Alloy 625
Alloy 625, also known as Inconel® 625 is a nickel-chromium-molybdenum-columbium (niobium) alloy with excellent oxidation resistance, corrosion resistance and strength at high temperatures.
Age hardening treatments are not required to maintain the high strength properties of Alloy 625 due to the solid solution effects of molybdenum and columbium on the nickel-chromium matrix.
Alloy 625 is resistant to chloride ion stress corrosion cracking, pitting, and stress corrosion cracking, making it suitable for seawater applications.
Alloy 625 can be used at cryogenic temperatures up to 700°F (370°C).
Alloy 625 is used in markets applications such as automotive, marine, chemical processing, power generation, nuclear power, and aerospace....
Applications include honeycombs, springs, seals, bellows, diaphragms, land-based turbine components, aircraft exhaust ducts and heat exchangers.
