description: The object of the study was selected sheet steel of the 09Ð¥Ð2ÐÐ grade, the manufacture of which was carried out at the camp 5000 (LPC-3, PAO Severstal). Quenching of sheets after rolling was carried out in a controlled cooling unit (ICC) in the mill stream, tempering â in chamber furnaces (LPTS-3, PAO Severstal), repeated heat treatment (quenching and tempering) â in chamber furnaces in the same LPTS-3. Currently, the most energy-efficient technology for manufacturing rolled steel sheets of the 09Ð¥Ð2ÐÐ grade is the technology of quenching from rolling heating with high tempering. After hot deformation, before accelerated cooling, an inhomogeneous (grain size) austenite structure may form in the sheet roll, which is associated with an inhomogeneous distribution of temperature and deformation effects over the thickness of the sheet. The heterogeneity of the final structure in the thickness of the rolled product increases after the phase transformation during cooling from rolling heating. The standard size of tensile samples is standardized in technical specifications, however, in order to reduce costs, manufacturers make proposals to change the standard size of samples. In this case, the test result of the samples may be affected by both the influence of the scale factor and the location of the sample axis in different structural areas.
