The reasons for the appearance of cracks in the mounting connection, which is an unequal angle obtained by a plate at a right angle of 8x210x100, are investigated. The limited information received at the standard scope of material tests is shown to assess the processability of the product. Investigation of the composition, structure and viscosity of the material made it possible to establish that in order to obtain a quality product from rolled steel of St3sp, it is necessary to make changes in the technological operations of cutting and bending the production of the part. When performing the cutting operation of sheet metal, the long side of the plate (210 mm) should be placed along the direction of the fibers of the structure. During bending, the edge of the folding of the sheet must be made across the rolled fiber. For steels that are prone to splitting along the fibers of the structure, correct cutting of the sheet will prevent the formation of cracks along the stretched bending surface and fatigue failure during welding and operation of the assembly line.
