Maraging Alloy 300

Maraging 300 (or Maraging c300) is a vacuum induction melted plus vacuum arc remelted, low-carbon, nickel-cobalt-molybdenum high temperature alloy. Maraging 300 is capable of attaining yield strengths in excess of 270 ksi (1862 MPa) through simple, low temperature heat treatment at 900°F (482°C). Maraging c 300 exhibits good ductility at high strength levels, excellent notch ductility and is readily welded. Maraging 300 is one of a family of Maraging steels which is martensitic yet ductile in the solution treated condition and attains ultra-high strength through a single low temperature aging treatment.
