420 Stainless Steel Plates & Sheets

Alloy 420 is a hardenable, martensitic stainless steel that is an alteration of Alloy 410. Alloy 420 has higher carbon content than Alloy 410 which is intended to advance quality and hardness attributes. It has great malleability it the strengthened condition yet is equipped for being solidified up to Rockwell hardness 50 HRC, the most elevated hardness of the 12% chromium grades. Because of its solidifying properties, Alloy 420 is not regularly welded, in spite of the fact that it is conceivable. Martensitic stainless steels are intended for high hardness and here and there different properties are to some degree bargained. Erosion resistance is lower than the basic austenitic evaluations and their valuable working reach is restricted by their loss of malleability at below zero temperatures and loss of quality by over-treating at hoisted temperatures. Its best erosion resistance is accomplished when the metal is solidified.
