COMPARISON OF RESISTANCE OF QUENCHED AND TEMPERED STEELS TO SULPHIDE STRESS CRACKING

Popis výsledku v původním jazyce

Presented paper compares resistance of selected types of quenched and tempered steels to sulphide stress cracking (SSC). Experiments were made with use of microalloyed steel grades X52 and X60 according to API and supermartensitic steel 13Cr6Ni2.5Mo. Heat treatment was realised in laboratory conditions. The samples were subjected to tensile tests, during which the samples were exposed to stress corresponding to a certain degree of yield strength ant time to rupture of individual samples of steels was measured. Detailed description of the testing method is given in NACE TM 0177. Fractures areas of the samples were then investigated in detail with use of scanning electron microscopy, namely of the scanning electron microscope JEOL JSM 50-A. Mutual comparison of resistance of steels to sulphide stress cracking showed that the worst was supermartensitic steel 13Cr6Ni2.5Mo, in spite of the fact that it has great structural advantage, since it contains high portion of reverse austenite (appr
