stainless-steel-coil-431s29 is a kind of martensitic stainless steel with good strength and toughness, which can get higher strength and hardness through heat treatment. It has good corrosion resistance to oxidizing acids (certain temperature, concentration of nitric acid, most organic acids) and organic acid aqueous solution.
