Monel plates are highly regarded for their exceptional corrosion resistance and superior strength in demanding environments. Om Steel, a reputable stainless steel manufacturer, offers a comprehensive range of Monel plates to meet the diverse requirements of various industries.
Our Monel plates are available in different grades, including Monel 400 and Monel K500. Monel 400 exhibits excellent resistance to corrosive media such as seawater, acids, and alkalis. It is commonly used in marine, chemical, and offshore industries. Monel K500 offers enhanced strength and hardness, making it suitable for high-stress applications in extreme environments.
The features of our Monel plates include excellent weldability, good thermal conductivity, low coefficient of thermal expansion, and exceptional mechanical properties. They provide long-lasting performance, even in harsh conditions, making them ideal for applications in aerospace, oil and gas, and chemical processing industries.
At Om Steel, we prioritize quality and adhere to stringent manufacturing processes to ensure the highest standards are met. Our experienced team is committed to delivering Monel plates that meet or exceed customer expectations.
Equivalent Grades of
Monel Cold Rolled Plates
Monel 400
One of the most popular grades of Monel cold rolled sheets is Monel 400. This grade contains approximately 67% nickel and 23% copper. It also has small amounts of iron, manganese, carbon, and silicon. Monel 400 offers excellent resistance to seawater corrosion and stress-corrosion cracking in freshwater environments. It is also resistant to sulfuric acid, hydrofluoric acid, and alkaline solutions.
Monel K500
Another grade of Monel cold rolled sheets is Monel K500. This grade contains approximately 63% nickel and 30% copper with small amounts of aluminum and titanium. Compared to Monel 400, it has higher strength and hardness due to its age-hardening process. However, it has lower corrosion resistance than Monel 400 in some environments.
Monel 404 (UNS N04404)
Monel 404 is an alloy that contains copper, nickel, iron, manganese, silicon, carbon, and sulfur. It has good corrosion resistance properties in seawater but lower mechanical properties than Monel 400.
