ent that boron does not impart ductility to steel. The reduc-tion in area figures for the 1340 and 1038 with boron are virtually identical. However, the ductility of the low car-bon-boron steel is consistently higher and this is attributable to the lower carbon content of that steel. Boron treated steels with carbon contents of 0.35- 0.40%Web
