Inconel 718 Pipe Fittings are primarily composed of nickel (50-55%) and chromium (17-21%), with additional elements like molybdenum (2.8-3.3%), niobium (4.75-5.5%), iron, and trace amounts of titanium and aluminum. This composition provides excellent resistance to oxidation and corrosion. Inconel 718 offers high tensile strength (965 MPa), yield strength (550 MPa), and exceptional creep resistance at temperatures up to 700°C. It boasts a hardness of 250 HB and impressive fatigue and rupture strength, making it ideal for high-stress, high-temperature applications.

The Stainless Steel 304L Buttweld Fittings we provide in Wellington are made from low-carbon 304L stainless steel, which enhances their weldability while reducing the risk of carbide precipitation. These fittings contain about 18–20% chromium and 8–12% nickel, with a low carbon content (≤0.03%) that boosts their corrosion resistance. They boast impressive mechanical properties, featuring a tensile strength of around 485 MPa and a yield strength of 170 MPa. Even at low temperatures, they maintain good ductility and toughness, making them perfect for structural and pressure applications where long-term performance is essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
