420 Stainless Steel Bar

6-40mm diameter, HRC50-55, kitchen knife edge

420J2 stainless steel bar (06Cr13) is a martensitic stainless steel that can be hardened through heat treatment. With moderate carbon content, it combines good hardness and wear resistance with corrosion resistance in weakly corrosive environments.

  • High Hardness & Wear Resistance

    Quenched hardness HRC 50–55, edge retention superior to 410 stainless steel.

  • Better Corrosion Resistance than Tool Steel

    12–14% Cr content offers better corrosion resistance than carbon tool steel in humid environments.

  • Stable Heat Treatment Performance

    Strength and toughness can be adjusted via quenching (950–1000℃ oil) + tempering (200–300℃).
