Stress corrosion of stainless steel materials such as stainless steel pipes

Conveying or holding corrosive media stainless steel piping and stainless steel containers, the corrosion phenomenon produced under the action of tensile stress is called stress corrosion. stainless steel pipe and other stainless steel stress corrosion caused by tensile stress has welding residual stress and working stress of two kinds, which is dominated by welding residual stress.

Generate stress corrosion of the medium factor is the common content of CI-ion concentration and oxygen content in solution. Easily caused by austenitic stainless steel tubes and other stainless steel stress corrosion medium, austenitic stainless steel equipment is often caused by cooling water, steam, air in the water caused by stress corrosion fracture. Therefore, in the use of Stainless Steel Pipe and other stainless steel materials for stress corrosion caused by the fracture phenomenon in the design of the time should be given sufficient attention.
