Chemical Process Industry Anti-Corrosion Wear Resistance Nickel-Based Alloy Inconel 625 Sheet
General Description
Inconel 625, a nickel-chromium-molybdenum alloy contains 9% Moly, serves effectively as both a corrosion resistant and heat resistant material. The combination of high-temperature strength and resistance to halogen attack, oxidation, and carburization has made alloy 625 a popular choice for chemical and petrochemical process equipment exposed to hostile, hightemperature environments.
The high alloy content of Inconel 625 enables it to withstand a wide variety of corrosive environments. The alloy is almost completely resistant to mild environments such as the atmosphere, fresh water and seawater, neutral salts, and alkaline media. In more severe environments, the combination of nickel and chromium provides resistance to oxidizing chemicals, and the combination of nickel and molybdenum provides resistance to reducing conditions. The molybdenum content also makes Inconel 625 highly resistant to pitting and crevice corrosion. The columbium stabilizes the alloy against sensitization and prevents intergranular corrosion. The high nickel content provides freedom from chloride stress-corrosion cracking.
Inconel 625 made by NiWire is made into chemical processing equipment, aircraft engine and airframe components, ship and submarine parts

Welding of Inconel 625
Any traditional welding procedures can be used to weld Inconel 625 to similar alloys or other metals, such as gas tungsten arc welding(GTAW), plasma arc welding (PAW), metal inertia gas welding (MIG) and so on. Before welding, remove scale, grease, mark and imprint. And no heat treatment needed before and after welding. Recommend filler wire regarding welding Inconel 625: ERNiCrMo-3
Size Range
Inconel 625 wire, bar, rod, forging, plate, sheet, tube, fastener, pipe fittings and other standard forms are available.
