一种B级抗酸管线钢板及生产工艺
摘要：
本发明公开了一种B级抗酸管线钢板，其化学成分及质量百分比如下：C：0.010%～0.040%、Si：0.10%～0.30%、Mn：0.80%～0.90%、P≤0.015%、S≤0.0010%、Ni:0.10%～0.20%、Cu:0.10%～0.20%、Nb：0.020%～0.040%、Mo:0.08%～0.15%、Ti：0.010%～0.020%、Ca：0.001%～0.003%、Al：0.010%～0.040%、余量为Fe和不可避免的杂质，Ceq：0.16～0.23%，Pcm：0.07～0.13%。本发明使用少量Nb合金元素，Mo元素进行退税处理，有效降低了生产成本，满足产品抗酸耐腐蚀性能要求。
摘要（英）：

The invention discloses a B-grade anti-acid pipeline steel plate. The chemical composition of the B-grade anti-acid pipeline steel plate comprise the following in mass percentage: 0.010-0.040% of C, 0.10-0.30% of Si, 0.80-0.90% of Mn, no more than 0.015% of P, no more than 0.0010% of S, 0.10-0.20% of Ni, 0.10-0.20% of Cu, 0.020-0.040% of Nb, 0.08-0.15% of Mo, 0.010-0.020% of Ti, 0.001-0.003% of Ca, 0.010-0.040% of Al, the balance Fe, inevitable impurities, 0.16-0.23% of Ceq, and 0.07-0.13% of Pcm. The invention uses a small amount of Nb alloy element, the tax refund treatment is conducted on the Mo element, the production cost is effectively reduced, and the product anti-acid corrosion resistance requirements are met.
