Incoloy 800

Incoloy 800 is Fe-Ni-Cr based solid solution strengthening deformation high temperature corrosion resistant alloy, used below 1000℃, Incoloy800 has excellent high temperature corrosion resistance and good process performance, good organizational stability, good processing and welding performance, the use of hot and cold processing are easy to form, It is suitable for making parts that require high temperature and long time working under harsh corrosive medium conditions, mainly including rod, plate, tube, belt, calcined parts and so on.
Incoloy800 has good stress corrosion crack resistance, stress corrosion crack resistance in water chloride, corrosion resistance of steam, air and carbon dioxide mixture, HNO3, HCOOH, CH3COOH, CH3CH2COOH and other organic acids corrosion resistance is good. it is commonly used in the production of petrochemical fields and various heat treatment furnace of various pipes, heat exchangers, liquid stills, etc.

Application field

Excellent stress corrosion resistance in water containing chloride and low concentration of NAOH, widely used in the manufacture of stress corrosion resistant equipment, instead of 18-8 austenitic steel, used in the power industry for pressurized water reactor evaporator, high temperature gas cooled reactor, sodium cooled fast reactor heat exchanger and superheated steam tube. In the chemical industry for HNO3 cooler, acetic anhydride cracking tube and various heat transfer equipment.
