Monel K500 may be a precipitation-hardenable nickel-copper alloy that mixes the wonderful corrosion resistance characteristic of Monel four hundred with the more advantage of bigger strength and hardness. These amplified properties, strength and hardness, area unit obtained by adding atomic number 13 and Ti to the nickel-copper base and by a thermal process wont to impact precipitation, usually referred to as age hardening or aging. once within the age-hardened condition, Monel K-500 features a bigger tendency toward stress-corrosion cracking in some environments than Monel four hundred. Alloy K-500 has or so 3 times the yield strength and double the lastingness compared with alloy four hundred. Plus, it will be additional reinforced by cold operating before precipitation hardening. The strength of this alloy steel alloy is maintained to 1200° F however stays ductile and difficult right down to temperatures of 400° F. Its melting vary is 2400-2460° F.
This nickel-base alloy is spark resistant and non-magnetic to -200° F. However, it's potential to develop a magnetic layer on the surface of the fabric throughout process. atomic number 13 and copper could also be by selection modify throughout heating, going a magnetic nickel made film on the surface. Pickling or bright dipping in acid will take away this magnetic film and restore the non-magnetic properties.
