Harsh Metalloys is a leading manufacturer and supplier of Stainless Steel 446 Pipes in Mumbai, India, providing high-quality solutions for high-temperature and oxidation-resistant applications. SS 446 is a ferritic stainless steel known for its excellent resistance to corrosion, scaling, and thermal fatigue, particularly in environments exceeding 1000°C. These pipes are ideal for industries requiring durable materials under extreme heat, such as furnaces, heat exchangers, and petrochemical processing. Harsh Metalloys offers Stainless Steel 446 pipes in various dimensions and specifications, ensuring outstanding performance, longevity, and cost-efficiency in demanding industrial applications where heat and corrosion resistance are critical.
Stainless Steel 446 Pipes primarily consist of chromium (23–27%), with low carbon content and minor additions of manganese, silicon, and molybdenum. This high chromium content offers excellent resistance to oxidation and sulfidation at elevated temperatures. The alloy has a tensile strength of approximately 485 MPa and yield strength around 275 MPa, with good creep and scaling resistance. Though not heat treatable, SS 446 pipes retain strength in high-heat environments. Harsh Metalloys ensures precision manufacturing, offering seamless and welded options with consistent wall thickness, surface finish, and mechanical integrity for high-temperature service.
