Abstract: This work presents the influence of the surface treatment and plastic strain of Cr-Ni-Mo stainless steel, intended for implants applied in urogenital surgery, on the steel's corrosion resistance. Tests were carried out in simulated urine at a temperature of 37 ± 1°C and pH = 6–6,4. In particular, pitting and crevice corrosion resistance tests were carried out. Furthermore, through the applied technique of stent implantation, the deformability of the passive layer was evaluated. The deformability tests of the passive layer were carried out with the use of a bend test followed by a corrosion test.
