42CrMo4V Alloy Steel Forgings
- Material Composition: 42CrMo4V steel with enhanced chromium-molybdenum-vanadium properties for superior hardenability and fatigue resistance.
- Manufacturing Process: Electro Arc Furnace (EAF), Ladle Refining (LF), Vacuum Degassing (VD), and precision hot forging.
- Mechanical Performance: Excellent tensile strength, yield strength, and impact toughness for high-stress industrial environments.
- Surface Quality: Achieves a smooth finish with a surface roughness up to Ra 0.4 µm, ensuring precision fitting and minimal friction loss.
- Dimensional Accuracy: Tolerances held within ±0.01 mm through CNC-controlled machining and measurement.
