Inconel800 Material introduction
Inconel800((UNS N08800)) is Fe-Ni-Cr Base solid solution strengthened deformed superalloy, used below 1000 ℃. The alloy has excellent high temperature corrosion resistance, good processing properties and good structural stability. The alloy has good processing and welding properties, and it is easy to form by cold and hot processing. The alloy is suitable for making parts that require high temperature and long time operation under harsh corrosive medium conditions. The main products are hot rolled and forged bars, hot rolled plates, cold rolled sheets, cold rolled (drawn) seamless tubes, cold rolled strips and forgings。
