Application:

1. 420 grade stainless steel has certain wear resistance and corrosion resistance, high hardness, and its price is lower than that of stainless steel balls. It is suitable for working environments that generally require stainless steel.
2. Stainless steel AISI 420 is suitable for all kinds of precision machinery, bearings, electrical appliances, equipment, instruments, meters, transportation tools, household appliances, etc.
3. 420 martensitic stainless steel is also mostly used in the manufacture of parts resistant to atmospheric, water vapor, water and oxidative acid corrosion.
4. 20Cr13 stainless steel: Quenched state prefers high hardness and good corrosion resistance. For steam turbine blades.
5. 30Cr13 stainless steel: Harder than 20Cr13 after quenching, used as cutting tools, nozzles, valve seats, valves, etc.
