What's Heat Treatment, its process and purposes ?

2017-03-20

Heat Treatment-- the secondary process after production or mid production to enhance the metal properties.

Process--the microstructure of materials are modified after heat treatment. The phase transformation influences mechanical properites, such as strength, ductility, toghness, hardness and wear-resistance.

Purpose--to increase the service life of a product by increasing its strength or hardness, prepare the material for improved manufacturability. Heat Treatment generally used to improve the metal properites, to make it togher or harder and more wear-resistant.

After heat treatment, the hardness of our forging bucket teeth is between 48-53HRC, at which state they are most wear-resistant, and service life longest. Thus decrease the replacement cost, that is most cost performant.
