Vascomax C300™ - UNS K93120

Common Trade Names: Vascomax® 300, Maraging C300

Maraging 300® (also referred to as Maraging C300® and Vascomax C300®) is a vacuum induction melted plus vacuum arc re-melted, low-carbon, nickel-cobalt-molybdenum high temperature alloy capable of attaining yield strengths in excess of 270 ksi (1862 MPa) through simple, low temperature heat treatment at 900°F (482°C). Maraging C300® exhibits good ductility at high strength levels. Maraging C-300® also displays excellent notch ductility and is readily welded.

Maraging 300® is one of a family of "maraging" nickel steels such as Maraging 250® & Maraging 350® which are martensitic yet ductile in the solution treated condition and attain ultra-high strength through a single low temperature aging treatment.

Available forms of Maraging 300®  are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.
