Stainless steel theoretical weight formula:
Weight (kg) = thickness (mm) × width (mm) x length (mm) × density values
Stainless steel gravity:
Chromium stainless take 7.75 ton / M3
Chrome-nickel stainless steel take 7.93 ton / M3
Iron take 7.87 ton / M3
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
