Effect of TMCP rolling schedules on the microstructure and performance of X70 steel

Four laboratory rolling schedules were devised and produced from a thick-wall API X70 steel plate. The microstructure and crystallographic texture were characterized followed by an evaluation of the performance of the rolled steels by investigating the mechanical properties and SCC susceptibility. High pH Stress Corrosion Cracking (SCC) is a damaging form of environmental corrosion that can cause rapid failure of buried gas transmission...
