High Quality 4130 Steel Round Bar Optimized Chemical Composition - China

Optimization of 4130 steel round bar chemical composition

The chemical composition of 4130 steel round bar has been carefully designed to ensure that it has both high strength and toughness:

- **Carbon (C)**: The right amount of carbon content (0.28-0.33%) provides good strength and hardness while maintaining sufficient toughness.

- **Chromium (Cr)**: The addition of chromium (0.8-1.1%) enhances the steel's corrosion and oxidation resistance, helping to maintain the integrity of the material in high-temperature environments.

- **Molybdenum (Mo)**: Molybdenum (0.15-0.25%) provides additional strength and heat resistance, especially at high temperatures.
