Vanadium & Titanium’s Effects on High Strength Weathering Steel’s Impact Toughness in CGHAZ

Abstract:

The influence of impact toughness in vanadium-bearing high strength weathering steels CGHAZ was researched by welding thermal simulation in this paper. The melting and precipitation situation of V, Ti and N in the high strength weathering steel was analyzed in the process of welding thermal simulation according to relative papers. According to the research, TiN in the steel plays a decisive role in CGHAZ on its impact toughness, and give a suggestion about the content of Ti in order to promote the tested steels impact toughness in CGHAZ.
