Among their flagship offerings are the Stainless Steel 347 Round Bars and Rods, crafted specifically for tough applications that demand high-temperature strength and resistance to intergranular corrosion. SS 347 is a niobium-stabilized austenitic stainless steel, perfect for welded components and extended heat exposure. Aiman Metals ensures these round bars meet strict international standards, guaranteeing precision, durability, and consistency. Industries like aerospace, chemical processing, power generation, and oil & gas trust Aiman Metals for dependable stainless steel solutions.
Stainless Steel 347 Round Bars and Rods are made up of about 17–19% Chromium, 9–13% Nickel, and are stabilized with niobium (columbium) to avoid carbide precipitation. This alloy has a maximum carbon content of 0.08%, which enhances its weldability and performance at high temperatures. SS 347 boasts a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. It maintains excellent mechanical properties even after welding or prolonged heat exposure, making it perfect for applications that require strength, corrosion resistance, and thermal stability during continuous use.
