Abstract
The resistance of some low-alloy tubular steels to sulphide stress cor rosion cracking (SSCC) was assessed. The influence of microstructure a nd non-metallic inclusions on SSCC susceptibility was investigated. Th ree groups of differently heat-treated low-alloy steels with various m icrostructure and shape of non-metallic inclusions were used. Threshol d values sigma(th) and K(ISSC) were determined. To analyse specific mi crostructural mechanisms of damage accumulation in SSCC processes the fractographic and metallographic methods were used.
