Our Monel K500 Buttweld Fittings are made up of about 67% nickel and 28–29% copper, with a touch of aluminum and titanium for that extra strength through precipitation hardening. This age-hardened nickel-copper alloy boasts significantly higher strength and hardness compared to Monel 400, featuring a tensile strength of around 830 MPa and remarkable resistance to corrosion, erosion, and stress-corrosion cracking. Plus, it maintains excellent mechanical properties even in sub-zero temperatures. With its superior fatigue resistance and toughness, this alloy is perfect for high-stress and high-pressure applications in chemically aggressive settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
