Difference between hardening and tempering
WebJan 29, 2024 · The main difference between tempering and hardening is that tempering improves the ductility of steel while hardening increases its hardness. Hardening makes the steel more brittle, and … WebThe key difference between quenching and tempering is that the quenching is rapid cooling of a workpiece, whereas tempering is heat-treating a workpiece. Quenching and tempering are important processes that are used to strengthen and harden materials like steel and other iron-based alloys.
