What is 254 SMO?
254 SMO is a 6-Moly grade designed specifically for warm seawater and halide service where 316L and even 904L pit. The nitrogen addition contributes strongly to pitting resistance and raises strength above conventional austenitics. It remains fully austenitic, so unlike duplex it keeps its toughness and non-magnetic behaviour.
Designations
254 SMO Super Austenitic Stainless Steel is also designated UNS S31254, EN 1.4547, AISI 254 SMO, GB S31254 and Werkstoff X1CrNiMoCuN20-18-7. Quote the designation your specification uses and we will supply to it.
Why choose 254 SMO seamless Pipes
Resists pitting and crevice attack in warm seawater, Higher strength than 316L while remaining fully austenitic, Excellent resistance to chloride stress corrosion cracking and Non-magnetic and tough at cryogenic temperature. It is non-magnetic, with requires-procedure weldability and difficult machinability, and is used in continuous service in air up to about 400 °C.
Limitations to specify around
Among the most expensive stainless options per tonne, Requires over-alloyed filler metal when welded, Difficult to machine and Availability is limited to held stock and mill order. We state these plainly so the grade is chosen for the right service.
