Abstract : To obtain definite information concerning the relationships among chemical composition, underbead weld cracking, and the mechanical properties, especially the tensile and notched-bar impact characteristics, a series of 30 laboratory heats was made and studied in the hot-rolled state to determine the individual influence of each of the following constituents when varied over a range sufficiently broad to definitely establish the trend of the effect; carbon, manganese, silicon, molybdenum, vanadium, and aluminum. For a standard chemical composition, a typical HTS analysis was selected, and the elements studied were then varied one at a time in this standard composition.
