What is A312 S31254?

254 SMO pipe to A312/SA312 for general corrosive service. Strength guide: high PREN superaustenitic — confirm SA-312 / PO.

Typical applications

  • Seawater and brine systems
  • Flue-gas desulphurisation and scrubbers
  • Aggressive chloride chemical process

Selection guidance

Select 254 SMO when 904L/317L PREN is insufficient. Cross-check vs super duplex 2507 for strength + chloride duty.
