Starc Metals, based in Canberra, Australia, stands out as a top-notch manufacturer and supplier of high-quality SMO 254 Bars and Rods, specifically crafted for applications that demand extreme corrosion resistance. These bars and rods are renowned for their exceptional ability to resist pitting, crevice corrosion, and stress corrosion cracking, making them perfect for tough industrial settings. At Starc Metals, advanced production methods and rigorous quality control measures are employed to guarantee precision, durability, and consistent performance. Industries all over Australia trust these products for their remarkable strength, reliability, and longevity, especially in chemical processing, marine, desalination, and offshore applications where maximum corrosion resistance is a must.
SMO 254 Bars and Rods are made from a high-alloy austenitic stainless steel that contains about 20% chromium, 18% nickel, 6.1% molybdenum, 0.2% nitrogen, along with trace amounts of manganese and silicon. This unique blend gives them outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in environments rich in chlorides. On the mechanical side, SMO 254 Bars and Rods boast a tensile strength of 700 MPa, a yield strength of 320 MPa, and an elongation of 35%, all while maintaining excellent toughness and stability, even at higher temperatures. Their blend of mechanical strength and chemical resistance makes them perfect for handling highly aggressive conditions.

SMO 254 Bars and Rods are designed with a high content of chromium, nickel, and molybdenum, which provides excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. This composition makes them highly effective in aggressive environments, such as marine, chemical processing, and petrochemical industries, where high chloride concentrations are present.
Yes, SMO 254 Bars and Rods can be easily welded using standard welding techniques. However, it is important to follow proper procedures and use appropriate filler materials to maintain the material’s superior corrosion resistance and mechanical properties. This makes it suitable for critical applications where welded joints are required.
These bars and rods are widely utilized in industries that require top-tier corrosion resistance and long-lasting durability. You’ll often find them in chemical processing equipment, desalination plants, offshore structures, heat exchangers, and marine applications. They’re also well-suited for piping systems, valves, pumps, and storage tanks that come into contact with highly corrosive substances. Thanks to their excellent weldability, formability, and mechanical stability, they’re ideal for fabricating complex components in challenging environments. SMO 254 Bars and Rods guarantee reliable performance in industries where resistance to chloride-induced corrosion is critical.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
