Largest Stainless Steel 316 / 316L Buttweld Fittings Supplier in Chennai, India
Stainless Steel 316 / 316L Buttweld Fittings are mainly made up of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%) content, which increases corrosion resistance especially against chlorides and acidic media. 316L has a lower carbon content (max 0.03%) than 316 (max 0.08%), lowering the possibility of carbide precipitation upon welding and enhancing weldability. These fittings offer superior mechanical strength with a tensile strength of around 515 MPa and yield strength of 205 MPa, as well as superior ductility and toughness in cryogenic and high-temperature conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
