The effects of annealing temperature on microstructure and hardness of hot-dip galvanized low alloy high strength steel strip HC420LAD+Z are analyzed through thermal simulated test machine, optical microscope and hardness test as well as it is concluded that its recrystallization temperature is 700 ℃. The changes of microstructure and properties of the steel strip at different annealing temperatures are further discussed combining the industrial productions with the measured recrystallization temperature. The results showed that the mechanical properties of steel strip were the best when annealed at 780 ℃, yield strength was 467 MPa, tensile strength was 508 MPa, elongation was 24% and the surplus was moderate, which could meet the requirements of EN 10346-2015 standard and customer use.

通过热模拟试验机、光学显微镜以及硬度试验分析了退火温度对热镀锌低合金高强钢带HC420LAD+Z组织和硬度的影响,得出HC420LAD+Z钢带的再结晶温度为700 ℃。工业生产结合测得的再结晶温度进一步讨论了退火温度不同时钢带的组织以及性能的变化,结果表明,780 ℃退火时钢带的力学性能最优,屈服强度为467 MPa,抗拉强度为508 MPa,伸长率为24%,富余量适中,满足EN 10346—2015标准和用户使用要求。
