AISI 9310
It is widely used in forged components subjected to heavy loads, fatigue, and impact, particularly in aerospace, defense, and industrial applications.
Descriptions
1. Chemical Composition
The chemical composition of AISI 9310 is optimized for hardenability and durability. Key elements are listed below:
| Element | Composition (% by Weight) |
| Carbon (C) | 0.08-0.13 |
| Manganese (Mn) | 0.45-0.65 |
| Silicon (Si) | 0.15-0.35 |
| Nickel (Ni) | 3.00-3.50 |
| Chromium (Cr) | 1.00-1.40 |
| Molybdenum (Mo) | 0.08-0.15 |
| Phosphorus (P) | ≤0.025 |
| Sulfur (S) | ≤0.025 |
| Iron (Fe) | Balance |
2. Mechanical Properties
AISI 9310 exhibits excellent mechanical properties after heat treatment (e.g., quenching and tempering). Typical values for forgings are:
| Property | Annealed Condition | Quenched & Tempered |
| Tensile Strength (MPa) | 620-860 | 1030-1240 |
| Yield Strength (MPa) | 380-620 | 930-1070 |
| Elongation (%) | 15-25 | 10–15 |
| Reduction in Area (%) | 45-60 | 35-50 |
| Hardness (HRC) | 12-22 | 32-40 |
| Impact Toughness (J,at20℃) | 40-60 | 25-40 |
3. Key Advantages
Superior fatigue strength for cyclic loading.
Good machinability in annealed condition.
Responsive to case hardening (e.g., carburizing) for enhanced surface wear resistance.
