Popis: The influence of strip winding on the structure formation and microalloying of X70 steel with added Ni, Cu, and Mo is investigated. Decrease in winding temperature increases the content of transformation products of nonpolygonal morphology. The temperature conditions in which nanoparticles (3–8 nm) of Nb and V carbonitrides are formed in the steel after winding are established. At OAO Severstal, tests have been conducted on the production of X70 steel strip (thickness 14–16 mm) with uniform mechanical properties. It is found that sheet of measured length may be supplied.
