Inconel 690 steel

Inconel 690 alloy is on the base is of Inconel 600 alloy, the chromium content increased to 30%, a new type of evaporator carbon content below 0.04% and the development of nickel base corrosion resistant alloy. It not only has excellent resistance to stress corrosion cracking ability, but also has high strength, good stability and excellent metallurgical processing capability. Characteristics, has been widely used in PWR nuclear power plant on the evaporator tube.
Inconel 690 alloy similar material are:UNS N06690
Inconel 690 alloy chief application:
Inconel 690 alloy is mainly used for the material of nuclear power plant steam generator tubes in pressurized water reactor.
