Monel Alloy: Corrosion-Resistant Monel K-500 Plates for Chemical Processing Equipment

Product Overview

Monel K-500 (UNS N05500) is a precipitation-hardenable nickel-copper alloy renowned for its outstanding strength, corrosion resistance, and non-magnetic properties. By incorporating aluminum and titanium, Monel K-500 achieves higher strength and hardness compared to its predecessor, Monel 400, while maintaining excellent resistance to seawater, acids, and alkalis. This alloy's versatility makes it ideal for demanding applications in marine engineering, aerospace, chemical processing, and oil & gas industries.​

Monel K-500's resistance to corrosion extends across a broad spectrum of environments, including seawater, non-oxidizing acids, and alkalis. Its non-magnetic nature and low permeability are advantageous in applications requiring minimal magnetic interference. The alloy's ability to withstand elevated temperatures, combined with its mechanical strength, ensures reliable performance in harsh conditions.​

In marine environments, Monel K-500 is commonly used for propeller shafts, pump shafts, and valve components. In the oil and gas sector, it serves in downhole tools, drill collars, and safety valves. The alloy's resistance to stress corrosion cracking and fatigue makes it suitable for components subjected to dynamic loading and corrosive media.​
