| Abstract: | Austenitic stainless steel has good toughness but low yield strength.The yield strength of austenitic stainless steel could be significantly increased by stain strengthening technology,thus improving the carrying capacity and thinning the wall thickness of austenitic stainless steel pressure vessels to save material.The basic principle and process of the stain strengthening technology was introduced,then the properties of strengthened austenitic stainless steel were dissertated,including strength,corrosion resistance,stress corrosion cracking and hydrogen embrittlement.Finally,further research recommendations were proposed in order to realize the concept of green manufacturing on light-duty of pressure vessels,which has equal emphasis on safety and economy. |
| Keywords: | austenitic stainless steel stain strengthening light-duty design pressure vessels stress corrosion cracking hydrogen embrittlement |
