Aditya Stainless is a reputable manufacturer and supplier of Stainless Steel 348H Pipe Fittings, located in Kolkata, India. We provide a top-notch selection of high-performance fittings that are built to endure high temperatures and harsh environments. Crafted from columbium-stabilized austenitic stainless steel, these fittings are perfect for pressure piping and high-temperature applications. Our SS 348H pipe fittings come in various forms, including elbows, tees, reducers, caps, and stub ends, all produced in line with international standards like ASME B16.9 and ASTM A403. At Aditya Stainless, we guarantee reliable and precisely dimensioned fittings for a wide range of industrial uses.
Stainless Steel 348H Pipe Fittings are made up of 17–19% chromium, 9–13% nickel, and are stabilized with columbium (niobium) and tantalum, featuring a higher carbon content for improved strength at elevated temperatures. These fittings boast a tensile strength of about 585 MPa, a yield strength of 240 MPa, and an elongation of around 35%. The alloy is known for its excellent creep strength, resistance to intergranular corrosion, and durability when exposed to prolonged heat. Its stabilized structure helps prevent carbide precipitation, making it a great choice for welded applications in challenging environments.
