Upgrade your industrial piping systems with Grade 625 nickel alloy buttweld fittings, meticulously crafted from a versatile nickel-based alloy known for exceptional corrosion resistance, high-temperature performance, and mechanical strength. These fittings conform to ASTM B366/B366M and ASME SB366 specifications, ensuring high-quality fabrication and dimensional accuracy. Available in a comprehensive range of types including elbows, tees, reducers, caps, and stub ends, Grade 625 fittings come in sizes ranging from 1/2″ to 12″ and larger, meeting diverse piping requirements. The buttweld design facilitates strong, leak-free connections, enhancing system integrity. Grade 625 nickel alloy fittings exhibit impressive mechanical properties, with a minimum tensile strength of 120 ksi (827 MPa) and a minimum yield strength of 60 ksi (414 MPa), suitable for high-pressure and high-stress applications. They offer exceptional corrosion resistance to seawater, acids, alkalis, and oxidizing chemicals, making them ideal for chemical processing, marine, offshore, and aerospace industries.
