Aiman Metals, located in Kuala Lumpur, Malaysia, stands out as a top manufacturer and supplier of high-performance stainless steel products. Among their wide range of offerings, the Stainless Steel 347 Square Bars and Rods are specially designed for high-temperature and corrosive settings. SS 347 is a niobium-stabilized austenitic stainless steel, celebrated for its resistance to intergranular corrosion and impressive mechanical properties even after welding and exposure to heat. Aiman Metals ensures these square bars meet international quality standards, catering to industries like petrochemical, aerospace, power generation, and chemical processing with precision-engineered, dependable stainless steel materials.
Stainless Steel 347 Square Bars and Rods are composed of 17–19% Chromium, 9–13% Nickel, and are niobium-stabilized to prevent carbide precipitation. The carbon content is capped at 0.08% max, which boosts weldability and high-temperature performance. SS 347 boasts a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%. It excels in resisting intergranular corrosion, even post-welding or after prolonged heat exposure, while maintaining mechanical stability at high temperatures. Its square shape adds dimensional strength, making it suitable for various structural and load-bearing applications.

Stainless Steel 347 Square Bars and Rods are perfect for high-temperature, high-stress situations where corrosion and oxidation resistance are essential. They find common use in heat exchangers, chemical processing equipment, furnace components, boiler tubes, and exhaust systems. Thanks to their niobium-stabilized structure, they are particularly well-suited for welded assemblies, effectively preventing intergranular corrosion after welding. Their square profile enhances strength and is frequently utilized in machinery frames, support structures, valve bodies, and fastening systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
