The analysis of data on stress corrosion cracking of different classes steels in sour H2S-CO2-Cl- solutions is carried out. The dependence of the time to failure and speed of stationary corrosion on the outside (the concentration of the solution components, temperature, the value of the tensile stress) and internal (the degree of alloying of Cr, Ni, Mo, the yield strength of steel) of the corrosion parameters is obtained The resulting expression will allow to evaluate the corrosion behavior and the possibility of using steel in an aggressive environment without long and expensive field tests.
