Research on the Influence of Different Charging Mode on Microstructure and Properties of X70 Pipeline Steel
摘要
Abstract
The influence of different charging mode on the microstructure and properties of 17.5 mm X70 pipeline steel were researched in this paper. Adopting optical microscope and transmission electron microscope and other inspection method to conduct compare and analyze the properties of 17.5 mm X70 pipeline steel hot rolling coil from several aspects,such as microstructure,relative quantity,mechanical properties and etc. The result showed although the microstructure of hot rolled coil exist tiny distinction,the mechanical properties under cold charging and hot charging mode reach the same technical target and can meet technical requirements of the user.关键词
