Influence of the Proceses Parameters on Mechanical Properties of Nb Microalloyed Tubes

In the paper are presented resu1ts of investigations on hot-rolling welding tubes micoalloyed with Nb and no microalloyed steel. The experimental work of investigations included create chemical composition, selection of rolling parameters to a final dimension of production on a stretc - reducing milI and testing mechanical properties of tubes. Special attention was given to the degradation of structure and its influence on the mechanical properties tubes.
