Today, let’s talk about the M42 high-Speed steel, it has other known names such as 1.3247, HS 2-10-1-8, S500, E M42, REX M42.It is a molybdenum series high-speed steel alloy with an additional 8 or 10 percent cobalt. M42 steel has good wear resistance and hot hardness along with high hardness values. Furthermore, Excellent cutting performance can be achieved from tools made in M42 high speed steel.
It is widely used in metal manufacturing industries because of its superior red hardness as compared to more 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 costs less when compared to those same tools made of carbide.
An Italian customer bought 15 tons of M42 round steel from our company, used as a high-speed cutting tool, like a drill bit. Mostly, it is mainly used in high-end industries. he was satisfied with the product.
