一位设计者在为使用高合金工具钢（如SKD11）制作的模具零件时，错误地指示了“HNR”（热作锻模钢），这是对碳钢的一种热处理方式。SKD11含有较多合金成分，具有“空冷硬化性”，即使是空气冷却也会发生淬火。结果，经过正火处理的零件变得非常坚硬，导致后续的切削加工完全无法进行。这个零件最终被报废，不仅浪费了材料费和热处理费，还造成了交货期严重延误。

- 该工艺由“加热”、“保持”和“冷却”三个步骤组成。
- 加热温度根据钢的碳含量，设定为比A3点或Acm点高约50℃
- 空冷实现晶粒细化的关键是冷却速度
- 晶粒细化会提高强度和韧性
- S45C等碳钢的抗拉强度、屈服点和伸长率得到改善
- 低炭素鋼では適度な硬さが得られ被削性が向上する
- 淬火前进行预处理，可以显著抑制淬火时的变形。
- 优点包括质量稳定、性能提升、加工性改善、变形抑制等
- 缺点是成本增加、材料限制、尺寸影响、氧化皮生成
- 高合金钢因易于空冷硬化，因此不适合退火。
- 图纸说明中应明确标注JIS符号“HNR”。
