| Abstract: | Based on an investigation on elements reponsible for the cracks of 18Cr一2Mo ferrite stainless steel shell and cold-rolled pipe,a conclusion is made that it is the double weakening effects by comparatively high contents of C,N,S interstitial atoms and their flake deposition on the{100}face that caused the cracks,Therefore,to reduce the amount of the said atoms will be effective on curbing development of the said cracks. |
