Hardening & Tempering

Tough hardening heat the details to one of the steel grade specified temperature and then cooled in oil.

The basic carbon content in tough hardening steels is higher than in case hardening steel. Hardness is obtained through the entire part dependent on the grade and dimension. A subsequent tempering, typically 500-650 degrees provides a good combination of hardness and toughness.
