摘要
通过对X80级管线钢不同方向拉伸性能、金相硬度、金相组织的试验和分析,得出了X80级管线钢的各向异性特征:横向强度大于纵向强度,纵向韧性优于横向韧性。并对该特征进行了分析讨论。
It educes anisotropy characteristic of grade X80 steel: transverse strength is greater than longitudinal strength and longitudinal toughness is superior to transverse toughness by test and analysis of different direction of tensile property,metallurgical hardness and metallurgical structure of grade X80 pipeline steel and it analyses and discusses its characteristic.
