Inconel 625

Inconel 625 is a nickel-chromium-molybdenum alloy. Its outstanding strength and toughness in the temperature range cryogenic to 2000°F (1093°C), which are derived primarily from the solid solution effects of niobium and molybdenum in its nickel-chromium matrix. The alloy has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. 

Typical applications for Inconel 625 are heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware, and special seawater applications.
