When it comes to composition, Monel K500 Pipe Fittings are primarily made up of nickel (around 63%) and copper (28–34%), with the addition of aluminum and titanium to facilitate age hardening. This unique blend results in a significant boost in strength and hardness compared to Monel 400, all while maintaining excellent corrosion resistance. On the mechanical side, these fittings showcase a tensile strength ranging from 830 to 1030 MPa and a yield strength between 380 and 690 MPa, along with outstanding fatigue resistance and non-magnetic characteristics. Monel K500 keeps its mechanical and corrosion-resistant properties intact, whether in sub-zero conditions or at elevated temperatures, making it a go-to choice for severe service applications.

**Monel K500 (UNS N05500)** merges the corrosion resistance of Monel 400 with enhanced strength and hardness thanks to aluminum and titanium precipitation hardening. It excels in resisting stress corrosion cracking, erosion, and pitting, especially in marine and chemical settings. This alloy retains its strength and toughness from sub-zero temperatures all the way up to 650°C. With its high yield strength and non-magnetic characteristics, Monel K500 pipe fittings are perfect for extreme mechanical and corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
