Hardening Process

It is described total of the hardening and tempering processes that it will be obtained to steel high toughness.

Hardening process is the heating of the steel to ostenite phase temperature (850–900°C), holding the part enough time at this temperature and hardening with cooling by water or oil or warm solution. The getting of steel part to a homogeneous structure determines the holding time it in ostenite temperature, and this time changes due to chemical combination of steel.
