High Strength Alloy 30CrMo Round Bar
30CrMo Round Bar Products Components
The chemical composition of 30CrMo round bar mainly includes the elements of carbon (C), silicon (Si), manganese (Mn), chromium (Cr) and molybdenum (Mo). The specific range of its chemical composition is as follows:
- Carbon (C): 0.26 to 0.34%
- Silicon (Si): 0.17 ~ 0.37%
- Manganese (Mn): 0.40 ~ 0.70%
- Chromium (Cr): 0.80 ~ 1.10%
- Molybdenum (Mo): 0.15 ~ 0.25%
- Phosphorus (P): ≤ 0.035%
- Sulfur (S): ≤ 0.035%
- Nickel (Ni): ≤0.030%
- Copper (Cu): ≤0.030%
30CrMo Round Bar Products Details
- High Strength and Toughness: 30CrMo round bar has high strength and good toughness, suitable for withstanding high temperature and high pressure environment.
- Good NMenability: critical quenching diameter in oil is 15 to 70mm, suitable for heat treatment to obtain the required NMness and strength.
- Heat resistance: good high-temperature strength up to 500°C, but a significant drop in strength at 550°C.
- Machinability and weldability: good machinability and weldability, need to be preheated to above 175℃ before welding.
