Ed Stainless is a high-end supplier and producer of SMO 254 Channels in Houston, USA, providing corrosion-resistant structural parts for harsh environments. SMO 254 (UNS S31254) is a highly alloyed austenitic stainless steel with superior pitting, crevice corrosion, and chloride stress corrosion cracking resistance. SMO 254 channels are used for severe application in chemical, marine, and offshore environments and offer high mechanical strength and durability. Our SMO channels are made to ASTM specification and can be produced in different sizes and profiles, such as U and C channels. Ed Stainless provides competitive pricing, rapid delivery, and complete traceability for demanding structural applications.
SMO 254 has a composition of around 20% chromium, 18% nickel, 6% molybdenum, and nitrogen and copper additions. These components offer enhanced corrosion resistance, especially in seawater and hostile chemical environments. It possesses tensile strength of 94–109 ksi, yield strength ≥43 ksi, and elongation of about 35–50%. Its high PREN (Pitting Resistance Equivalent Number) >42 makes it a good fit for salt-environments. The alloy is very tough even at sub-zero temperatures and has good weldability and formability, and it is a secure option for highly corrosive and high-stress structural environments.
