Carbon steel carburized Round weld nut.

Description:

Carburizing treatment

Carburizing treatment refers to a chemical heat treatment process in which the steel is heated and kept in a carburizing medium in order to increase the carbon content of the surface layer of the steel and form a certain carbon concentration gradient.

A metal heat treatment process that changes the mechanical properties of the surface layer by heating and cooling the surface of the steel part. Surface quenching is the main content of surface heat treatment, and its purpose is to obtain a high hardness surface layer and favorable internal stress distribution to improve the wear resistance and fatigue resistance of the workpiece.

By heating and cooling the surface of the workpiece, and changing the structure of the surface, the metal heat treatment process to obtain the required performance. The surface heat treatment of steel parts can obtain a martensitic structure with high surface hardness, while retaining the toughness and plasticity of the core part and improving the comprehensive mechanical properties of the workpiece.
