Experimental Research for Cold Spinning Processing Properties of S30403 + Q345R Rolled Clad Plate

The cold spinning(two·steps practice)for pressure vessel head had been widely used in pressure vessel manufacturing．Cold hardening，cracking or stripping and etc．in cold spinning of clad plate head shall be considered in spinning process．The cold spinning processing for explosion cladding plate is now a mature technique after accumulating of experience，and improving of equipment and technique for many years．The cold spinning experiment in this article is with vacuum rolled clad plate manufactured， base metal Q345 R and clad metal$30403，to research the clad plate cold forming process and its effect on base metal mechanical properties and processing properties，and clad metal corrosion resistance properties，to test the effect of heat treatment on corrosion resistance properties of clad metal．
