Description
SS 420 Round Bars (UNS S42000)
SS 420 Round Bars is a high-carbon steel with a minimum chromium content of 12%. Like any other stainless steel, grade 420 can also be hardened through heat treatment. 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.
Martensitic stainless steels are ones with high hardness and high carbon content. These steels are generally fabricated using methods that require hardening and tempering treatments. The operating conditions of martensitic steels are affected by loss of material’s strength at high temperatures, and decrease in ductility at negative temperatures.

Corrosion Resistance :
- • Under hardened conditions, grade 420 steels are resistant to fresh water, alkalis, air, foods and mild acids.
- • The steel grades with a smooth surface finish have excellent performance.
- • The corrosion resistance properties of grade 420 will tend to fall under annealed conditions.
- • The corrosion resistance of grade 420 is lower than that of the grade 430 Ferritic alloys with 17% chromium, grade 410 steels and other austenitic grades.
- • This steel grade finds application in cutlery such as carving knives, table knives and so on.
- • Grade 420 steels have good corrosion resistance against food, but continuous exposure of metals to unwashed food substances can lead to pitting corrosion.
