近日,东大RAL与本钢集团合作,成功开发出超高强PHS1 500冷轧退火热冲压成形钢,并在国内某专业冲压技术公司成功完成零部件热冲压试验。此次试制的零部件为国产某品牌高档轿车的B柱,产品合格率达到100%,且表面质量和尺寸精度良好,性能一致性优异。零件底部和侧壁取样屈服强度均到达1 240 MPa,抗拉强度达到1 580 MPa。该钢种的成功研发应用填补了本钢集团汽车板此类产品的空 Recently, Dongda RAL and Benxi Iron and Steel Group, the successful development of ultra-high PHS1 500 cold-rolled annealing hot stamping steel, and a professional stamping technology company successfully completed the hot stamping parts. The trial of components for a domestic brand of luxury cars B-pillar, the product pass rate of 100%, and the surface quality and dimensional accuracy, excellent performance consistency. The yield strength at the bottom and sidewall of the part reached 1 240 MPa and the tensile strength reached 1 580 MPa. The success of the steel research and development applications to fill the Bengang Group automobile plate empty of such products
