About
A312 UNS S31254 is a specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes. It is commonly known as 6% Moly or 254 SMO (Super Austenitic Stainless Steel). This alloy offers excellent resistance to pitting, crevice corrosion, and general corrosion in various aggressive environments, including chloride-containing media. A312 UNS S31254 pipes are widely used in industries such as chemical processing, oil and gas, pulp and paper, and desalination plants, where corrosion resistance is of utmost importance. These pipes are available in different sizes and schedules to meet specific project requirements.
