Heat Treatment:
- Normalizing: Heated to 850–900°C, followed by air cooling to refine grain structure.
- Quenching: Heated to 880–920°C, quenched in oil or water to improve hardness and strength.
- Tempering: Performed at 200–400°C after quenching to relieve internal stresses and enhance toughness.
- Annealing: Heated to 650–700°C to improve machinability and reduce hardness.
Applications:
- Automotive Industry: Gears, shafts, and connecting rods subjected to dynamic loading.
- Aerospace: High-strength components requiring wear resistance.
- Heavy Machinery: Shafts, bearings, and other parts experiencing mechanical stress.
- Tool Manufacturing: Tools and dies with high wear resistance requirements.
- Oil and Gas: Components like drill collars and couplings exposed to heavy wear.
Corrosion Resistance
15VDC6 offers moderate corrosion resistance due to its alloying elements, such as chromium and vanadium. For enhanced corrosion protection, it is often surface-treated or coated e.g., nitriding, galvanizing, or painting.
