420 Stainless Steel Plate

420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc.It is widely used in the manufacture of components resistant to corrosion of atmosphere, water vapor, water and oxidizing acid.420 stainless steel under quenching state of high hardness, good corrosion resistance, mostly used for cutting tools, is "no grade" martensitic steel, also used for surgical cutting tools, similar to the Brinell high chromium steel this earliest stainless steel, also used as turbine blades, etc., a wide range of applications.
