NiMark® 250 is a low-carbon, nickel-cobalt-molybdenum high-temperature alloy capable of attaining yield strengths in excess of 240 ksi (1655 MPa) through a simple, low temperature heat treatment. It exhibits good ductility at high strength levels and is readily welded.
NiMark® 250 is one of a family of "maraging" nickel steels which is martensitic yet ductile in the solution treated condition and attains ultra-high tensile strength by aging at temperatures in the range of 850/950°F (454/510°C).
