4.Characteristics
Ni-Cr-Iron alloy,solid solution strengthening.
Good resistance to high temperature corrosion and oxidation resistance.
Excellent hot and cold processing and welding performance.
A satisfactory heat intensity and high plasticity until 700℃.
Can be strengthened through the cold work,also can use resistance welding,welding or soldering connection.
Good corrosion resistance：
Corrosion resistance to all kinds of corrosive media.
Chromium compounds make the alloy have better corrosion resistance than nickel 99.2 (200) alloy and nickel (alloy 201,low carbon) under the condition of oxidation.
At the same time,the high content of nickel alloy shows good corrosion resistance in alkaline solution and in reduction conditions,and can effectively prevent the chloride-iron stress corrosion cracking.
Very good corrosion resistance in acetic acid,acetic acid, formic acid,stearic acid and other organic acids,and corrosion resistance in inorganic acid media.
Excellent corrosion resistance in a nuclear reactor in primary and secondary circulation use of high purity water.
Particular prominent performance is the ability to resist dry chlorine and hydrogen chloride corrosion, application temperature can be up to 650℃.At high temperature,the alloy of annealing and solid solution treatment states in air has the very good antioxidant performance and high peeling strength.
The alloy also shows resistance to ammonia and nitriding and carburizing atmosphere, but in the REDOX conditions changed alternately alloy will be influenced by partial oxidation corrosion media.
5.Applications
Application field is very broad: aircraft engine parts,erosion thermowells in atmosphere,the production and use of caustic alkali metal field,especially the use of sulfur in the environment,the heat treatmen furnace retort and components,especially in the carbide and nitride atmosphere,petrochemical industry in the production of catalytic regenerator and reactor,etc.
