Grade C200 Maraging SteelGrade C200

Maraging Steel

C200 - a maraging alloy steel containing 8.5% cobalt and 3.3% molybdenum.

This steel is produced by vacuum arc re-melting to provide high strength although this is still low when compared with other maraging steels, nominally 200 ksi tensile (1380 MPa) 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. C200 is usually supplied in the annealed condition where the microstructure consists of fine martensite before final heat treatment.

Machinability & Welding:

Maraging steels are usually machined in the annealed condition, however, they can be machined in the maraged condition. Components can be machined close to finished dimensions as the low temperature maraging treatment results in minimal distortion. In addition, the small contraction of approximately 0.05% due to maraging results in good dimensional stability.

C200 steel has good weldability.
