摘　　要：本文着重介绍武汉钢铁公司近年来研制开发的第二代高强度低合金钢—高强韧性WDL系列钢的综合性能及应用情况。该钢具有优异的焊接性能和低温韧性,板厚≤50mm钢板焊前不预热或稍加预热而不产生焊接裂纹,是制造大型压力容器（特别是低温和常温球罐）、水电站压力钢管和水轮机蜗壳、高寒地区使用的大型工程机械、大跨度桥梁及海上采油平台等装备的理想用材。This paper introduces the comprehensive properties and applications of new times HSLA steel- 07MnCrMoV series steel (WDL) with low susceptibility to weld crack researched and developed by the Wuhan Iron and Steel Company in recent years. This steel was verified as being excellent in weldability and low-temperature toughness,and producing no cracks in t≤50 mm plates without preheating or with slight preheating before welding.The plates have been applied to the manufacture of large spherical vessels,high water fall-difference power station pressure pipes thigh stress and load engineering machinery.
