Abstract
The high level of production quality of electrometallurgical enterprises made it possible to achieve small values of the coefficients of variation of the controlled parameters and introduce a new value into the nominal range of reinforcement classes. In order to launch the production of a new strength class of A550SK reinforcement, studies were conducted to determine the complex of consumer properties. The positive results of the research allowed us to standardize a new strength class, the use of which will allow us to achieve an economic effect by reducing steel consumption.
