| Abstract: | Synopsis This paper introduces the development of a new grade steel of 60?kg with low susceptibility to welding crack in the condition of high heat input welding. Main results of the research are described as follows: Cr and B are not the ideal micro-alloying elements for the steel; In cast the ratio of Ti/N in the steel nearly equals to its stoichiometric ratio of 3.42, a finer grain microstructure features the steel, resulting in higher strength and toughness; Tempered sorbite can be considered the ideal microstructure of the steel. |
