Alloy 625

Alloy 625 is a nickel-chromium alloy which has superior resistance to a wide range of corrosive environments as well as the high temperature effects of oxidation and carburisation.

Alloy 625 is excellent for sub-sea applications, having excellent pitting and corrosion properties, high corrosion fatigue strength and resistance to chloride-ion stress corrosion cracking. This alloy also demonstrates high strength properties, high tensile, creep and rupture strength, fatigue and thermal fatigue strength and oxidation resistance, making it suitable for many aerospace applications such as aircraft engine exhaust systems, housing engine controls and aircraft ducting systems. This alloy is also used in the nuclear field applications such as control rod components and heat exchanger tubing. Alloy 625 is also the alloy of choice for weld overlay applications in the oil and gas/petrochemical and refineries markets.
