NS336、NS3306

Overview of NS336 (NS3306) corrosion-resistant alloy:

NS336 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.

NS336 alloy is a corrosion-resistant, oxidation-resistant nickel-based alloy. The excellent strength and toughness exhibited by the NS336 alloy in the low temperature-1093 ° C temperature range are derived from the solid solution effect of the refractory metals Co and Mo in the nickel-chromium matrix. The excellent fatigue strength and resistance to stress corrosion cracking of 625 alloy benefit from the chloride ion in the material.

NS336 (NS3306) corrosion resistance alloy corrosion resistance:

NS336 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, the NS336 alloy is not prone to flaking or oxidation.
