M42 Steel | High Speed Steel (HSS) .
What is M42 steel ?
M42 steel is a molybdenum collection high-speed steel alloy with an extra 8 or 11 percent cobalt.
It is extensively utilized in steel manufacturing industries because of its advanced purple hardness in comparison to more conventional high-velocity steels.
This permits for shorter cycle instances in production environments due to its better cutting speeds and from the boom in time among tool adjustments.
M42 is also much less liable to chipping whilst used for interrupted cuts and prices much less whilst compared to those equal tools manufactured from carbide.
M42 steel high speed steel heat treating.

Quenching
Pressurized gas, or salt , warm oil . For pressurized gas, a rapid quench rate to below 1000°F (538°C) is critical to obtain the desired properties. For salt maintained at 1000-1100°F (538-593°C), equalize, then cool in still air to 150-125°F (66-51°C). For oil, quench until black, about 900°F (482°C), then cool in still air to 150-125°F (66-51°C).
