420A is a martensitic stainless steel best used in the hardened, fine polished an passivated conditions in order to increase its toughness levels and make it ideal for generating a good cutting edge. It can be hardened by heat-treatment and also develops a good corrosion resistance to many chloride-free environments such as soaps, solvents and organic solutions.
