AISI 420 3mm Thickness Stainless 420A 420C Hot Rolled Steel Sheet
AISI 420 Stainless 420A, 420B, 420C Hot Rolled Steel Strip, Coil, Sheet And Plate
420 stainless steel is a high-carbon steel with a minimum chromium content of 13%.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 - 55HRC - among all the stainless steel grades with 13% chromium.
| Grade | C | Si | Mn | Cr |
| 420A | 0.16~0.25 | 1.00 | 1.50 | 12.00~14.00 |
| 420B | 0.26~0.35 | 1.00 | 1.50 | 12.00~14.00 |
| 420C | 0.43~0.50 | 1.00 | 1.00 | 12.50~14.50 |
Martensitic Grades
Martensitic grades are magnetic and can be heat-treated by quenching or tempering.Martensitic steels are not as corrosive resistant as austenitic or ferritic grades,but their hardness levels are among the highest of the all the stainless steels.
Advantage of Hot rolled stainless steel sheet:
1. The strength of hot-rolled stainless steel plate is relatively low, and the surface quality is poor (oxidation/low finish), but good plasticity, generally medium-thickness plate, cold-rolled plate: high strength/high hardness, high surface finish, generally thin plate, can be used as Stamping board;
