Abstract

本发明公开了一种低合金高性能钢，其合金成分包含质量百分比为0.48%的铬、0.13%的钛、0.056%的钒、0.08%的硼，且经过终轧温度为850摄氏度、卷曲温度为650摄氏度，冷却速度为11OC/s后成型。本发明提供的一种低合金高性能钢，因其含有特定比例的微合金元素与制备工艺结合，因此具有较高的屈服强度、抗拉强度好延伸率，实验时，其延伸率能提高24.36%，完全满足汽车用高强度钢的性能要求。

Description

一种低合金高性能钢
技术领域
本发明涉及合金钢技术领域,尤其涉及一种低合金高性能钢。
背景技术
通常情况下，汽车用高强度合金钢都需要经过热压加工后成型使用，热加工过程中钢材的组织性能发生变化（如动态/静态回复与再结晶等等），不同的合金元素及加热工艺对其钢材的热变行为会产生影响，从而直接影响钢材的性能。
