Features

• Hardenability is good. It hardens by air cooling. (Because it is air-cooled, there is little concern about cracking.)
• Heat treatment deformation is small. (Very small roasting, suitable for molds requiring precision.)
• The hardenability is good, and even for large products, the unevenness of hardness is small, and air quenching is possible.
• Wear resistance is better than SKS3.
• It has good hardenability and is suitable for vacuum heat treatment.
