摘　　要：采取低碳+低锰+微合金化元素的化学成分设计,通过控制冶炼和控制轧制工艺,降低X52管线钢因成分波动而引起的性能变化。生产的X52管线钢板化学成分在标准要求范围内,轧后组织为铁素体+珠光体,屈服强度402 MPa,抗拉强度550 MPa,-20℃冲击功≥95 J,-20℃DWTT 100%,各项力学性能符合标准要求。The properties variation of X52 pipe line steel caused by componenls fluctuation has been reduced by the smelting and rolling process controlling and the chemical composition design plan of low-carbon ＋ low Manganese ＋ micro-alloying elements. Research results showed that micrnstructure of the X52 pipe line steel plate is ferrite ＋ pearlite, further more, various mechanical properties of the steel plait are in correspondence with standard requirements.
