Harsh Metalloys is a reputed manufacturer and supplier of Stainless Steel 439 Pipes based in Mumbai, India, delivering high-quality piping solutions for automotive, industrial, and architectural applications. Stainless Steel 439 is a ferritic stainless steel grade stabilized with titanium, offering excellent resistance to corrosion, oxidation, and high-temperature scaling. Known for its superior formability and weldability compared to other 400-series grades, SS 439 pipes are widely used in exhaust systems, heat exchangers, and structural components. At Harsh Metalloys, we supply SS 439 pipes in various diameters and wall thicknesses, available in seamless and welded forms to meet diverse industry standards.
Stainless Steel 439 Pipes are composed primarily of chromium (17–19%), with added titanium to improve weldability and corrosion resistance. The low carbon content enhances resistance to intergranular corrosion and makes the material suitable for welding without the need for post-weld annealing. SS 439 offers a tensile strength of approximately 380–450 MPa and good ductility. The alloy maintains excellent oxidation resistance at elevated temperatures and exhibits good thermal conductivity. Harsh Metalloys ensures that every SS 439 pipe meets stringent quality benchmarks with precision tolerance, clean internal surfaces, and consistent mechanical properties.
