This note describes a short study of two commercial eutectoid steels of UTS 1700 MPa. A previous study had shown them to have identical SCC behaviour when precracked. Here the specimens were smooth and tested In a standard FIP procedure using NH4CNS. The wide difference in times to rupture has been shown to be due to the level of residual surface, stress.
