Production method of anti-fatigue steel plate for hydrogen pipeline

The invention discloses a steel plate for an anti-fatigue hydrogen pipeline and a production method of the steel plate. The steel plate comprises the following chemical components in percentage by weight: 0.05-0.10% of C, 0.20-0.30% of Si, 1.00-1.30% of Mn, 0.15-0.35% of Cr, 0.05-0.15% of Nb + V + Ti, less than or equal to 0.015% of P, less than or equal to 0.010% of S and the balance of Fe and inevitable impurity elements. The production method comprises the steps of billet heating, rolling, stacking and tempering heat treatment. The anti-fatigue steel plate for the hydrogen-contacting pipeline is of a ferrite and pearlite double-phase structure, the steel plate structure is uniform, and the good anti-fatigue performance is achieved in the hydrogen pressure environment. 本发明公开一种抗疲劳临氢管道用钢板及其生产方法，钢板的化学成分及其重量百分含量为：C：0.05～0.10%，Si：0.20～0.30%，Mn：1.00～1.30%，Cr：0.15～0.35%，Nb+V+Ti：0.05～0.15%，P≤0.015%，S≤0.010%，余量为Fe和不可避免的杂质元素；其生产方法包括钢坯加热、轧制、堆垛、回火热处理工序。本发明提供的临氢管道用抗疲劳钢板为铁素体+珠光体双相组织，钢板组织均匀，在氢气压力环境下具有良好的抗疲劳性能。
