The Stainless Steel 316/316L Forged Fittings from Khuliso Fittings are crafted from a blend of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum. This molybdenum content significantly boosts resistance to pitting and crevice corrosion, making these fittings ideal for marine and chemical applications. The 316L variant, with its lower carbon content, enhances weldability and minimizes the risk of carbide precipitation. These fittings boast a tensile strength of around 515 MPa and a yield strength of approximately 205 MPa, ensuring excellent ductility and toughness, even in freezing temperatures.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
