The production of API line pipe with subarctic, low-temperature toughness from Steckel mill coiled plate is a challenge for the steel producer. An appreciation of the characteristics of Steckel mill rolling, in conjunction with the key through-process microstructure and operational parameters, is required. This includes alloy design and the development of an appropriate time-temperature strain path. This paper reviews these metallurgical and process factors in combination with targeted equipment upgrades undertaken by Primetals Technologies Ltd. on a recent Steckel mill project. The practical considerations in realizing these aims are also reported.
