Inconel 625 Pipe elbows used widely in various industrial sectors in pipe fitting
This superalloy is composed mainly of nickel (58% min.) followed by chromium, and molybdenum, niobium, iron, tantalum, cobalt, and trace amounts of manganese, silicon, aluminium, and titanium.
The alloy 625 elbow has excellent fatigue strength and stress-corrosion cracking resistance to chloride ions. Some typical applications for alloy 625 have included heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware, and special seawater applications. Although the alloy was developed for high temperature strength, its highly alloyed composition also provides a significant level of general corrosion resistance. Alloy 625 elbow has withstood many corrosive environments. In alkaline, salt water, fresh water, neutral salts, and in the air, almost no attack occurs. The nickel and chromium provide resistance to oxidizing environments.
