Reputable Mumbai, India-based manufacturer and supplier Harsh Metalloys provides premium stainless steel 309H pipes made to withstand high temperatures and corrosive conditions. International standards for strength, durability, and corrosion resistance are met by these pipes, which are precisely fabricated from premium materials. Applications needing prolonged exposure to high temperatures and demanding industrial conditions are best suited for SS 309H pipes. Serving the power generation, petrochemical, refinery, and heat treatment industries in India and abroad, Harsh Metalloys is renowned for its dedication to quality, prompt delivery, and customer satisfaction.
Stainless steel 309H pipes have a higher carbon content (0.04–0.10%) than 309S, which improves their high-temperature strength. They are mainly made of 22–24% chromium and 12–15% nickel. At temperatures as high as 1100°C, these pipes provide exceptional resistance to oxidation and corrosion. Their mechanical characteristics include an approximate elongation of 40%, a yield strength of 205 MPa, and a tensile strength of 550 MPa. Because of their improved creep resistance due to their higher carbon content, SS 309H pipes can withstand extended use in hot conditions without compromising their structural soundness or functionality.
