Maraging 250/Maraging C250/Vascomax C250™ - UNS K92890
Maraging 2507™(also referred to as Maraging C25™ and Vascomax 250™) is a vacuum induction melted plus vacuum arc melted, 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. Maraging 250™ exhibits good ductility at high strength levels and is readily welded.
Maraging C250™ is one of a family of "maraging" nickel steels (including Maraging 300™ and 350™) which are ductile in the solution treated condition and attains ultrahigh tensile strength by aging at temperatures in the range of 850/950 °F (454/510 °C).
Available forms are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.
