H13 die steel is a hot work die steel. Otai steel 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 to more than 30 countries from Europe and American, Middle East, and Asia. our steel materials meet DIN/ ASTM/EN/JIS etc different international standards.

H13 die steel is a hot work die steel. It is formed by adding alloying elements to carbon steel. H13 die steel is the most widely used and most representative hot work die steel. It can be used for die forging hammer ,Aluminum alloy die-casting molds, hot extrusion dies, high-speed precision forging dies and forging press dies, etc. It can also be used to make important components in the aerospace industry. A client comes from Asia bought the H13 die steel from our company, in order to make the forging dies.

Due to the special variety of mold steel, and the special steel demand in the market is small (only 10% of the steel mill), steel mills are not willing to produce mass production, so some unscrupulous traders fake the real die steel, the mold steel market engage in black smoke. There are many companies selling mold steel without testing equipments, and the materials with unstable quality are directly delivered to the factory. When the factory is processing fast, it finds holes or cracks inside. At this time, the factory will blame the mill for the painful days, and the subsequent delivery will be delayed. The factory brings serious economic losses.

Special steel application expert Tan Hong Pu tells you the 8 secrets you don’t know about buying mold steel:

1. The small steel mill changes the tag of the big steel factory;

2, ordering at the big steel mill, but not according to national standards, stealing the process, saving costs

3. Intermediate frequency furnace instead of electric arc furnace production

4, electric arc furnace instead of electroslag

5. The steel mill determines that the defective material acts as a good material.

6. Play word games to ensure that the main elements meet national standards, not to mention harmful elements exceeding the standard.

7, sell universal steel, what materials you want;

8, non-standard direct sales as a national standard.

Therefore, it is 100% safe to buy materials with Otai special steel, and the export standard test also saves you 30%. Anyone who verbally says how good the quality is, no test is empty talk. Strict testing and safe use; peers do not dare to face-to-face testing, Aotai dare to face-to-face inspection for you, welcome to our company!

High-speed steel is really important in our lives. Otai steel 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 to more than 30 countries from Europe and American, Middle East, and Asia. our steel materials meet DIN/ ASTM/EN/JIS etc different international standards.

When we look at our surroundings, we will find that steel is really important in our lives. the subway, bus, elevator, Cups, knives, watches, etc, all of those things are made of steel. However, the type of steel is really very much. Although I may be a layman for steel, I am gradually learning about it.

knowledge about high-speed steel.

High-speed steel is a complex alloy steel containing carbide forming elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. It is a tool steel with high hardness, high wear resistance, and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel. It maintains high hardness even under high-speed cutting.

The carbon tool steel is unstable, and the ability to cut metal may be completely lost with temperature changes, which limits the use of carbon tool steel for cutting tools. High-speed steel, because of its good red hardness, makes up for the fatal shortcomings of carbon tool steel and can be used to make cutting tools. Because high-speed steel has good process performance and good strength and toughness. It is mainly used to manufacture complex thin-blade and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies.

To communicate with customers and enhance customers’ understanding of our company, last month our colleagues went to Asia on a business trip . We visited a company with cooperation. He mentioned that he wanted to cooperate with our company to make a paper-cutting machine. That is, high-speed steel and carbon steel or alloy steel are combined together to make full use of the cutting function of high-speed steel to achieve practical and cost-saving purposes.

The customer said that the design of the product will be given to us. Generally speaking, high-speed Steel is used directly and is not used in conjunction with other steels. I believe this cooperation will be mutually beneficial cooperation for us and our customers. Recently, One of our customers comes from Italy, purchased the  1.3243 and 1.3343 high-speed steel round bars from our company. Also, he is interested in M2 high-speed steel bars, he wants to have further cooperation with us.

It is about sorting out the keywords of the company’s various steel products. as well as the company’s advantages, benefits, and selling points. This gave us a deeper understanding of the company and a deeper understanding of the brand story of Otai. To understanding. First of all, we work together to sort out a series of product keywords related to dying steel, tool steel, alloy steel, d2 die steel, 4340 steel, 4140 steel. Everyone is very serious in order to do the keyword sorting work. Keywords, then the article will be written for the sorted keywords.

During the training break, I looked at the company’s inquiry, checked the mailbox, and saw inquiries from d2 mold steel. The customer asked about the price of the relevant d2 steel. They also asked related technical parameters and asked for the quotation. I was very pleased, and then I asked for the inquiry. Transferred to business colleagues to follow up, although the promotion is really very tedious, when the flow is turned into an inquiry, it is estimated to be the most fulfilling time.

A story about 42CrMo4 special steel

This afternoon, a steel-selling colleague brought a customer from Dubai; specifically to our company to see the 42CrMo4 special steel sheet; this company is specialized in helping equipment maintenance of Dubai  Automobile Factory; all their equipment is from Japan. This customer used to buy the 42CrMo4 sheet in the local, unfortunately，find the materials can not meet the requirements, so the customer took the steel to the inspection company, but was found to be false.

This time, this customer was afraid of being deceived. She flew to Dongguan (a city of Guangdong province) to see the 42CrMo4 material. At that time, the customers went to our warehouse and were very shocked. They saw that there are so many 42CrMo plates in our warehouse, and there is two Kind of delivery status. One is the American standard 4140 pre-hard, and the other is the national standard 42CrMo. But this customer asked how can I prove that this material is true, we immediately took out our company’s testing equipment spectrometer and immediately showed it to him. Because this customer has never seen a handheld spectrometer before. He said that your company still has such advanced testing equipment. He was very recognized for the quality of our company.

Finally, we talked a lot about the chaos in the market. He said that when he sold special steel, he stepped on the pit without paying attention. The boss couldn’t find the materials he wanted, so he bought the materials from one of the suppliers on the Internet. As a result, many materials were fake. They spent a lot of money and were fined by customers because of delaying production. He said that sometimes he felt particularly helpless. When he left, he said that this special drive to Dongguan and was too worthy. He said he will find us when he buys special steel next time.

A few days ago, the customer  M2 steel has been completed. This is a very high requirement for the tolerance of M2  steel. Once customers have also looked for different counterparts to do this M2, but because many M2 tool sheets of steel do not offer accurate tolerances. because the M2 tool steel is special high-speed steel, and M2 tool steel contains high-value alloying elements such as tungsten, molybdenum, chromium and vanadium, M2 The tool steel is more expensive than other special steels. From the production of the M2  steel to the post-processing, it must be cautious and slightly wrong. The whole batch of goods must be scrapped.

The factory was scrapped a lot because of the tolerance processing, resulting in several tons of M2 steel scrap, the cost is very expensive. Due to the very high tolerance requirements of the M2  steel, we package the M2 steel in wooden boxes for each customer in better and more comprehensive use of raw materials. Each wooden box is equipped with 2 tons of M2  steel.

the composition of M2 tool steel

Also, M2 steel also be named as wind steel or front steel, it means hardening even when cooled in the air during quenching, and it is very sharp. It is a complex alloy steel containing tungsten, molybdenum, chromium, vanadium, cobalt and other carbide forming elements. The total amount of alloying elements is about 10 to 25%. It maintains high hardness under high heat cutting (about 500 ° C) and HRC can be above 60. This is the main characteristic of high-speed steel *** – red hardness.

However, after quenching and low-temperature tempering, carbon tool steel has high hardness at room temperature, but when the temperature is higher than 200 °C, the hardness drops sharply, and the hardness at 500 °C has dropped to a similar degree to the annealing state. The ability to cut metal is completely lost, which limits the use of carbon tool steel for cutting tools. High-speed steel, because of its good red hardness, makes up for the fatal shortcomings of carbon tool steel and can be used to make cutting tools.

M2 steel is a demand by Mexico, Argentina, the United States, Germany mostly, customers are very satisfied with the quality of our company’s M2 tool steel. Singapore, Malaysia, and other trading companies also like to buy M2 steel with us, because our M2 steel delivery is fast, and the cooperation M2 tool steel suppliers are particularly numerous, the price is the most competitive in the industry and will calculate for customers At the lowest cost, we can purchase the most cost-effective M2 steel.

How to choose the M2 tool steel that is most suitable for your company?

First of all, you need to take the main products of your company. The size of the M2 steel is used by your company. Does it have a dimensional tolerance requirement for the M2 steel, and is the M2  steel black or shiny? What is the hardness requirement of M2  steel? M2 steel requires the state to be annealed or tempered? Is there a straightness requirement? Whether there are grain size requirements, whether it is required for microscopic organization, etc., all relevant technical data of steel for M2  steel. We will recommend the M2 steel that suits you best.

Today, let’s talk about the M42 high speed steel, Other Known Names are 1.3247, HS 2-10-1-8, S500, E M42, REX M42^®, Dynamax. M42 is a molybdenum series high-speed steel alloy with an additional 8 or 10 percent cobalt, it has superior red hardness and wearing resistance as compared to conventional high-speed steels. This allows for shorter cycle times in production environments due to its higher cutting speeds and from the increase in time between tool changes. M42 steel costs less when compared to those same tools made of carbide.

Recently, one of our client from Italy bought M42 steel 15tons from our company, mainly apply to high cutting tools such as drills, he is satisfied with our product.
