High Light	Corrosion Resistant Inconel 625 Plate ，High Strength Alloy 625 Sheet ，Hot Rolled Nickel-Chromium-Molybdenum-Niobium Strip

Inconel 625 Alloy 625 DIN2.4856 Plate Sheet

Manufactured in USA by SMC/ATI/HAYNES

General Properties

Alloy 625 is an austenitic nickel-chromium-molybdenum-niobium alloy offering exceptional corrosion resistance combined with high strength from cryogenic temperatures to 1800°F (982°C). The alloy's strength comes from solid-solution hardening by molybdenum and niobium, eliminating the need for precipitation-hardening treatments.

The chemical composition provides outstanding corrosion resistance in severe operating environments, with resistance to oxidation, carburization, pitting, crevice corrosion, impingement corrosion, intergranular attack, and virtual immunity to chloride stress corrosion cracking.

Alloy 625 is easily welded and processed using standard shop fabrication practices.

Applications

Aerospace Components - bellows and expansion joints, ducting systems, jet engine exhaust systems, engine thrust-reversers, turbine shroud rings
Air Pollution Control - chimney liners, dampers, flue gas desulfurization (FGD) components
Chemical Processing - equipment handling both oxidizing and reducing acids, super-phosphoric acid production
Marine Service - steam line bellows, Navy ship exhaust systems, submarine auxiliary propulsion systems
Nuclear Industry - reactor core and control rod components, waste reprocessing equipment

Corrosion Resistance

Alloy 625's highly alloyed composition provides exceptional corrosion resistance in severely corrosive environments. The alloy is virtually immune to attack in mild conditions including atmosphere, fresh and sea water, neutral salts, and alkaline solutions. Nickel and chromium provide resistance to oxidizing solutions, while nickel and molybdenum supply resistance in non-oxidizing environments.

Molybdenum provides resistance to pitting and crevice corrosion, and niobium acts as a stabilizer during welding to prevent intergranular cracking. The high nickel content makes Alloy 625 virtually immune to chloride stress corrosion cracking.

Fabrication Data

Hot Forming

The hot-working temperature range for Alloy 625 is 1650 - 2150°F (900 - 1177°C). Heavy working should occur near 2150°F (1177°C), while lighter working can take place down to 1700°F (927°C). Use uniform reductions to prevent duplex grain structure.

Cold Forming

Alloy 625 can be cold-formed using standard shop fabrication practices in the annealed condition. Work hardening rates are higher than austenitic stainless steels.

Welding

Alloy 625 can be readily welded by most standard processes including GTAW (TIG), PLASMA, GMAW (MIG/MAG), SAW and SMAW (MMA). No post weld heat treatment is necessary. Brushing with stainless steel wire brush after welding removes heat tint.

Machining

Machine Alloy 625 in the annealed condition. Due to work-hardening tendency, use low cutting speeds with continuous tool engagement and adequate cut depth to avoid work-hardened zones.
