Product Description

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 Features:

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 standard shop fabrication compatibility

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
