Product Description
Inconel 625 Alloy Plate & Sheet
Premium corrosion-resistant nickel-chromium-molybdenum-niobium alloy plates and sheets manufactured in the USA by SMC/ATI/HAYNES. Available in thicknesses from 0.5mm to 16mm.
Material 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
- Excellent weldability and fabrication properties
Industry 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 for oxidizing and reducing acids
- Marine Service: steam line bellows, ship exhaust systems
- Nuclear Industry: reactor core components, waste reprocessing equipment
- Offshore Oil & Gas: flare gas stacks, piping systems, riser sheathing
