摘要：
本发明公开了一种酸性环境管道用高韧性A516Gr60薄板及生产方法，所述薄板化学成分组成及其质量百分含量为：C：0.15～0.20%，Si：0.20～0.40%，Mn：0.70～1.20%，P≤0.008%，S≤0.002%，Al：0.020～0.040%，Nb：0.010～0.015%，Mo：0.05～0.12%，Ca：0.0015～0.0030%，O≤0.003%，余量为Fe和不可避免的杂质；所述薄板生产方法包括冶炼、连铸、加热、轧制和热处理工序。本发明酸性环境管道用高韧性A516Gr60薄钢板低温冲击韧性、抗层状撕裂性能和抗氢致开裂性能优良，能够满足酸性环境管道用钢的要求，应用前景广阔。
摘要（英）：

The invention discloses a high-toughness A516Gr60 thin plate for an acid environment pipeline and a production method. Chemical components of the thin plate comprise, by mass percentage, 0.15-0.20% ofC, 0.20-0.40% of Si, 0.70-1.20% of Mn, smaller than or equal to 0.008% of P, smaller than or equal to 0.002% of S, 0.020-0.040% of Al, 0.010-0.015% of Nb, 0.05-0.12% 0f Mo, 0.0015-0.0030% of Ca, smaller than or equal to 0.003% of O and the balance Fe and inevitable impurities. The production method of the thin plate comprises the working procedures of smelting, continuous casting, heating, rolling and heat treatment. The high-toughness A516Gr60 thin plate for the acid environment pipeline has excellent low-temperature impact toughness, layer-shaped tearing resisting performance and hydrogen induced cracking resisting performance, can meet the requirement of steel for the acid environment pipeline, and the application prospect is wide.
