High strength line pipe steels needs to have good crack arrestability to arrest cracks in the pipe body even if brittle fracture occurs at welds, or running ductile fractures occur in the pipe body. The drop weight tear test (DWTT) is one of the major test methods to evaluate crack arrestability of brittle and running ductile …
