CORE DEFINITION

Quenching, commonly known as dipping fire (English: Quenching), is a heat treatment process for metals and glass. It involves heating alloy products or glass to a certain temperature and then rapidly cooling them in mineral-containing water, oil, or air, generally to increase the hardness and strength of the alloy.

Metal heat treatment: after heating to the critical temperature, rapid cooling (water/oil/air) transforms the structure into martensite, significantly increasing hardness and strength, but accompanied by brittleness and internal stress, often requiring tempering to adjust.
