| Popis: | We present the results of investigations aimed at the determination of susceptibility of welded joints in low-alloy 14GB pipe steel to sulfide cracking in the presence of technological defects. We established that these joints exhibit no susceptibility to cracking at stresses below −0.5σ0.2 for the base metal, and thatK Iscc in the NACE solution is equal to 28MPa√m. |
