摘要

通过使用氢淬火连续退火技术，Stelco股份有限公司开发了一套拉伸强度大于1000MPa的高级高强度钢（AHSS）等级，以满足标准汽车规范和独特的客户要求。通过将化学成分和工艺参数与微观结构和机械性能相关联，对这些等级进行了优化。双相980（Stelco商标STELMAXTM 980DP）、多相1180（STELMAXTM1180MP）、马氏体钢1300（STELMEXTM1300M）和1500（STELMXTM1500M）产品满足强度和成形性要求，具有优异的平面度和表面质量。氢淬火连续退火技术不仅确保所有开发的AHSS等级在整个带钢长度（从带钢头到带钢尾）和宽度（从带钢边缘到带钢边缘）上具有一致的机械性能，而且与其他连续退火工艺相比，产品产量也很高。

Development of advanced high strength steels using hydrogen quench continuous annealing technology

By using hydrogen quench continuous annealing technology, Stelco Inc. has developed a suite of Advanced High Strength Steel (AHSS) grades with tensile strength greater than 1000MPa to meet standard automotive specifications and for unique customer requirements. These grades were optimized by correlating chemical composition and processing parameters with microstructures and mechanical properties. Dual-Phase 980 (Stelco trademarked STELMAXTM 980DP), Multi-Phase 1180 (STELMAXTM 1180MP), Martensitic Steel 1300 (STELMAXTM 1300M) and 1500 (STELMAXTM 1500M) products met strength and formability requirements with excellent flatness and surface quality. Hydrogen quench continuous annealing technology not only ensures all developed AHSS grades have consistent mechanical properties across the entire strip length (from strip head to tail) and width (from edge to edge), but also produces high product yield compared with other continuous annealing processes.
