| Abstract: | The yield strength of austenitic stainless steel could be effectively increased by strain strengthening technology. Consequently, it can reduce the pressure vessel＇ s wall thickness and weight, save the vessel＇ s manufacture and transportation energy consumption, achieve light-weight of austenitic stainless steel pressure vessel. The basic principle and process of the stain strengthening design technology for austenitic stainless steel pressure vessels is introduced, then the properties of strengthened austenitic stainless steel were dissertated, including yield strength, creep, fatigue, uniform corrosion, stress corrosion cracking（SCC）. Then, further research direction was proposed in order to achieve light-weight of austenitic stainless steel pressure vessel. |
