Kanakratna steelage is a renowned exporter, manufacturer, stockist, supplier, and stockholder of high-quality Monel Alloy Seamless Tubes. These nickel-copper alloy tubes are celebrated for their excellent corrosion resistance and high strength, making them ideal for marine, chemical, hydrocarbon processing, and oil and gas applications. Monel alloy tubes maintain their strength and toughness across a wide temperature range and offer excellent weldability and ease of fabrication.
Alloy 400 (UNS N04400) is a solid-solution Nickel/Copper alloy that can be hardened only by cold working. It has reasonable strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.
Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and freshwater tanks; crude petroleum stills, process vessels and piping; boiler feedwater heaters and other heat exchangers; and deaerating heaters
