SS43 1 system is a martensitic stainless steel with good strength and toughness. It has good corrosion resistance to oxidizing acids, most organic acids and organic salt solutions. It is generally suitable for manufacturing shafts, piston rods, pumps and other parts that require both toughness and corrosion resistance in nitric acid and acetic acid production, light industry, textile and other industries.
The chemical composition of SS43 1 is as follows:
