    34CrNiMo6 Steel, SGS approved, EN 10204 3.2 - Otai Special Steel
    34CrNiMo6 (1.6582) is a high-performance, heat-treatable low-alloy steel known for high strength, toughness, and excellent hardenability, commonly used in engineering for heavy-duty components like axles, gears, and engine parts. It is widely used in wind power and aerospace, typically in quenched and tempered (QT) conditions for increased hardness. 
    Key Characteristics: 
    • Material Number: 1.6582 / DIN/EN 34CrNiMo6.
    • Key Properties: Excellent fatigue resistance, high ductility, and good shock resistance at low temperatures.
    • Hardening: Through-hardenability up to ~100 mm diameter (oil quenching).
    • Processing: Readily machinable in softened state, or supplied ready for use (+QT) with tensile strength >1000 N/mm². 
    Chemical Composition (%) 
    • Carbon (C): 0.30–0.38%
    • Chromium (Cr): 1.30–1.70%
    • Nickel (Ni): 1.30–1.70%
    • Molybdenum (Mo): 0.15–0.30%
    • Manganese (Mn): 0.50–0.80% 
    Applications 
    • Automotive/Heavy Machinery: Crankshafts, gears, spindles, connecting rods.
    • Aerospace/Wind Power: High-strength fasteners, landing gear parts, turbine shafts.
    • Tools: Components requiring high fatigue strength and resistance to heavy loads. 
    Heat Treatment Methods 
    • Forging: 850–1100 °C.
    • Normalizing: 860–880 °C, air cool.
    • Hardening: 830–860 °C, oil quench.
    • Tempering: 540–660 °C, air cool. 
    34CrNiMo6 is considered a superior alternative to carbon steels for applications needing high fatigue, impact resistance, and durability under high stress.

    What is the difference between 4340 and 34CrNiMo6?
    Key differences: Carbon content: 4340 has higher carbon content, better hardenability, but slightly lower toughness. Nickel content: 4340 has higher nickel content, which improves low-temperature toughness; 34CrNiMo6 has higher chromium content and slightly better corrosion resistance.
