Incoloy 840 Nickel Based Seamless Alloy Pipe UNS S33400 For Car Exhaust System

Incoloy 840 nickel based alloy seamless pipe UNS S33400 for Car exhaust system

Material designation: Incoloy 840 nickel based alloy
US grade: UNS S33400
Incoloy 840 Nickel Based Alloy Overview:
Incoloy 840 nickel based alloy alloys usually have a Cr content of 18-20% and a nickel content of 19-21%. Incoloy 840 alloy is an austenitic stainless steel containing titanium and aluminum. It contains enough chromium to form and maintain a sufficient amount of chromium oxide to protect it under high temperature conditions. It is more resistant to high temperature 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 the higher grade alloys used at temperatures up to 1900 degrees Fahrenheit (1038 ℃) . Therefore, Incoloy 840 alloy is an ideal material for manufacturing electric heating pipes, automotive emission control systems and other high temperature resistant products.
