Vacuum degassing refined steel, stable quality;
Good hardenability, oil cooling quenching (less quenching cracks and deformation);
Good toughness and wear resistance, the tool is durable;
YK30 adds Mn and Cr on the basis of SK105 to improve the hardenability. Gauges, razors, files, cutting tools: tempering temperature 150~200℃;
Blanking die, stamping die, bending die, finishing die: tempering temperature 180~230℃;
Stainless steel parts chisels and woodworking cutting tools: tempering temperature 200~250℃. Datong Custom stainless steel parts number: YK30 JIS corresponding steel number: SKS93
