The paper gives the results of tests carried out into the stress corrosion cracking in duplex stainless steel (Type 02Cr22Ni5Mo3N, W.Nr. 1.4462); this grade is characterized by high resistance to intergranular corrosion, while resistance to stress corrosion cracking may be impaired by temperature and mode of loading. This behaviour requires special attention. The tests included testing in 35% MgCl 2 solution under constant load at 120°C, the drop evaporation test using a 0.1 mol · 1 − NaCl solution and the slow strain rate test in 35% MgCl 2 solution at 120°C.
