📘 Technical Specifications: The AMS 6415 Engineering Profile
AMS 6415 dictates the rigorous requirements for air-melted 4340 alloy steel (UNS G43400). Its deep hardenability comes from the precise combination of nickel (up to 2.0%), chromium (up to 0.90%), and molybdenum (up to 0.30%). Unlike basic carbon steels that lose toughness as strength increases, 4340 retains exceptional ductility and resists embrittlement even when heat-treated to extremely high tensile levels. AMS 6415 ensures tighter chemical and macrostructure controls compared to standard commercial 4340 grades, ensuring reliability in dynamic loading applications.
Metallurgical Composition & Purity Limits
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | 0.38 - 0.43 | Provides base hardness and strength |
| Nickel (Ni) | 1.65 - 2.00 | Delivers toughness and deep hardenability |
| Chromium (Cr) | 0.70 - 0.90 | Improves wear resistance and hardness |
| Molybdenum (Mo) | 0.20 - 0.30 | Maintains strength at elevated temperatures |
| Manganese (Mn) | 0.60 - 0.80 | Deoxidizer, contributes to strength |
| Silicon (Si) | 0.15 - 0.30 | General deoxidizer |
Sulfur and Phosphorus are limited to max 0.025% to prevent brittleness and improve transverse ductility.
Typical Mechanical Properties (Heat Treated)
| Property | Value | Unit |
|---|---|---|
| Ultimate Tensile Strength (UTS) | 1240 - 1380 (180,000 - 200,000) | MPa (psi) |
| Yield Strength (0.2% Offset) | ≥ 1100 (160,000) | MPa (psi) |
| Elongation in 2 inches | ≥ 10.0 | % |
| Reduction of Area | ≥ 35.0 | % |
| Hardness (Typical Tempered) | 26 - 40 | Rockwell C (HRC) |
While the material can be heat-treated to higher strengths (up to 260 ksi), it is typically utilized in the 180-200 ksi range to maximize fatigue life. Our stock is usually supplied Annealed (max 235 HB) for easy rough machining.
