Sulphide Stress Cracking of API Carbon Steels

Popis výsledku v původním jazyce

In this paper results of SSC resistance of the same carbon steels are summarized. Several grades of steels have been tested, conforming to API grades X52 and X70 (API 5L Specification). Steels were tested in an as-received state or after laboratory heattreatments including quenching and tempering. Results showed that the resistance of steels to SSC depends strongly on their microstructure. Heats containing bands of non-tempered martensite or bainite exhibited rather poor resistance to SSC and failed atstresses well below the yield strength when tested according to the NACE TM 0177, Method A. It must be pointed out that hardness of all studied steels was well bellow the limit of 22 HRC.Tempering or quenching had a beneficial effect on resistance of steels to SSC despite the fact that mechanical properties (and hardness) increased. All the results indicate that microstructure plays important role also in the case of SSC. If this fact is not respected, a material non resistant to SSC ca
