FULLY HARDENED ALLOY B-CLASS SCREW
Using imported alloy tool steel/high-speed steel as rawmaterials, through the overall vacuum quenching,secondary tempering heat treatment, combined with the "full hard nocalibration" processing technology, the overall hardness HRC:60~63 degrees. It makes its steel exhibit the excellent characteristics of strong wear resistance, moderate corrosion resistance and high temperature softening resistance.
