420 Stainless Steel Coil
420 is a hardenable martensitic stainless steel that contains at least 12% chromium, just enough to provide corrosion resistance. It has good ductility in the annealed condition, but can be hardened to a minimum Rockwell hardness of 50 HRC, which is the highest hardness in the 12% chromium scale. Due to its hardening properties, 420 are not often welded, although this is possible. Martensitic stainless steel is designed for high hardness, and sometimes other properties will be affected to a certain extent. The corrosion resistance is lower than that of ordinary austenite grades, and its effective operating range is limited by its ductility loss at sub-zero temperatures and strength loss due to excessive tempering at high temperatures. The best corrosion resistance is obtained when the metal is hardened and subjected to surface grinding or polishing.
