The results show that it is possible to improve the properties of low carbonsteel against straining and aging by controlling the hot working conditions andthat the grain size and microstructure of killed steel may vary within fairly widelimits and yet its impact values after strain-aging may still remain within the re-quired standard; whereas strict control of the grain size and microstructure is ne-cessary in order to produce rimming steel of required impact value after strain-aging.
