4140 Alloy Steel (Chromium-Molybdenum Steel)
4140 is a low-alloy steel known for high tensile strength, good toughness, and wear resistance. It performs well in demanding mechanical environments and is suitable for both machining and stamping.
| Tensile Strength | Elongation at Break | Hardness | Desnsity |
|---|---|---|---|
| 655–950 MPa | 20–25% | 200–300 HB | 7.85 g/cm³ |
4340 Alloy Steel (Nickel-Chromium-Molybdenum Steel)
4340 offers ultra-high strength, excellent toughness, and superior fatigue resistance. It is often chosen for critical components that require durability under high stress.
| Tensile Strength | Elongation at Break | Hardness | Desnsity |
|---|---|---|---|
| 745–1180 MPa | 18–22% | 217–302 HB | 7.85 g/cm³ |

Is alloy steel suitable for machining and stamping?
Yes. Alloy steels such as 4140 and 4340 are commonly used for CNC machining and stamping. They offer good dimensional stability and can achieve tight tolerances.
Does alloy steel need surface treatment to prevent corrosion?
Most alloy steels are not naturally corrosion-resistant and usually need coatings like plating, painting, or heat treatment to improve durability in harsh environments.
Can Zhongde produce custom alloy steel components based on my drawings?
Yes. We can manufacture prototypes or high-volume alloy steel parts according to your 2D drawings or 3D models, ensuring precise dimensions and consistent quality.
