420 stainless steel, 420 stainless steel is 420 "cut grade" martensitic steel, similar to Brinell's earliest stainless steel high chromium steel. 420 has a certain wear resistance and corrosion resistance, high hardness, its price is a low-grade stainless steel ball, suitable for the common requirements of stainless steel working environment. 420 stainless steel is suitable for A variety of precision machinery, bearings, electrical appliances, equipment, meters, instruments, transportation tools, household appliances, etc. Mainly used in the manufacture of parts resistant to corrosion by atmosphere, water vapor, water and oxidizing acid.
420 belongs to ferritic stainless steel, a kind of stainless steel, also known as stainless steel. 420 stainless steel is not as resistant to corrosion as 304 stainless steel. Passivation can improve its corrosion resistance after passivation.
