Hardening and tempering heat treatment of steel in a school workshop is normally a two stage process for example if a high carbon steel or silver steel screw driver blade has been manufactured at some point it will have to be hardened to prevent it wearing down when used on the other hand it will have to be tempered. driver blade is placed on a steel surface, such as an anvil face. On the other hand, if the red hot

The main difference between annealing hardening and tempering is that annealing is done to soften a metal or an alloy and hardening is done to increase the hardness of a metal or alloy whereas tempering is done to reduce the brittleness of quenched metal or alloy.

HARDENING AND TEMPERING. The main difference between annealing hardening and tempering is that annealing is done to soften a metal or an alloy and hardening is done to increase the hardness of a metal or alloy whereas tempering is done to reduce the brittleness of quenched metal or alloy.
