预硬钢用英文怎么说
时间：
预硬钢用英语叫做 "prehardened steel"。
预硬钢是通过钢材在较低温度下冷却并固化来获得更高强度和硬度的钢材。这样做的目的是为了使钢材在生产过程中不需要经过热处理，就可以获得较高的强度和硬度。
例句：
"The manufacturer uses prehardened steel to make their tools because it provides greater durabipty and longevity."（制造商使用预硬钢制造工具，因为它提供了更高的耐用性和寿命。）
"Prehardened steel is preferred for many apppcations because it is easier to work with and requires less processing."（预硬钢在许多应用中被首选，因为它更容易加工，并且需要更少的处理。）
"The advantage of prehardened steel is that it can be cut and shaped without losing its strength and hardness."（预硬钢的优点是，它可以切割和成型而不会失去强度和硬度。）
