摘要
对武钢研制的高性能耐火耐候建筑用钢WGJ510C2的焊接性能,包括最高硬度、斜Y坡口、手弧焊焊 接接头力学性能和不同线能量下模拟焊接热影响区(CGHAZ)的组织结构及该钢的实际应用进行了研究。试验 结果表明:该钢具有低的冷裂纹敏感性,其焊接性能优良,并能承受大线能量焊接。
The weldability of high-toughness refractory and weather-resistance construction steel WGJ510C2 newly developed in Wuhan Steel, has been evaluated by using the maximum hardness and Y-groove test methods. The microstructure and mechanical properties of the steel, its weldment and simulated coarse grain affected zone (CGHAZ) have been also investigated. The results show that WGJ510C2 steel has low cold-cracking sensitivity and superior weldability. And a high heat input weldability is also integrated in this steel.
