Quick Details
 

1: JIS SACM645 steel introduction

      SACM645 is nitrided steel, which is a Japanese grade alloy steel and the executive standard is: JIS G4053-2008. SACM645 alloy structural steel has high surface hardness, wear resistance and fatigue strength, good heat resistance and corrosion, and low hardenability.
