Mirza Pipe and Tubes supplies Stainless Steel 439 pipes from Riyadh, Saudi Arabia, offering affordable and corrosion-resistant solutions for automotive, heat exchanger, and exhaust system applications. SS 439 is a titanium-stabilized ferritic stainless steel, providing good resistance to oxidation, corrosion, and high-temperature scaling. It is commonly used in environments needing an aesthetic finish and moderate corrosion resistance. Our 439 pipes come in various dimensions and wall thicknesses, manufactured to meet international specifications and customized for industrial clients across Saudi Arabia and the Gulf region.
SS 439 contains 17–19% chromium, low carbon (<0.03%), and titanium for stabilization. It has a tensile strength of 380–540 MPa and good oxidation resistance at elevated temperatures. Benefits include high thermal conductivity, good formability, weldability, and superior resistance to intergranular corrosion after welding. It performs well in mildly corrosive environments and is more economical than austenitic grades. SS 439 is suitable for replacing 304/409 where cost efficiency and durability are needed.
