Alloy59 is a nickel-based high-temperature alloy with excellent high-temperature and corrosion resistance, suitable for aerospace, petrochemical and other fields. It contains chromium, nickel, molybdenum and other elements, and has the characteristics of low magnetism, oxidation resistance, high-temperature stability, and good processing and welding performance.
- Excellent resistance to pitting corrosion, crevice corrosion and chloride-induced stress corrosion cracking.
- Excellent corrosion resistance to inorganic acids, such as nitric acid, phosphoric acid, sulfuric acid and hydrochloric acid, especially to the mixture of sulfuric acid and hydrochloric acid.
- Excellent resistance to corrosion by various inorganic acid mixed solutions.
- Good corrosion resistance in hydrochloric acid solutions of various concentrations up to 40°C (104°F).
- Good machinability and weldability, no post-weld cracking sensitivity.
- Certified for the manufacture of pressure vessels with wall temperatures between -196 and 450°C.
- Certified by the American Association of Corrosion Engineers NACE standard (MR-01-75) to meet the highest standard level VII for use in sour gas environments.
Application fields
- Aerospace: used to manufacture aircraft parts and rocket parts due to its light weight, high strength, high temperature resistance and wear resistance.
- Petrochemical field: used to manufacture reactors, towers, heat exchangers and other equipment in high temperature, high pressure and corrosive environments.
Corrosion resistance
Alloy59 can maintain stable performance in strong corrosive media such as acids, alkalis, chlorides, etc., and has the advantage of long service life. At the same time, it also shows good resistance to pitting and boiling corrosion, and can be used for a long time in high temperature and high relative humidity environments.
