Conclusion
An increase in sheet thickness during the normalization of steel 06G2AF from 12 to 80 mm gives rise to an approximate 15% reduction in the strength level (σ0.2, σu); this is caused primarily by a change in the conditions of formation, the dimensions, and character of distribution of disperse vanadium carbonitrides in the ferritic matrix, and also by enlargement of the ferrite grain; the plasticity and semibrittleness temperature do not change in this case.
