SD370/4Cr5Mo2V
The steel is a high performance Cr-Mo-V hot work die steel with good resistance to cracking, cracking,4Cr5Mo2V steel thermal wear and plastic deformation. The protective atmosphere electroslag remelting technology is used t o further improve the purity and homogeneity. In addition, with the continuous improvement of heat treat ment and thermal processing technology, the toughness of the material has also been raised to a new level.

Application
1. In die casting and hot forging applications, thermal cracking is one of the most common failure mechanisms, and the excellent performance of SD370 provides better resistance to thermal cracking .
2. As we all know, improving the hardness helps to enhance the anti-cracking ability, SD370 with its excellent toughness and hardenability, in the overall cracking is not the main consideration, by increasing the hardness of 2HRC can further improve the anti-cracking performance, so it can significantly extend the service life of the mold, obtain better economic benefits.
