Product Description
High Strength Hot/Cold Rolled Inconel 625 Plate
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
