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.
