An investigation was undertaken to develop a new economical molybdenum HSLA steel for X-70 linepipe. The steel composition and processing variables studied were for production on a plate mill. It was found that a steel containing 0.07-0.09% C, 1.40-1.60% Mn, 0.20-0.35% Si, 0.13-0.17% Mo, and 0.03-0.05% Nb can be utilized for X-70 pipe. The required strength and toughness are achieved by controlled rolling with finishing temperatures in the intercritical range.
