ASTM B444 UNS N06625(INCONEL 625/DIN 2.4856) NICKEL ALLOY STEEL U-BEND TUBE

Inconel 625 is a nonmagnetic, corrosion and oxidation resistant, nickel-base alloy. It has high strength and toughness in the temperature range cryogenic to 2000°F (1093°C) which is derived largely from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix. Alloy 625 has excellent fatigue strength and stress - corrosion cracking resistance to chloride ions.
Typical applications for Alloy 625 have included heat shields, furnace hardware, gas turbine engine ducting, combustion liners, spray bars, chemical plant hardware and special seawater applications.Available forms are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges like inconel 625 plates, inconel 625 pipe, inconel 625 reducer, inconel 625 round bar, inconel 625 fittings, inconel 625 elbow, inconel 625 sheet, inconel 625 tube etc.
