Aerospace & Energy Materials Dept.

Main Features

MA23 is a nickel-chrome-tungsten-molybdenum alloy, key features of which are great oxidation resistance in temperatures up to 1,150°C, excelent high-temperature strength , and excellent stability after long hours of heating. Good resistance to nitriding is also one of its characteristics. MA23 is most suitable for burning tubes of gas turbines, liners, heating furnaces, and as high-temperature materials used by the chemical industry.

Available Product Forms

Various shapes, such as flat-rolled plates, forgings, welding wires, wires, welded pipes and tubes, seamless pipes and tubes can be manufactured.
