英文摘要	Tempering brittleness is an important reason for microcrack formation and cracking in thick wall tube made by steel 1Cr13 which is applied in reactor driving mechanism. This article analysed the quenching effect caused by hot rolling followed by air cooling, tempering brittleness caused by annealing followed by slow cooling, and influence of rolling on the cracking direction. Improper heat treatment condition derives martensite transformation and tempering brittleness, which make the steel cracking when rapidly cold rolling. Tangential tensile stress caused by squashing the tube during rolling is the reason for the formation of longitudinal crack.
