Steels are high alloy heat-resistant steels and austenitic hot work die steels. After heat treatment, the steel itself has a relatively high hardness, reaching ~. This steel has high thermal strength, but poor thermal conductivity. It should be heated evenly before forging. It has large deformation resistance and is difficult to process. It is prone to cracks on the surface and inside of the steel ingot. It deforms slowly during forging, has a high stop forging temperature, and has poor welding performance. .
