Abstract: The aim of the present paper deals with the production of heavy steel forgings of micro-alloyed steels. Improvements of mechanical properties of forgings up to level by sheets, strips and tubes have been achieved by mean of application of micro-alloying elements and thermo-mechanical treatments. The effect of vanadium addition has been assessed by means of metallurgical modelling step followed by a laboratory demonstration phase by means of ingot manufacturing. Heat treatment has been designed aimed to achieve the desired target tensile properties. Results show that ASTM A694 F70 grade requirements can be fulfilled by 0.15% V addition and a proper heat treatment in a ferrite-pearlite microstructure, representative of a forged component.
