It is another high-grade steel from Takefu Steel Ltd. It has fewer carbide-forming additives than VG-10 with a similar high proportion of chromium and carbon. The content of these elements is higher than in the average stainless steels. With a precisely designed composition, the crystallization of eutectic carbides in VG steels is specially delayed in order to obtain their most uniform structure and thus increase the hardness of the steel. The steel has been developed for high-quality cutting tools. After hardening, this type of steel reaches a hardness of about 60 HRC, high hardness guarantees good sharpness. It is characterized by high resistance to corrosion, as well as wear and cracking.
Composition:
- Carbon: 0,7-0,8 %
