Frequently Asked Questions
What is the difference between 420J1 and 420J2?
420J1 has lower carbon content, offering better corrosion resistance and ductility. 420J2 has higher carbon content, resulting in higher hardness and wear resistance.
Can 420 stainless steel be hardened?
Yes, 420 stainless steel can be heat treated to achieve high hardness (up to HRC 50+), making it ideal for cutting tools and blades.
Is 420 stainless steel corrosion resistant?
It has moderate corrosion resistance, suitable for general environments, but not as resistant as 304 or 316.
What industries use 420 stainless steel plates?
It is widely used in cutlery, medical tools, molds, machinery parts, and industrial components.
What surface finish is available for hot rolled plates?
Common finishes include black surface, annealed, and pickled surface.
