Product Description
Maraging Steel C300(AMS 6514, AMS 6521)
Type C300 cobalt containing grade of maraging steel, produced by vacuum arc re-melting, provides very high strength (nominally 300 ksi tensile) with an above average level of toughness. The alloy retains its strength up to 450°C and good notch impact is maintained down to minus 50°C and below. This material may be nitrided. C300 is usually supplied in the annealed condition where the microstructure consists of fine martensite. This structure is then maraged (precipitation hardened) to achieve final properties employing a relatively low temperature that results in the required combination of high strength and toughness. The alloy has a density of 8.02 g/cc.
