Description
VCNMO150 is a heat treatable, low alloy steel containing nickel, chromium and molybdenum. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength. A very popular, versatile steel. It can be heat-treated to produce a wide range of tensile strength in moderate sections.
Applications
Typical applications are for structural use, such as aircraft landing gear, power transmission gears and shafts and other structural parts, general engineering parts, hrough-hardened gears, connecting rods and bolts, gun barrels.

.
Normalizing
Normalizing temperature: 850-880oC.
Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650oC, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Hardening
Harden from a temperature of 830-860oC followed by oil quenching. Qenching temperature in the end-quench test is 850oC.
Tempering
Tempering temperature: 540-660oC.

Forging
Hot forming temperature: 1100-900oC.
Machinability
Machining is best done with this alloy in the annealed or normalized and tempered condition. It can be machined by all conventional methods.
Corrosion Resistance
This is a low alloy steel and not a corrosion resistant alloy. Protective coating should be used.
Welding
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 VCNMO150 alloy may be cold worked, in the annealed condition, by conventional methods and tooling. It has good ductility.
