Characteristics: Monel is a high tensile strength nickel-copper alloy that was discovered in 1905. It was found to be highly resistant to atmospheric corrosion, salt water, as well as various acid and alkaline solutions. Alloy 400 can be magnetic depending upon composition and previous work history. Alloy K-500 has added aluminum and titanium for age hardening. It is totally nonmagnetic and spark resistant.
Uses: K-500 is used for gyroscope application and anchor cable aboard minesweepers. It is also used for propeller shafts on a wide variety of vessels and exhibits high fatigue strength in seawater. There is also application in chemical process applications for handling of organic acids, caustic and dry chlorine.
Monel 400 is used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.
