Tempering Heat Treatment Process

Why?
Steel materials are tempered to relieve stresses induced during forming or machining and to reduce hardness developed during welding.

Process?
In steel tempering, a previously hardened part is heated to a point below a critical temperature and then cooled at a specified rate.

Benefits?
Tempered steel has increased toughness, reducing brittleness caused by machining or welding.
