Aditya Stainless is a reputed manufacturer and supplier based in Kolkata India, specializing in quality stainless steel. With years of experience in the industry, the company offers a wide range of stainless steel products, including stainless steel 309H pipe fittings, known for the exceptional strength and high heat resistance of we to ensure reliability and performance in every aspect is guaranteed excellence And the company’s reputation for customer satisfaction has made it a trusted name in the India and beyond.
Stainless Steel 309H Pipe Fittings are an alloy that contains 24-26% chromium and 19-22% nickel, which provide good oxidation resistance in high temperatures. The addition of carbon, with a range of 0.04-0.10%, enhances its strength and makes it suitable for elevated-temperature applications. These fittings provide high resistance to corrosion, especially in sulfur-containing environments. Mechanical properties include tensile strength of 515 MPa, yield strength of 205 MPa, and elongation of 40%. Stainless Steel 309H is weldable and formable. It is therefore used in high-temperature systems such as heat exchangers, furnace parts, etc.
