What is quenching and tempering? Quenching and tempering are processes that strengthen and harden materials like steel and other iron-based alloys. The process of quenching or quench hardening involves heating the material and then rapidly cooling it to set the components into place as quickly as possible.
What is quenched and tempered steel used for?
It contains the toughness-factor means greater resistance to wear and abrasion. For this reason, quenched and tempered steel is used in machinery and structures where greater abrasion resistance and higher yield strength such as quarrying, mining, earthmoving and construction etc are required.
What temperature is quenched and tempered?
Quenching and tempering refers to the hardening (Quenching) of materials at temperatures from 800 — 1,100 °C with a subsequent re-heating (Tempering) at temperatures from 540 — 680 °C. Hardening is a heat treatment process that comprises of austenitizing and rapid cooling.
What is the difference between tempered and quenched martensite?
As-quenched martensite is too hard and brittle for most practical uses, but it can be tempered to recover some toughness and ductility. Tempering consists of reheating the martensite to temperatures typically between 275-750°F (135–400°C) for several hours.
Why are steel tempered after quenching?
After being quenched, the metal is in a very hard state, but it’s brittle. The steel is tempered to reduce some of the hardness and increase ductility. It’s heated for a set period of time at a temperature that falls between 400° F and 1,105° F.

What is the advantage of quench hardening?
Slower and more uniform cooling of parts is possible using higher quench media temperatures as the quenching heat treatment process is performed. This process also allows for a more uniform transformation during hardening.
