1. What is UNS S31254?

UNS S31254(254 SMO) is a super-austenitic stainless steel with high molybdenum (6.0-6.5%), chromium (19.5-20.5%), and nitrogen (0.18-0.22%), designed for superior corrosion resistance in chloride-rich environments, including pitting, crevice corrosion, and stress-corrosion cracking (SCC). Its low carbon content ensures excellent weldability, making UNS S31254 material ideal for seawater systems, chemical reactors, and pulp/paper processing. Compared to UNS N08904, UNS S31254 offers higher pitting resistance (PREN ~43), making it better for severe chloride environments.

Gangsteel’s UNS S31254 alloy steel plate is crafted for demanding corrosive applications, offering a cost-effective alternative to nickel alloy steel grades like UNS N06625 or UNS N10276.
