Failure Analysis of Stress Corrosion Crack of 1Cr18Ni9 Stainless Steel Cylinder Body
As a kind of corrosion resistant material,stainless steel is widely used in petroleum,chemical,pharmaceutical.Stress corrosion cracking is a main reason that why the stainless steel became disabled.Therefore,it is very necessary to research and study the stress corrosion cracking of stainless steel.The failure analysis to the sample is conducted aiming at the stress corrosion of the stainless steel piston cylinder in a factory.The analysis includes macro analysis,metallographic observation,scanning electron microscopy analysis and XRD analysis.The results of the study show that it is nonmetallic inclusion on the grain boundary,the chloridion in the industrial circulating water and the rough columnar austenitic grains in the organization of the samples that lead to the stress corrosion cracking of the piston cylinder.
