摘　　要：介绍了低焊接裂纹敏感性07MnCrMoVR钢(简称X610CF钢)力学性能、组织结构及工程应用。该钢具有优异的焊接性能和低温韧性;板厚≤50 mm的钢板焊前不预热或稍加预热而不产生焊接冷裂纹,是制造大型压力容器(特别是低温和常温球罐)、水电站压力钢管的理想用材。This paper introduces the mechanical properties and microstructure of 07MnCrMoVR steel（X610CF）as well as applications situation in engineering project.This steel has excellent weldability and low-temperature toughness,and no crack is formed in t≤50 mm plates after welding even without preheating or with slight preheating before welding.The plates have been applied to manufacture large spherical vessels and pressure pipes for large hydraulic power station.

关 键 词：低焊接裂纹敏感性钢 低温韧性 组织结构 球罐钢
