Delivering high-quality stainless steel 309H tubing for corrosive and high-temperature industrial settings is the speciality of Harsh Metalloys, a prominent manufacturer and supplier in Mumbai, India. SS 309H Tubing, which is well-known for its strength and durability, is designed with premium materials and cutting-edge fabrication processes that satisfy global standards. These tubes are widely used in applications that call for exceptional heat and oxidation resistance. With an emphasis on timely delivery, quality control, and client satisfaction, Harsh Metalloys has established itself as a reliable partner for both domestic and international markets in sectors like thermal processing, petrochemicals, and power generation.
In order to increase its high-temperature strength, stainless steel 309H tubing has a higher carbon content (0.04–0.10%) than standard grades, along with 22–24% chromium and 12–15% nickel. At temperatures as high as 1100°C, these tubes provide outstanding resistance to oxidation and scaling. The material has an elongation of 40%, a yield strength of 205 MPa, and a tensile strength of roughly 550 MPa. Stability and mechanical performance are crucial in extreme thermal environments, and SS 309H Tubing is especially well-suited for extended service due to its increased carbon content, which enhances creep resistance.
