High Carbon EN 1.4021 / DIN X20Cr13 / AISI 420 Stainless Steel Round Bar Hot Rolled Black Surface
1: AISI420 steel introduction
AISI 420 stainless steel (SS420) is a straight chromium martensitic stainless steel grade with certain wear resistance, corrosion resistance and high hardness.
It offers good ductility in its annealed state and excellent corrosion resistance properties when the metal is polished, surface grounded or hardened. This grade has the highest hardness - 50HRC - among all the stainless steel grades with 12% chromium.
Stainless steel grades that are similar to grade 420 stainless steels include martensitic steels such as the other versions of grade 420, having vanadium, sulphur and molybdenum in their composition, and the grade 440 series. Non-standard grade 420C has carbon content that is little higher than that of grade 420.
