Inconel 690 (UNS N06690)
Inconel 690 is a high-chromium nickel alloy with 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.

* Feature
鈼?Excellent inoxidability in the high temperature.
鈼?Good resistance to carbonizing.
鈼?Good inoxidabilitiy in sulfur atmosphere
鈼?Good mechanical property in both room temperature and high temperature.
鈼?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鈩?environment.
* Application
鈼?The tray,basket and tool clamp in the heat treatment factory.
鈼?Steel shares at annealing and radiation control, high-speed gas burners, Industrial furnace silk screen.
鈼?Separate tank of ammonia reforming and catalytic support grid of nitric acid producing.
鈼?Exhaust system parts
鈼?Solid waste incinerator's combustion chamber
鈼?Channel support and soot dealing parts.Wholesale Inconel Alloys
