Product Description

ASTM A312 S31254 SMO 254 Seamless Pipe High Temperature Seawater

What is S31254 material?

NAS 185N (SUS 312L, UNS S31254,SMO 254) is a high corrosion resistant austenitic stainless steel with a high nickel, high chromium, high molybdenum alloy design, and provides excellent corrosion resistance in severe corrosion environments such as high temperature seawater.


SMO 254(UNS S31254) is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties:

-Excellent resistance to pitting and crevice corrosion, PRE = ≥42.5*
-High resistance to general corrosion
-High resistance to stress corrosion cracking
-Higher strength than conventional austenitic stainless steels
-Good weldability
