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.

Casting Grade : A351 CK3MCuN

Forging Grade : A182 F44

Wrought UNS : S31254

Cast UNS : J93254

Specifications

• Size: ½” to 24” 
• Class: 150# to 2500#

Following type of Valves are manufactured by Falcon 

• 254 SMO Gate valves
• 254 SMO Globe valves
• 254 SMO check valves
• 254 SMO Ball valves
• 254 SMO butterfly valves
• 254 SMO Strainers
• 254 SMO Plug valves

Characteristics of 254 SMO valves

254 SMO has a very low carbon content. Pitting resistance equivalent number (PREN) is above 42.5 hence it provides good corrosion resistance in water containing chlorides.

Application of 254 SMO valves

• Seawater lines
• Desalination plants
• Oil refineries distillation columns 
• Food industries
• Chemical plants
• Paper and Pulp industries
