C350 Maraging Steel

C350 maraging steel is a high strength steel alloy containing 2.0% cobalt and 4.8% molybdenum.

Produced by vacuum arc re-melting and providing a very high strength nominally 350 Ksi tensile (2415 MPa) with an above-average level of toughness, the alloy retains its tensile strength up to 450°C and good notch impact is maintained down to minus 50°C and below. This material may be nitrided. We supply C350 in the annealed condition where the microstructure consists of fine martensite before final heat treatment.

Machining & Welding

Maraging steels are usually machined in the annealed condition, although machining in the maraged state is possible. Processing the material close to finished dimensions is also a benefit, as the low-temperature maraging treatment results in minimal distortion. The alloy offers good weldability.

Applications

The alloy is suitable for use in the following areas:

  • High-performance motorsport components
  • Missile Casings
  • Tooling
  • Ordnance mounting blocks
  • Aircraft engine and helicopter driveshafts
