  • zh含碳量超过0.8%的钢,缓慢冷却后其显微组织除珠光体外还含有渗碳体。它比亚共析钢更硬更脆。

A type of steel that contains more than 0.8% carbon, resulting in a microstructure that includes cementite in addition to pearlite after slow cooling. It is harder and more brittle than hypoeutectoid steel.

  1. High-carbon steel alloyC2formal

    A type of steel with a carbon content greater than 0.77%, which contains cementite in its microstructure in addition to pearlite.

    • Hyper-eutectoid steel is often used for making cutting tools and springs.
    • The microstructure of hyper-eutectoid steel shows a network of cementite around pearlite grains.
    • Heat treatment of hyper-eutectoid steel requires careful control to avoid brittleness.
