Alloy Steel Sheets UNS N04400/N05500 Monel Nickel Plate for Structure Application
Monel 400:
Monel 400 alloy is high-intensity single-phase solid solution,Monel 400 (Ni 67%) is made of a Nickel-Copper alloy that offers outstanding corrosion resistance in seawater. Monel 400 better withstands oxidation attack as compare to other copper based alloys and significantly prevents attack by sulfuric acid, hydrofluoric acid, hydrochloric acid, nitric acid, hydrofluoric acid and alkalis. It offers outstanding resistance to steam and has good toughness that makes it an ideal material for use in the oil refining industries.
Monel alloy 400 can retain its hardness at the various temperature limits. In annealed condition, monel alloy can be used up to 1000oF or 480oC. It has medium to high strength, fine weldability and exceptional mechanical characteristics at subzero temperatures. Alloy 400 is more economical and superior than Nickel.
Monel K-500:
Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of greater strength and hardness. These amplified properties, strength and hardness, are obtained by adding aluminum and titanium to the nickel-copper base and by a thermal processing used to effect precipitation, typically called age hardening or agin.When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400. Plus, it can be further strengthened by cold working prior to precipitation hardening. The strength of this nickel steel alloy is maintained to 1200° F but stays ductile and tough down to temperatures of 400° F. Its melting range is 2400-2460° F.This nickel alloy is spark resistant and non-magnetic to -200° F. However, it is possible to develop a magnetic layer on the surface of the material during processing. Aluminum and copper may be selectively oxidized during heating, leaving a magnetic nickel rich film on the outside. Pickling or bright dipping in acid can remove this magnetic film and restore the non-magnetic properties.
