        420 Stainless Steel Bars
        420 stainless steel bars are widely used in the cutlery and tool industry for manufacturing knife blades, surgical instrument shafts, and precision tool blanks, as they achieve high hardness (up to 50 HRC after heat treatment) and excellent wear resistance. In the mold and hardware sectors, they are applied to produce mold guide pins, valve cores, and mechanical bearing shafts, benefiting from good machinability and moderate corrosion resistance against daily moisture. They also find applications in food processing equipment (for small-sized cutting components) and textile machinery (for wear-resistant rollers), ensuring durable performance in daily use and light industrial scenarios where both hardness and basic corrosion protection are required.
