    AI Overview
    AISI 1566 is a high-carbon, high-manganese (0.60–0.70% C, 0.85–1.15% Mn) alloy spring steel known for high hardenability, excellent fatigue resistance, and good elasticity. Often equivalent to Chinese 65Mn, it is used for flat/round springs, agricultural machinery (plough shares), and industrial shafts. It is suitable for hardening and tempering, offering a durable balance of strength and toughness. 
    Key Characteristics & Properties 
    • Composition: High-carbon steel with increased manganese (0.85–1.15%) compared to 1060 series, which enhances hardenability.
    • Mechanical Properties: High tensile strength (typically
      ≥980is greater than or equal to 980
      ≥980
       MPa) and good elasticity.
    • Hardness: Hardens to a martensitic surface, often used in quenched-and-tempered conditions for max toughness.
    • Density:
      7.85
      g/cm3
       (0.284
      lb/in3lb/in cubed
      lb/in3
      ).
    • Weakness: Sensitive to overheating, with a tendency to form quenching cracks and moderate decarburization risk. 
    Common Applications 
    • Springs: Flat springs, cushion springs, and small coil springs.
    • Industrial Components: Shafts, hard tools, and wear-resistant machinery parts.
    • Blades: Used in sword making for its toughness, often and differential heat-treated. 
    Equivalent Standards 
    • China: 65Mn (Commonly quoted equivalent).
    • Japan: SUP3. 
    Processing Notes
    AISI 1566 is hard to weld with conventional gas or arc methods, requiring specialized techniques like Thermit welding. It is known for its excellent performance in high-abrasion environments.
