  • GOST X12M Details

    GOST standard material X12M belongs to the Russia, from the steel to the finished product, we have the perfect technology and many years of accumulation of experience, we can now produce products include steel coil, sheet, plate,round bar, square steel, steel wire, steel pipe, forgings, other...

    X12M Application:Cold work die steel, steel hardenability, quenching tempering hardness, wear resistance, strength are higher than the Cr12.Shape is complex,
