| Abstract: | The weldability of high toughness refractory and weather-resistant construction steel WGJ510C2, newly developed at 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 heat affected zone (CGHAZ) have been also investigated. The results show that WGJ510C2 steel has low cold-cracking sensitivity and superior weldability, and can be welded by high heat input welding. |
