NiCr22Mo9Nb corrosion-resistant alloy overview:
NiCr22Mo9Nb is a solid solution strengthened nickel-based deformed superalloy with molybdenum and niobium as the main strengthening elements. It has excellent corrosion resistance and oxidation performance. It has good tensile properties and fatigue properties from low temperature to 980 ℃, and is salt resistant Stress corrosion in a foggy atmosphere. Therefore, it can be widely used to manufacture aero engine parts, aerospace structural parts and chemical equipment. The alloy has good processing and welding performance, and can supply various plates, bars, pipes, wires, strips and forgings.
NiCr22Mo9Nb alloy is a corrosion-resistant, oxidation-resistant nickel-based alloy. The excellent strength and toughness exhibited by NiCr22Mo9Nb alloy in the low temperature-1093 ° C temperature range are derived from the solid solution effect of the refractory metal columbium and molybdenum in the nickel-chromium matrix. The excellent fatigue strength and resistance to stress corrosion cracking of NiCr22Mo9Nb alloy benefit from the chloride ion in the material.

NiCr22Mo9Nb corrosion-resistant alloy corrosion resistance:
NiCr22Mo9Nb alloy can withstand a variety of corrosive environments. In alkaline solutions, sea water, fresh water, neutral salts and air, the material has little corrosion. Nickel and chromium components provide antioxidant capacity. Nickel and molybdenum provide resistance to corrosion by non-oxidizing gases. Molybdenum can effectively prevent pitting and crevice corrosion. The resistance to chloride stress corrosion cracking is particularly prominent. At high temperatures, NiCr22Mo9Nb alloy is not prone to spalling or oxidation.
