3)Hardness:high Cr:58-65HRC

low Cr:45-52HRC

4)process

Good material→chemical composition analysis of material→precise control of the melting and casting→Testing before casting in order to confire of elements→Casting in molds→The first product inspection→Polishing balls→Visual inspection→Automatic oil quenching→Tempering→Test chrome,C,HRC,and impact value→Stocking
