INCONEL alloy 690 is a high-chromium nickel alloy having excellent resistance to many corrosive aqueous media and high-temperature atmospheres. The alloy’s high chromium content gives it excellent resistance to aqueous corrosion by oxidizing acids (especially nitric acid) and salts, and to sulfidation at high-temperatures. In addition to its corrosion resistance, alloy 690 has high strength, good metallurgical stability, and favorable fabrication characteristics.

Seamless pipe and tube
B 619, B 775
B 626, B 751
Forged or rolled pipe flange and forged fitting
Billet and bar for reforging
Characteristic as below：
1.Excellent inoxidability in the high temperature.
2.Good resistance to carbonizing.
3.Good inoxidabilitiy in sulfur atmosphere
4.Good mechanical property in both room temperature and high temperature.
5.Good resistance to stress corrosion cracking, 690 have high creep rupture strength since it limits the carbon content and grain size, so recommend to use for above 500℃ environment.
Inconel 690 Application field：
1.The tray,basket and tool clamp in the heat treatment factory.
2.Steel shares at annealing and radiation control, high-speed gas burners, Industrial furnace silk screen.
3.Separate tank of ammonia reforming and catalytic support grid of nitric acid producing.
4.Exhaust system parts
5.Solid waste incinerator's combustion chamber
6.Channel support and soot dealing parts.
