Heat Treatmentn of Steel en 东莞市

What is heat treatment?

Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material.

And what is the heat treatment of steel? In order to be made appropriate for various uses and applications, steel undergoes various procedures such as quenching, tempering, and annealing. Those procedures of heat treatment change the microstructure, hardness, and tensile strength of steel.

What are the various classifications of heat treatment for steel?

1.Overall Heat Treatment

This heat treatment process heats the workpiece as a whole and then cools it at an appropriate rate to obtain the required metallographic structure to change its overall mechanical properties.

2.Surface Heat Treatment

This process only heats the surface of the workpiece to change the mechanical properties of the surface.

3.Chemical Heat Treatment

This metal heat treatment process is able to change the chemical composition, structure and properties of the workpiece surface.

Comparison Table of Heat Treatment Hardness and Tensile Strength

The hardness and tensile strength poses an important parameters as regards the heat treatment of steel, so that various types of steel can be produced, depending on their future use.

If you want to find the tensile strength of steel that is equivalent to their hardness in China Standard, please go to the following table depicting the hardness to tensile strength conversion chart (GB/T 1172-1999).To learn more about , please read our website or send us ([email protected]) your requirements to achieve high-quality and reliable products.
