Key Features and Properties
AISI 4140 Alloy Steel combines strength, hardness, and machinability, making it suitable for high-stress mechanical applications.
Here’s what makes it stand out:
- High tensile and yield strength for structural integrity
- Excellent wear and impact resistance under dynamic loads
- Good fatigue strength for long-term performance
- Uniform hardness and toughness after heat treatment
- Machinable and weldable with appropriate precautions
4140’s chromium content enhances corrosion resistance, while molybdenum improves hardenability and toughness — making it a preferred choice in demanding environments.
