254 SMO Steel Valves

254 SMO (CK3MCuN) is a high-alloy austenitic stainless steel developed for use in seawater and other chloride containing fluids. Falcon 254 SMO valves are designed with a combination of high impact toughness resistance to chloride stress corrosion (SCC), and pitting and crevice corrosion with strength that is twice that of SS316/SS304 stainless steel.
