Description
VCV150 is a heat treatable, low alloy steel containing manganese, chromium and vanadium. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength.
Applications
Permanently stressed machine, engine and vehicle parts when high strength and toughness are required.Most severely stressed springs for trucks, torsion springs.

Forger
Température de formage à chaud: 1050-850oC.
Usinabilité
Machining is best done with this alloy in the annealed or normalized and tempered condition. It can be machined by all conventional methods.
Résistance à la corrosion
This is a low alloy steel and not a corrosion resistant alloy. Protective coating should be used.
Soudage
The alloy can be fusion or resistance welded. Preheat and post heat weld procedures should be followed when welding this alloy by established methods.
Cold working
The VCV150 alloy may be cold worked, in the annealed condition, by conventional methods and tooling. It has good ductility.
