Uses: Molds, accessories, plastic molds, corrosion resistance and mirror rust prevention mold, etc. 1Cr17Ni2 series is a kind of steel with good strength and toughness in martensitic stainless steel. It has good corrosion resistance to aqueous solutions of oxidizing acids, most organic acids and organic salts. Generally suitable for the manufacture of nitric acid, acetic acid production and light industry, textile and other industries require both strong toughness and corrosion resistance of the shaft, piston rod, pump and other parts.
