What is the heat treatment of CR1100/1470QP quenched ductile steel?

The heat treatment of CR1100/1470QP quenched ductile steel includes two processes of quenching and tempering.

Quenching treatment: heating the steel above the critical temperature, and then rapidly cooling to room temperature. This process changes the structure of the steel, giving it high hardness and strength.

Tempering treatment: reheat the quenched steel to a certain temperature, and then cool to room temperature. The process restores the ductility and toughness of the steel, increasing its plasticity and toughness.

Specifically, the heat treatment process of CR1100/1470QP quenched ductile steel is as follows:

Heating: Heating the steel above the critical temperature (usually 800-900°C) and keeping it for a certain period of time to ensure uniform heating of the steel.

Quenching: Rapidly cool the steel to room temperature. The quenching medium can be water, oil or air, etc. Different mediums have influence on the quenching effect.

Tempering: Heat the quenched steel to a certain temperature (usually 500-700°C), keep it for a certain period of time, and then cool it to room temperature.

Finished product treatment: Surface treatment such as grinding and polishing is carried out on the tempered steel to obtain the final finished product.
