Alloy K500 or Monel K-500 (UNS number N05500) is resistant to hydrogen sulphide, making the alloy highly suitable for sour gas applications. Low corrosion rates and toughness in seawater also make K500 (N05500) suitable for use in marine environments, including sub-sea and above-sea applications.
The high strength nature of the non magnetic alloy can be applied in a range of demanding environments. Kmonel, No5500 features low thermal expansion and long lasting corrosion resistance.
Nickel K500 is commonly supplied to specifications including QQ-N-286 Rev F/G, which defines the required chemical composition and mechanical properties for high-performance applications.
The alloy has been shown to be susceptible to pitting in stagnant water, and for long-term seawater applications, consider CNC-1® or T-1000.

Nickel k500 is a nickel-copper alloy with additions of iron, manganese, aluminium and titanium, which can be precipitation-hardened to produce a range of properties.
The alloy has excellent corrosion-resistance, very high strength and has good weldability. Nickel K500 has low corrosion rates in seawater and brackish flowing waters.
Nickel k500 is resistant to corrosion in hydrochloric and hydrofluoric acid in non-aerated conditions.
Chemical: The alloy is used in chemical, heat exchange and hydrocarbon processing equipment for pumps, valves, shafts, fittings and fasteners.
Marine: The corrosion resistant nature of Nickel K500 means that it is ideal for marine environments both subsea and above sea. Examples of use include splash zone sheathings in offshore structures, propeller and pump shafts.
