【Abstract】 This article studies the principle on electric chemical canker, and analyzes the cause of austeniticstainless steel destruction by tests of metallographic. It proves that austenitic stainless steel can’t be used in the caseof NaOH. It offers intact precautionary measure for pressure vessel makers select suitable materials and produce.It ensures safety of the use of pressure vessel.更多还原
