📘 Technical Specifications: The AMS 6512 Engineering Profile
AMS 6512 specifically mandates the requirements for Maraging 250 steel (UNS K92890). Compared to Maraging 300, Grade 250 contains slightly lower titanium and cobalt. This intentional metallurgical adjustment results in a steel that still boasts a massive yield strength (250 ksi) but significantly increases ductility and fracture toughness. Because it is virtually carbon-free, parts can be machined in the soft annealed condition and then age-hardened (precipitated) at 900°F (480°C) with negligible dimensional distortion, eliminating the need for post-machining grinding.
Metallurgical Composition & Purity Limits
| Element | Target (%) | Effect |
|---|---|---|
| Nickel (Ni) | 17.0 - 19.0 | Forms the tough, high-ductility matrix |
| Cobalt (Co) | 7.0 - 8.5 | Accelerates aging, enhances strength |
| Molybdenum (Mo) | 4.6 - 5.2 | Primary precipitation hardener |
| Titanium (Ti) | 0.3 - 0.5 | Forms intermetallic precipitates (lower than 300) |
| Carbon (C) | 0.03 Max | Kept intentionally low for toughness/weldability |
| Iron (Fe) | Remainder | VIM+VAR remelted for supreme purity |
Sulfur and Phosphorus are strictly limited to ≤ 0.01% to prevent fracture propagation in highly stressed aerospace components.
Mechanical Properties (After Aging at 900°F)
| Property | Value | Unit |
|---|---|---|
| Ultimate Tensile Strength (UTS) | ≥ 1758 (255,000) | MPa (psi) |
| Yield Strength (0.2% Offset) | ≥ 1724 (250,000) | MPa (psi) |
| Elongation in 4D | ≥ 8.0 | % |
| Reduction of Area | ≥ 40.0 | % |
| Hardness (Aged) | 48 - 52 | Rockwell C (HRC) |
Supplied in the Solution Annealed condition (approx 30-35 HRC) to allow for easy CNC machining, broaching, and threading prior to the final aging cycle.
