Inconel 625
Inconel 625 is a non-magnetic, corrosion- and oxidation-resistant nickel-base alloy. Its outstanding strength and toughness over the cryogenic to 2000°F (1093°C) temperature range is derived primarily from the solid solution effect of the refractory metals, columbium and molybdenum in a nickel-chromium matrix. The alloy has good fatigue strength and stress-corrosion cracking resistance to chloride ions. Some common applications for Alloy 625 include heat shields, furnace hardware, gas turbine engine ducts, combustion liners and spray bars, chemical plant hardware, and specialty seawater applications.

Corrosion Resistance
Inconel 625 has withstood many corrosive environments. Almost no attack occurs in alkaline, salty, freshwater, neutral salt or air. Nickel and chromium provide resistance to oxidizing environments. Nickel and molybdenum provide resistance to non-oxidizing atmospheres. Molybdenum prevents pitting and crack corrosion. Niobium stabilizes the alloy against sensitization during welding. Excellent resistance to chloride stress-corrosion cracking. This alloy is resistant to scaling and oxidation at high temperatures.
