Monel K500 Pipe Fittings are high-performance nickel-copper alloy components designed for demanding industrial applications. Combining the corrosion resistance of Monel 400 with added strength through age-hardening, Monel K500 fittings deliver exceptional durability and reliability. They are widely used in marine, chemical processing, and power generation industries where resistance to seawater, acids, and alkalis is critical.
Monel K500 is primarily composed of nickel and copper, with small additions of aluminum and titanium to enhance strength. This unique composition allows the fittings to withstand high-stress environments while maintaining excellent corrosion resistance. The alloy’s properties make it ideal for piping systems that handle harsh chemicals, high-pressure fluids, and extreme temperature variations.
Monel K500 pipe fittings are nickel-copper-based alloys engineered for high strength, corrosion resistance, and durability in extreme environments. With superior mechanical properties compared to Monel 400, these fittings are widely used in chemical processing, marine, offshore oil and gas, and aerospace industries. They are ideal for systems that require both corrosion resistance and high structural integrity.
Monel K500 contains approximately 63% nickel and 28–34% copper, similar to Monel 400, but with additional elements like aluminum and titanium. These additions allow the alloy to be age-hardened, providing significantly higher mechanical strength while retaining excellent corrosion resistance in seawater, acids, and alkalis.

Our Monel K500 Pipe Fittings come in a wide range of types and sizes, including elbows, tees, reducers, caps, and flanges. Each fitting is manufactured to meet stringent industry standards and tolerances, ensuring proper fit and performance. Whether for new installations or maintenance and repair projects, these fittings offer versatility and reliability across various piping systems.
Monel K500 Pipe Fittings are known for their high tensile strength, excellent fatigue resistance, and good thermal stability. They maintain structural integrity under high-pressure conditions and resist deformation over time. These mechanical properties make Monel K500 an ideal choice for critical applications in oil and gas, marine engineering, and chemical processing where both strength and corrosion resistance are required.
Monel K500 fittings offer high tensile strength, typically ranging from 690–860 MPa, with yield strength around 380–550 MPa. Elongation usually varies between 20–35%, providing a balance of ductility and toughness. These properties make K500 fittings suitable for high-pressure piping and demanding mechanical applications.
Monel K500 exhibits outstanding corrosion resistance in both oxidizing and reducing environments. It resists pitting, crevice corrosion, and stress corrosion cracking, even in chloride-rich conditions such as seawater. This makes K500 fittings suitable for marine systems, chemical plants, and offshore pipelines where corrosion resistance is critical.
