摘　　要：本文研究了不同回火工艺对X60管线钢控轧状态性能的影响,从而得出以针状铁素体为主的X60管线钢控轧状态具备良好的强韧性,而回火后韧性降低强度提高。This paper studies the effect of different tempering processes on the properties of X60 pipeline steel plate and concludes that X60 pipeline steel plate mainly with acicular ferrite structure have good strength and toughness properties. It has no significance to decrease toughness and improve strength only by tempering.

关 键 词：管线钢 回火 针状铁素体 强韧性
