摘要:
介绍了基于应变设计的X80和X100大变形高强管线钢的合金化设计及最佳工艺过程。研究了壁厚为15 mm,22 mm的X80管线钢管和壁厚为16 mm,20 mm的X100管线钢管在热时效(240 ℃)前后的力学性能、DWTT压制缺口试样性能以及微观组织构成。结果表明,X80和X100管线钢在热时效(240 ℃)后均表现出优越的可变形性;良好弥散的铁素体贝氏体双相微观组织构成可以使管线钢具有优越的低温韧性和塑性变形能力。工厂已经生产出了在热时效后具有优越的可变形性和低温韧性的X80和X100管线钢管。
Abstract:
This paper introduces the strain-based design of grade X80 and X100 steel large deformation, high strength pipeline steel alloying design and the optimum technological process. Detailed study of the wall thickness is 15 mm and 22 mm X80 pipeline steel pipe and wall thickness to 16 mm, 20 mm X100 pipeline steel pipe, before and after thermal ageing (240 ℃), the mechanical properties of press-notched DWTT performance and microstructure. The results show that X80 and X100 pipeline steel after thermal ageing (240 ℃) showed excellent deformability; A fine dispersive dual-phase microstructure is also effective for improving plastic deformation behavior as well as low-temperature toughness. The factory has produced, after thermal aging, excellent deformability and low temperature toughness of X80 and X100 pipeline steel pipe.
