Quenching is the process of rapid cooling after heat treatment of a workpiece, while tempering is a process which involves heat treating to increase the toughness of iron-based alloys. So, the key difference between quenching and tempering is that the quenching is rapid cooling of a workpiece, whereas tempering is heat-treating a workpiece.

This involves heating the element again, but to a point far below the temperature reached in the quenching stage usually around 540 degrees Celsius. The amount of time the quenched metal is tempered is the determining factor to how much hardness is removed.See all results for this question

Can 4140 steel be welded?

AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat-treated condition, and post-weld heat treatment should be performed.
