Isis Metals stands out as a reliable manufacturer and supplier of SMO 254 Hex Bars and Rods right in Manila, Philippines. They specialize in high-performance stainless steel products that are built to thrive in extreme corrosion environments. Known as UNS S31254, SMO 254 is a super austenitic stainless steel that offers remarkable resistance to pitting, crevice corrosion, and stress cracking. At Isis Metals, you can expect precision-engineered hex bars and rods that boast superior mechanical properties and excellent weldability. These products find their place in various industries, including marine, chemical processing, pulp and paper, and desalination, where durability and reliability are crucial in tough conditions.
SMO 254 Hex Bars and Rods are made up of 20% Chromium, 18% Nickel, 6% Molybdenum, along with added Nitrogen and Copper to boost corrosion resistance. This alloy showcases a tensile strength of around 650 MPa, a yield strength of 300 MPa, and an elongation of 35–45%, ensuring outstanding toughness even in cryogenic temperatures. With a Brinell hardness of 210 HB, it offers excellent formability and weldability. Thanks to its high molybdenum and nitrogen content, it stands out for its resistance to chloride-induced corrosion, making it a better choice than standard stainless steels like 316L in aggressive environments.
