainable, affordable and the most important- reliable tool steel for our dear customers everywhere. That is why we got the firm and loyal trust from all the customers.

2019 Carbon steel price Q3 ,2019

We talked about the  price info in article part one of carbon steel price Q1 &Q2 . and we will continue the topic for Q3 2019 .

On the whole ,the prce in Q3 &Q4  keep going down 6.5 % from 636 usd at the July down to 575 USD on Sept.,2019 .

Carbon steel price of C45 hot rolled plate (Q3-2019)

In the part one article, we learned about Carbon steel price of  Q1 and Q2 ,2019.

In the first half of the year, The carbon steel price continued to increase slowly. For example, the price of carbon steel C45 (1045 )  ,which it is increased from 585USD from January to 636USD in June.

Now,let us know some information of  Q3 carbon steel price .

The following table is the price record of carbon steel (C45 plate):

Q3 Carbon steel price ：

C45 carbon steel plate :hot rolled,black surface , Thickness : 15-90mm Length: 6000-9000mm Width :2000-2300 mm

According to the Graph and tables, we found that the price of carbon steel continued to decline duing  Q3 quarter (The rate of  price go down  6.5%).

The Reason of Carbon Steel Price go down during Q3 .

The main reason for the decline in prices : the sufficient supply of the market.
Carbon steel experienced a shortage of output in the first quarter, and kept strong demand in the second quarter. In Q3,  Steel mills releasae the msaa inventory to stock market. The increase in inventory quantity is greater than the actual demand, and prices have started to decline.

The annual environmental protection inspections and steel plant equipment overhauls were successfully completed. The external factors that affect the stable production capacity of steel plants have been reduced. The production capacity of steel plants in the entire market has a stable and benign production expectation.

Relative to the decline in the US dollar price, there is another influential factor: the increase in the US dollar / renminbi exchange rate, which has caused the US dollar price of carbon steel to fall by 2-3 USD / Ton year-on-year.

A2 Steel,How to get the real A2 Steel from China?

A2 Steel

A few days ago, a customer who always bought 42CrMo form our company,the boss is specialized in for automotive molds, he asked some question about the mold steel of A2 Steel.During the conversation, I found that the customer did not know this material at all, he only notice that the foreign customers designated A2 Steel, and he was very cautious. He also asked a lot of mold steel stockist. Some of them sold mold steel at very high prices, and some of them did n’t know what is it. Before, he bought 42CrMo steel from other suppliers, the price of that fake material was also 30% higher than us.OTAI Special Steel Company sold 42CrMo without any quality problems,so he trust our company more since he work with us, and once again asked us about the situation of it.we told customer that you asked the right person this time. We are very familiar foreign mold steel standards,and you will never come to grief.

We explained to customer that because A2 Steel is the American standard mold steel, our country does not completely correspond to mold steel,if it’s good for him,we could offer some suggestion of mold steel which could be replaced.

The steel you got from others before was fake . At present, there are very few manufacturers in China, they are able to produce A2 Steel ,and the standards according to American standards. Only a few of my export companies have customized this mold steel,they according to the American standard A2 Steel standards, so those who you asked before,which sell molds. It ‘s made sense that, most of the company offered e a random quote to you. After hearing it,our customer realized why he got so much trouble of it before. Finally, the customer were so kind,and said he wish he could knew us earlier, asked their to purchaser to give A2 Steel to us.

Since being affected by flying swine fever, the price of pork in China is still very high. Interestingly, the price of pork can be compared with high speed steel, May even be more expensive than high speed steel price.

Otaisteel is a stable and reliable supplier for fortune 500 companies at home and abroad, such as Thyssenkrupp, china north industries group corporation limited. Otai exports various tool steel and alloy steel ,to more than 30 countries from Europe and American, Middle East, and Asia.

Since being affected by flying swine fever, the price of pork in China is still very high.

Interestingly, the price of pork can be compared with high speed steel, May even be more expensive than high speed steel price. The reduction of Chinese pigs also affects other countries. China pork crisis prompts German sausage fears，a sharp drop in Chinese pork production has prompted Germany’s meat industry, to warn of possible shortages at home, with price rises being passed on to the country’s sausage connoisseurs.

The Federal Meat Industry Association (BVDF) has sounded a “schnitzel alarm”, as the spread of the deadly African swine fever,it  has seen half of China’s pig population slaughtered ,and triggered a bidding war among meat importers worldwide, according to the Bild tabloid.

The BVDF says Chinese companies are also buying up large amounts of meat abroad to make up for shortfalls at home, and this is “adding up to significant demand on the world pork market”.China says it will also release more pork from its central reserve, in a bid to keep prices in the shops manageable ahead of the Lunar New Year next month, but the BVDF says German consumers will not be so lucky. African swine fever has spread throughout China, which accounts for almost half of all pork produced worldwide, and market analyst Tim Koch,he told Bild the epidemic will have a “knock-on effect on global prices for years to come”. It seems that the price of high-speed steel is not expensive.

The 4340 chromoly steel has high strength, high toughness and good hardenability, it is used to manufacture important quenched and tempered parts.

4340 chromoly steel has stability against overheating, but has high white point sensitivity, tempering brittleness, and poor weldability of steel. It needs high temperature preheating before welding and stress relief treatment after welding. Generally used in the quenched and tempered state, it can also be used as ultra high strength steel after low temperature tempering or isothermal quenching.

4340 chromoly steel is used to manufacture important quenched and tempered parts. That require good toughness, high strength and large size, such as heavy-duty shafts. It could bear high loads, steam turbine shafts and blades with a diameter greater than 250MM. It can also be used for rotor shafts and blades with operating temperatures exceeding 400 degrees. In addition, it can also be used to manufacture important parts with special performance requirements after nitriding treatment. Heat treatment specifications: quenching at 850 ° C, oil cooling; tempering at 600 ° C, water cooling, oil cooling.

Few days ago, one customer asked me what material 4340 chromoly steel is. I explained to him that it belongs to the following CrNiMo series steel of the American Standards Association. It is mainly used in petroleum equipment. Above, the material is basically similar to the 40CrNiMo GB series of our national standard, but there are differences in composition. The main difference is in Ni. In China, many unscrupulous counterparts use 40CrNiMo instead of 4340 chromoly steel. From the points of standards, it is not workable to do like this. That is because 4340 chromoly steel is completely different in composition from 40CrNiMo. In addition, it is mainly used for petroleum equipment. If there is a problem with the material, it will cause great losses to the company.

Therefore, if you are purchasing such steel material, it is necessary to find the professional and reliable supplier. Our OTAI specializes in exporting special steel to more than 30 countries in the world. We have rich and expert on this special steel field. The world ’s top 500 steel companies, also purchased the special steel from us.
