420 stainless steel plate belongs to martensitic stainless steel, which has certain wear resistance and corrosion resistance, high hardness, and the price is lower than other stainless steel characteristics. 420 stainless steel sheet is suitable for all kinds of precision machinery, bearings, electrical appliances, equipment, instruments, meters, vehicles, household appliances, etc. 420 stainless steel is also mostly used in the manufacture of parts resistant to atmospheric, water vapor, water and oxidative acid corrosion.
China 420 stainless steel sheet executive standard:
GB/T 3280-2015 “Stainless Steel Cold Rolled Steel Sheet and Strip”
GB/T 4237-2015 “Stainless steel hot-rolled steel plate and strip”
GB/T 20878-2007 “Stainless steel and heat-resistant steel grades and chemical composition”
420 stainless steel plate in China:
New grades: 20Cr13, 30Cr13, 40Cr13.
Old grades: 2Cr13, 3Cr13, 4Cr13.
Characteristics and uses of China 420 stainless steel sheet:
20Cr13 stainless steel: high hardness in quenched state, good corrosion resistance. For steam turbine blades.
30Cr13 stainless steel: Harder than 20Cr13 after quenching, used as cutting tools, nozzles, valve seats, valves, etc.
40Cr13 stainless steel: Harder than 30Cr13 after quenching, used as cutting tools, nozzles, valve seats, valves, etc.
