Heat Treatment Quenching & tempering

The purpose of quenching in heat treatment is to transform the undercooled austenite into martensite or bainite to obtain martensite or bainite structure, tempering at different temperatures to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, so as to meet the requirements of various mechanical parts and tools. 

WALKSON, specializing in different types of heat treatment process like annealing, quenching, hardening and tempering, has 2 types of quenching tanks. One is water tank with 4 agitators full drive stirring of the water when doing the quenching work, the other one is oil tank which suitable the casting and forging products have high carbon content. Our quench tank are designed by Australia melting expert which supposed to be the best quench tank in china. We use the quenching tank finish carbon steel casting, alloy steel casting, steel and alloy steel forging products. Main products include Mining Ground Engage Tools(G.E.T), Undercarriage products(tumbler, idler, track crawler), Rigging components, Lip, sheaves, dragline components(dragline walking cam, dragline walking frame), proper shaft, knee links, etc.
