Overview: 420 stainless steel, 420 stainless steel is 420 "cutting class" martensitic steel, similar to Brandt's first high-chromium stainless steel this. 420 has some wear and corrosion resistance, high hardness, its price is lower stainless steel ball in a class for the general requirements for stainless steel work environment. 420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, apparatus, instruments, means of transport, and household appliances. Used for manufacture of anti-air, steam, water and oxidizing acid corrosion of components.
