Maraging Steel 200

Maraging steel is produced by vacuum arc re-melting to provide a lower impurity level and high strength, although lower in comparison to other maraging steels, maraging 200 in the aged condition boasts more than 200 ksi tensile (1380 MPa) with similar yield results, a nominal 12% elongation and 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.

Maraging 200 is usually supplied in the annealed condition where the microstructure consists of fine martensite before final heat treatment. Maraging steels are exceptionally stable during both annealing and aging, offering predictable, uniform shrinkage on all dimensions. This distortion-free (nonwarping) characteristic is a significant advantage over many other high-strength steels. The essential difference between the C-type and T-type maraging steels is the chemical analysis. In terms of mechanical properties and recommended processing there are few, if any, significant differences. Nickel, rather than carbon, is the principle element in maraging steels, which are essentially carbon-free.
