Product Description
High Strength Hot/Cold Rolled Inconel 625 Plate
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.
Key Characteristics:
- Outstanding corrosion resistance in severe operating environments
- Resistance to oxidation and carburization in high temperature service
- Immunity to chloride stress corrosion cracking
- Resistance to pitting, crevice corrosion, and intergranular attack
- Easy welding and fabrication using standard shop practices
Applications
- Aerospace Components: Bellows, expansion joints, ducting systems, jet engine exhaust systems
- Air Pollution Control: Chimney liners, dampers, flue gas desulfurization components
- Chemical Processing: Equipment handling oxidizing and reducing acids
- Marine Service: Steam line bellows, Navy ship exhaust systems
- Nuclear Industry: Reactor core components, waste reprocessing equipment
- Offshore Oil & Gas: Waste flare gas stacks, piping systems, riser sheathing
- Petroleum Refining: Waste flare gas stacks
- Waste Treatment: Waste incineration components

Corrosion Resistance
Alloy 625 demonstrates outstanding corrosion resistance in severely corrosive environments, with virtual immunity to attack in mild conditions including atmosphere, fresh and sea water, neutral salts, and alkaline solutions. The combination of nickel, chromium, and molybdenum provides comprehensive protection against both oxidizing and non-oxidizing environments.
Fabrication Data
Hot Forming
Working temperature range: 1650-2150°F (900-1177°C). Heavy working should occur near 2150°F (1177°C) with uniform reductions to prevent duplex grain structure.
Cold Forming
Can be cold-formed using standard practices in annealed condition. Work hardening rates are higher than austenitic stainless steels.
Welding
Readily welded by GTAW (TIG), PLASMA, GMAW (MIG/MAG), SAW and SMAW (MMA) processes. No post weld heat treatment required.
Machining
Should be machined in annealed condition using low cutting speeds and adequate cut depth to avoid work-hardened zones.
