Experimental Investigation on Cold Crack Sensibility of 321-Q370q Clad Plates

Q370q steel is a new type bridge steel which is codeveloped by WUHAN IRON AND STEEL GROUP CORP and CHINA ZHONGTIE MAJOR BRIDGE ENGINEERING GROUP CORP.In order to realize corrosion prevention once for all,321-q370q clad plates was fabricated by means of explosive welding.Reseach on 321-q370q clad plates welding cold cracking sensitivity was carried out,and the results show that 321-q370q plates have excellent anti-cracking performance.
