Bright Surface Stainless Round Bar AMS 6512 MIL-S-46850 ASTM A538 Maraging 250
Maraging 250 is a tough, relatively soft and therefore readily machined and formed. Full properties achieved through martensitic precipitation aging. Full Maraging 250 is part of the 18% Nickel Maraging Steel family alongside Maraging 200 and Maraging 300. When taking into consideration Maraging steels, even though some of them contain Cobalt and some Titanium as their strengthening alloy, one must remember that their physical properties are similar. So similar are they that the number in the grade name (250 in this case) corresponds, relatively, not 100% but in most cases, to the tensile strength with most other properties the same.
Usually furnished in the annealed condition Maraging 250 is relatively soft and easy to machine. However after heat treating and via precipitation hardening the hardness increases greatly which makes this steel sufficient for tooling applications.
Maraging Steel 250 is available in Round Bar in AMS 6512 and MIL-S-46850.

Maraging 250™(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.
