In daily life, most of our common moulds are made of steel. When using mould steel, we will find that some defects will occur, which

The mould makes us common workpiece casting tools, and the application field of the mould is very wide. What bothers us is that during the

The use of mould steel is very wide, so the working conditions of mould steel must meet the height, strength, wear resistance, and sufficient toughness,

In order to improve the wear resistance, toughness, fatigue fracture resistance, high temperature performance, cold and hot fatigue resistance and corrosion resistance of the mould

Although the mould processing and manufacturing is a complex and long process, according to the requirements, certain requirements and considerations must be met when performing

Cracks in the mould after quenching are defects in the heat treatment, which will cause the mould to be unusable. Therefore, we should take relevant
