📘 Technical Specifications: The AMS 6417 Engineering Profile
AMS 6417 precisely governs the specifications for 300M Alloy Steel (UNS K44220) with a slightly broader carbon control compared to AMS 6419. Based heavily on 4340 steel, 300M incorporates a significantly higher silicon content. This silicon addition retards the formation of embrittling carbides during tempering, allowing the steel to be tempered at higher temperatures. This yields exceptional fracture toughness while retaining a massive core tensile strength of ~270 ksi minimum. The addition of vanadium acts as a powerful grain refiner, further enhancing the alloy's structural integrity.
Metallurgical Composition & Purity Limits
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | 0.37 - 0.43 | Primary matrix hardener |
| Silicon (Si) | 1.45 - 1.80 | Prevents temper embrittlement |
| Nickel (Ni) | 1.65 - 2.00 | Provides deep hardenability and toughness |
| Chromium (Cr) | 0.70 - 0.95 | Improves wear resistance and hardenability |
| Molybdenum (Mo) | 0.30 - 0.50 | Enhances high-temperature strength |
| Vanadium (V) | 0.05 - 0.10 | Refines grain structure, boosts yield |
| Manganese (Mn) | 0.65 - 0.90 | Deoxidizer and strengthening agent |
Sulfur and Phosphorus are strictly limited to prevent stress-corrosion cracking and fracture propagation.
Mechanical Properties (Hardened & Tempered)
| Property | Value | Unit |
|---|---|---|
| Ultimate Tensile Strength (UTS) | 1860 - 2035 (270,000 - 295,000) | MPa (psi) |
| Yield Strength (0.2% Offset) | ≥ 1515 (220,000) | MPa (psi) |
| Elongation in 4D | ≥ 8.0 | % |
| Reduction of Area | ≥ 30.0 | % |
| Hardness (Heat Treated) | 52 - 55 | Rockwell C (HRC) |
Our AMS 6417 bars are typically supplied in the Normalized & Tempered condition (max 311 HB) to facilitate CNC machining before final heat treatment by the customer.
AMS 6417 Cross-Reference & Global Equivalents
300M Alloy is referenced under multiple global designations depending on the specific melting practice and final condition. AMS 6417 dictates the premium aircraft-quality standard for consumable electrode vacuum-melted bars and forgings.
