Q460CFD steel plate datasheet

1. Q460CFD is a high-strength steel plate with low welding crack sensitivity. The specified thickness is between 5mm-100mm and the implementation standard: YB/T4137-2013. The name of Q460CFD steel plate consists of the first letter Q in Chinese pinyin representing the yield strength "yield", the prescribed yield strength value, the English letter (CF) that represents low welding crack sensitivity internationally, and the quality level (C, D, E). partial composition.
