Operation method: Put the steel into the carburizing medium, heat it to 900-950 degrees and keep it warm, so that the steel surface will get a carburized layer with a certain concentration and depth.

Objective: To improve the surface hardness, wear resistance and fatigue strength of steel parts, and maintain the toughness of the heart.

Application points: 1. For low carbon steel and low alloy steel parts with a carbon content of 0.15% to 0.25%, the depth of the carburized layer is generally 0.5-2.5mm; After carburizing, it must be quenched to obtain martensite on the surface in order to realize the purpose of carburizing.
