Monel 500 strip
Monel K500 material is a 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 aging. 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.

Monel K500 (UNS0500/ DIN W.Nr 2.1375)
Monel K-500 combines Monel 400’s excellent corrosion resistance with greater strength and hardness as a result of adding aluminum and titanium and proper heat treatment to cause precipitation hardening. It is nonmagnetic at temperatures as low as -101℃. Monel K-500 has excellent dimensional stability which is very useful in high precision devices. Like Monel 400, it does not undergo ductile-to-brittle transition at cryogenic temperatures as low as that of liquid hydrogen. Its tensile and yield strengths increase while ductility and toughness are only slightly impaired.
