Home > Stainless Steel > SMO 254 Nuts
SMO 254 Nuts are available in SMO 254, a high-alloy austenitic stainless steel with superior corrosion properties. These nuts are suitable for use in hostile environments such as chemical processing, seawater, and desalination, where high resistance to pitting, crevice corrosion, and stress corrosion cracking is desirable. They provide high strength and durability and can be used in industries where high performance is expected under tough conditions.
