ASTM B127 Monel 400 Plate
Monel 400 is a corrosion-resistant nickel-copper alloy containing approximately 67% nickel and 23% copper. It exhibits excellent mechanical properties across a wide temperature range (-200°C to +600°C) and outstanding resistance to seawater, acids, and alkaline solutions. This alloy is particularly valued for marine engineering and chemical processing applications.
