Incoloy 840 Description
Nickel-based super alloy Incoloy 840 (Alloy 840/UNS S33400): Incoloy 840 nickel-based alloy: The Cr content in Incoloy 840 nickel-based alloy alloy is usually 18-20%, and the nickel content is 19-21%. Incoloy 840 alloy is a kind of austenitic stainless steel containing titanium and aluminum. It contains enough chromium to form and maintain a sufficient scale of chromium oxide to protect it under high temperature conditions and is more resistant to high temperatures than traditional chromium-nickel stainless steels such as 304; The higher nickel content makes it have better oxidation resistance than the standard 18-8 stainless steel, and its oxidation resistance is not inferior to higher-grade alloys whose service temperature is as high as 1900°F (1038°C) . Therefore, Incoloy 840 alloy is an ideal material for manufacturing electric heating pipes, automobile emission control systems and other high temperature resistant products.
