Corrosion resistance
Generally, the corrosion resistance of solid solution Monel K500 is basically the same as that of Monel 400 alloy. Therefore, the corrosion resistance data of Monel 400 can be applied to Monel K500 alloy. Because of the low corrosion rate of the alloy in flowing seawater and the high strength of the alloy, the alloy is particularly suitable for making centrifugal pump shafts that are resistant to seawater corrosion.
The nuclear industry is used to manufacture equipment for uranium refining and isotope separation, seamless water pipes and steam pipes in power plants, seawater exchangers and evaporators, sulfuric acid and hydrochloric acid environments, crude oil distillation, pump shafts and propellers for equipment using seawater, The nuclear industry is used to manufacture equipment for uranium refining and isotope separation, and to manufacture pumps and valves used in hydrochloric acid production equipment.
Monel 400 alloy (UNS N04400 or MCu-28-1.5-1.8 or Ni68Cu28Fe) is a kind of alloy that can be used in seawater, chemical solvents, ammonia sulfur chloride, hydrogen chloride, various acidic media such as sulfuric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, organic acids , a nickel-based alloy material with excellent corrosion resistance in alkaline media, salts and molten salts.
Monel 400 is mainly used in chemical and petrochemical industries as well as marine development and other fields. It can be used to make various heat exchange equipment, boiler feed water heaters, petroleum and chemical pipelines, containers, towers, tanks, valves, pumps, reactors, shafts, etc.
Monel 400 processing
Monel 400 has excellent welding performance and can use TIG and MIG methods. It can use Monel body or EniCu-7 wire and electrode; or manual arc welding and submerged arc welding; it can be welded with carbon steel and low alloy steel.
This alloy has no plastic-brittle transition temperature, so it is very suitable for manufacturing various low-temperature equipment. Welding can increase the strength of the alloy, but reduces the plasticity of the alloy. Therefore, in order to maintain high plasticity, Monel K500 alloy needs to be heat treated after welding.
This alloy has comprehensive properties of strength, corrosion resistance, and is widely used in chemical and other industries. For example, it is used to make heaters, heat exchangers, evaporators, distillation kettles, distillation towers, condensers for fatty acid treatment, equipment for processing rosin acid, chemical pumps, etc. Because the alloy also has high strength and excellent oxidation resistance at high temperatures, it can also be used in the heat treatment industry to make various structural parts. In the nuclear power industry, this alloy has excellent resistance to corrosion by high-temperature and high-pressure water, so it is also an important structural material used in light water reactor nuclear power plants. The products include plates, rods, wires, strips, and pipes.
