SUS420j2 cold rolled stainless steel rolls for turbine blades, mold development
SUS420j2 cold rolled stainless steel coil with thickness:1.0-3.0mm width: 200-1219mm HV160-400 Surface:2B BA
Description:
Alloy tool steel 420J2 is a martensitic stainless steel, and 420J1 higher carbon content than quenching state it has a high strength, hardness and wear resistance, corrosion resistance is somewhat less, and for mechanical performance requirements thanhigh corrosion resistance requirements of the general parts.
Applications:
Turbine blades, mold development, tool material, disposable razor blades scraping eyebrow blade, barber scissors, conventional gaskets, friction plates and metal stamping industry
