Quenching and Tempering Guide: Harden then Toughen Steel

Quenching and Tempering Guide: Harden then Toughen Steel

Short answer: Quenching and tempering austenitizes steel, quenches it to hard martensite and tempers it to recover toughness, the core route for shafts and tools arranged via our Heat Treatment Supplier page and the grade choice in our Tool Steel Buyers Guide.

Austenitize and Quench

Heating to 850 to 900 C then fast cooling locks a hard martensitic structure, with the steel basis in our Carbon Steel Supplier and the property view in our Hardness and Tensile Guide.

Tempering for Toughness

A 200 to 650 C temper trades a little hardness for ductility and dimensional stability; double tempering improves consistency for critical parts, arranged via our Heat Treatment Supplier page.

Applications and Quality

Shafts, tools and structural fittings rely on quench and temper; verify with our Quality Inspection Guide and documents per our Mill Test Certificate Guide.
