Quenching and tempering is a heat-treatment process for high-quality steel round bars. It is a two-stage heat treatment process consisting of Quenching and Tempering.

Stage 1 : Quenching / Hardening

The first stage consists of hardening, in which the round bar is austenitized to approximately 900°C depending on the grade and then quickly cooled. The material is water-quenched or oil quenched or solvent quenched in a quench unit.

Stage 2 : Tempering

It consists of tempering the material to obtain the desired material properties.

The material is then straightened. Material is tested to check if it meets requirement.

Quenching and tempering achieves an extremely fine-grained and homogeneous microstructure. They are also called QT bars. QT steel bars are characterized by high strength and good ductility.

We can provide you Quenched and Tempered Bars of grades such as SAE4140, etc.
