Abstract��A kind of washboard��like crack on steel plate surface is introduced. Examination and analysis of macro, micro characteristic and relevant microstructure of the cracked area are carried out. It shows that this kind of crack has relatied to martensitic transformation during rapid cooling from high��temperature zone of austenite on partial surface of steel plate. The self��tempering structure of martensitic transformed has higher hardness, strength and lower plasticity, it will produce crack transverse during rolling.
