Monel 500 bar
Descripition:
Monel K-500 is a nickel-copper alloy which combines the excellent corrosion resistance of Monel 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening or aging.
*Feature
Corrosion resistance in an extensive range of marine and chemical environments. From pure water to non-oxidizing mineral acids, salts and alkalis.
Excellent resistance to high velocity sea water
Resistant to a sour-gas environment
Excellent mechanical properties from sub-zero temperatures up to about 480C
Non-magnetic alloy
Monel K-500 Chemical composition:
| Alloy | % | Ni | Cu | Al | Ti | Fe | Mn | S | C | Si |

Monel K-500 Physical properties:
| Density | 8.44 g/cm3 |
| Melting point | 1315-1350°C |
Monel K-500 minimum mechanical properties in the room temperature:
| Status | Tensile strength Rm N/mm2 | Yield strength RP0.2N/mm2 | Elongation A5 % |
| Monel K500 | 1100 | 790 | 20 |
Alloy K-500 has approximately twice the tensile strength and triple the yield strength of Alloy 400. The strength of Alloy K-500 is maintained to 1200 degrees Fahrenheit, but stays ductile and tough down to temperatures of -400 degrees Fahrenheit. Alloy K-500 also stays non-magnetic to -200 degrees Fahrenheit.
Additional characteristics of Alloy K-500 include outstanding corrosion resistance in a wide range of chemical and marine surroundings, from salts and alkalis, non-oxidizing acids to pure water. Alloy K-500 is non-magnetic and spark resistant. It is also recommended that Alloy K-500 be annealed when it is welded and that any weldments be stress relieved prior to aging.
