Product Description
Inconel 625 Alloy 625 DIN2.4856 Plate & Sheet
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 Properties
- Outstanding corrosion resistance in severe operating environments
- Resistance to oxidation and carburization in high-temperature service
- Immune to chloride stress corrosion cracking
- Resistant to pitting, crevice corrosion, impingement corrosion, and intergranular attack
- Easily welded and processed using standard fabrication 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
Standards Compliance
- ASTM: B 443
- ASME: SB 443
- AMS: 5599
