Maraging 250 / Maraging C250 / Vascomax C250™
(UNS K92890)
Maraging 250™ (also
referred to as Maraging C250™ 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). |
