📘 Technical Specifications: The AMS 6345 Engineering Profile

AMS 6345 dictates the rigorous aerospace requirements for flat-rolled aircraft-quality 4130 alloy steel (UNS G41300). The specific combination of Chromium and Molybdenum delivers excellent hardenability and wear resistance. Because of its nominal 0.30% carbon content, it exhibits outstanding weldability using standard TIG or MIG processes (often welded with ER80S-D2 or 4130 filler rod). When supplied as a Normalized sheet, it provides structural engineers the perfect balance of yield strength, elongation, and impact resistance without the immediate need for complex post-machining heat treatments.

Metallurgical Composition & Purity Limits

ElementTarget (%)Effect
Carbon (C)0.28 - 0.33Maintains weldability while allowing hardening
Chromium (Cr)0.80 - 1.10Increases hardenability and wear resistance
Molybdenum (Mo)0.15 - 0.25Maintains strength and improves hardenability
Manganese (Mn)0.40 - 0.60Deoxidizer, contributes to strength
Silicon (Si)0.15 - 0.35General deoxidizer

Sulfur and Phosphorus are strictly limited to max 0.025% (Aircraft Quality limits) to prevent brittleness and cracking during precision sheet metal welding operations.

Typical Mechanical Properties (Normalized Sheet)

PropertyThickness RangeValue
Tensile Strength (UTS)Under 0.187"~ 95,000 psi (655 MPa)
Tensile Strength (UTS)0.187" to 1.500"~ 90,000 psi (620 MPa)
Yield Strength (0.2%)Under 0.187"~ 75,000 psi (517 MPa)
Yield Strength (0.2%)0.187" to 1.500"~ 70,000 psi (482 MPa)
Elongation in 2 inchesTypical10.0% - 16.0%

While supplied in the Normalized condition for excellent formability, AMS 6345 can be quenched and tempered by the end-user to reach ultimate tensile strengths up to 150,000 psi if required for structural brackets.

AMS 6345 Cross-Reference & Global Equivalents
