Superior Quality ASTM B564 Monel k500 Orifice Flange and Slip On Flange at competitive prices.

Monel K500 is a precipitation-hardenable nickel-copper alloy with similar corrosion resistance properties to Monel 400, but with added strength and hardness due to the precipitation hardening process. Flanges made from Monel K500 offer enhanced mechanical properties while retaining excellent corrosion resistance, making them suitable for a wide range of demanding applications.

Monel K500 flanges are particularly valued in industries where high strength, corrosion resistance, and reliability are paramount. These flanges exhibit excellent resistance to a variety of corrosive environments, including seawater, acids, alkalis, and high-velocity seawater. This resistance makes them highly suitable for marine, offshore, chemical processing, and oil and gas applications.
