High strength SUS420j1 martensitic Cold Rolled Steel Strip for mold development
SUS420j1 cold rolled stainless steel strip with thickness:0.3-1.0mm(+-0.01mm) width: 20-600mm HV160-400 Surface:2B BA
Description:
Alloy tool steel 420J1 is a martensitic stainless steel, quenched state, it has a high carbon, high strength, hardness and wear resistance, corrosion resistance is somewhat less for high mechanical performance requirements, corrosion resistancerequires the general some parts.
Applications:
Turbine blades, mold development, tool material, conventional gaskets, friction plate metal stamping industry.
