摘要：
The influence of alloying design, controlled rolling technology and cooling system of X100 hot-rolled strips on microstructure and micro-hardness has been discussed in detail in this paper. The results show that optimal chemical composition range of X100 hot-rolled strips is obtained on the basis of X80 by increasing contents of C, Mn, Ni and Mo of X80. The granular bainite microstructure could be refined and the volume fraction and size of M-A islands could be controlled in a reasonable range by reasonably regulating cooling rate and coiling temperature of X100 pipeline steel, which ensure high strength and toughness of X100 pipeline steel.
