Grade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. It can be hardened through heat treatment, offering good ductility in annealed state and excellent corrosion resistance when polished, surface grounded or hardened. With a hardness up to 50HRC, it has the highest hardness among all stainless steel grades containing 12% chromium.

Under hardened conditions, grade 420 steels resist fresh water, alkalis, air, foods and mild acids. Surface finish significantly affects performance, with smoother finishes offering better corrosion resistance. Common applications include cutlery such as carving knives and table knives.
Annealing: 840 to 900°C, slow furnace cooling to 600°C then air-cooling
Hardening: 980 to 1035°C followed by air or oil quenching
Tempering: 150 to 370°C (avoid 425-600°C range)
Grade 420 stainless steels require pre-heating at 150 to 320°C and post-heating to 610 to 760°C. Recommended welding rods include grade 420 metals for high-strength joints or grade 309 for ductile joints.
