1. What is 254 SMO Stainless Steel?

254 SMO stainless steel(UNS S31254, EN 1.4547) is a super austenitic stainless steel designed for superior resistance to pitting, crevice corrosion, and stress corrosion cracking. With high chromium (19.5-20.5%), nickel (17.5-18.5%), molybdenum (6.0-6.5%), and nitrogen (0.18-0.22%), 254 SMO material delivers outstanding performance in chloride-heavy environments, surpassing standard grades like 904L. Its low carbon content (≤0.02%) ensures excellent weldability, making 254 SMO stainless steel plate ideal for marine, chemical processing, and pulp and paper industries.

Gangsteel’s 254 SMO stainless steel is crafted for demanding conditions, offering a cost-effective alternative to nickel alloy steel grades such as Alloy C-276 for applications requiring robust corrosion resistance.
