主　　题：Austenitic stainless steel Copper Edge crack Microstructure Ferrite 

摘      要：Cu is known to affect the edge cracking characteristics of austenitic stainless steel as it causes *** hot rolling test of four kinds of austenitic stainless steel with different copper content(0,2.42,3.60 and 4.35 wt.%)was carried out to examine the effect of hot rolling cracks on steel containing different copper *** evolution of crack and microstructure was analyzed using the scanning electron microscope,energy-dispersive spectrometer,electron back scattered diffraction and transmission electron *** results showed an upward trend in edge cracking degree when Cu content was 4.35%,and the crack extended from the edge of the steel plate to the middle by about 14 ***,severe oxidation was observed inside the crack by *** the increase in copper content at 1250℃,the content of{110}brass and{112}copper textures *** the content of copper was 4.35%,the decrease was most significant,and{112}copper texture content decreased to only 0.5%.Generally,the textures of 2.42%Cu and 3.60%Cu 304L steel changed little,while a large change in the texture of 4.35%Cu 304L steel was *** conclude,the increase in rolling temperature can prevent edge crack and its propagation effectively.
