The invention relates to a process of producing stainless steel by electrolysis on various metallic and non-metallic surfaces According to the invention, the process consists in that it uses a galvanizing bath based on cyanide-free nickel and chromium salts, the nickel-chromium compositions ranging from 14 to 80 % Ni or 14 to 80 % Cr, a 1 mm thick layer being obtained for a deposition time of about 4 h, the bath comprising NiSO 4 x 7 H 2 O - 180 g/l, Cr 2 (SO 4) 3 x 10 H 2 O - 50 g/l, MgSO 4 x 7 H 2 O- 20g/l, NaSO 4 x 10 H 2 O - 30g/l, H 3 BO 3 - 25 g/l with a distance between anode-cathode of 150 mm, with a pH= 45 5, 35 5 V voltage and 4 6 A/dm 2 current density; the piece the stainless steel layer is deposited on is subjected to machining, chemical degreasing, washing with water, pickling and drying
