ASME SB163 Monel 400 UNS NO4400 Nickel Alloy SMLS Tube Evaporators Application
What is monel 400?
Monel400 alloy (UNS NO4400 or MCu-28-1.5-1.8 or Ni68Cu28Fe) is a
nickel-based alloy material with good corrosion resistance in
seawater, chemical solvents, ammonia, sulfur, chlorine, hydrogen
chloride, and a variety of acidic mediums, such as sulfuric acid,
hydrofluoric acid, hydrochloric acid, phosphoric acid, organic
acids, alkaline mediums, salts and molten salts. This alloy has a
strong, corrosion-resistant comprehensive performance, widely used
in chemical and other industries. For example, it is used in the
manufacture of heaters, heat exchangers, evaporators, distillation
kettles, distillation towers, condensers for fatty acid treatment,
equipment for the treatment of rosin-tinged acid, chemical pumps
and so on. As the alloy also has high strength and good oxidation
resistance at high temperatures, it can also be used in the heat
treatment industry, manufacturing a variety of structural
components. In the nuclear power industry, the alloy has good
corrosion resistance to high temperature and high pressure water.
Cold rolling is a plastic deformation process, which is
characterized by high dimensional accuracy, internal surface
finish, and has high mechanical properties.LG60 in the rolling of
Monel400, the surface of the pipe locally appeared spiral defects,
resulting in reduced productivity, yield reduction, to the latter
order of pipe rolling also brought about a negative impact.
Therefore, it is necessary to increase the grinding process to
eliminate the defect.
