Abstract
The manufacture of 12Kh18N10T austenitic stainless steel bolts with a hexahedral head is analyzed. The mechanical properties of 12Kh18N10T steel are tested after tempering and calibration to the initial dimensions. Two production technologies are considered: cold stamping with trimming of the hexahedral head; and cold flash-free stamping of a hexahedron. The quality of the head is better in the latter case. The best depth of the depression in the hexagonal bolt head made by flash-free stamping is determined.
