Grade Monel K500 Pipe Fittings UNS (N05500), DIN (2.4375)
Monel K500 Buttweld Fittings consist of about 63% nickel and 30% copper with a few percentages of aluminum (2.3–3.15%) and titanium (0.35–0.85%). These components contribute to the mechanical strength of the alloy and increase its suitability for stress transfer environments. The alloy offers a combination of tensile strength up to 965 MPa and resistance against corrosion, erosion, and cracking under service conditions in seawater, sour gas, and acidic service environments.
