Abstract
Types of stainless steel for pressure vessel almost are all austenitic stainless steel and duplex austenitic/ferritic stainless steel.The percentages of designations of nitrogen-bearing steel grade individ-ually are 63 .4%,76 .4% and 60% among all designations of austenitic and duplex stainless steel types used in ASME-2011a,EN 13445:2009 and GB 150-2011 pressure vessel standards.Nitrogen contents of all duplex stainless steels(research after 1971),all super austenitic stainless steels and all super or hy-per duplex stainless steels in stainless steel standards basically are 0.1%~0.6%(call them middle ni-trogen-bearing stainless steel).10 designations of austenitic stainless steel can used for -273 ℃speci-fied in EN 13445:2009 are all nitrogen-bearing steel grade.Nitrogen solubility and content in stainless steel,types of nitrogen-bearing stainless steel,nitrogen effect for performance and structure of stainless steel and use of nitrogen-bearing stainless steel for pressure vessel are discussed.Middle nitrogen-bear-ing(N=0.1%~0.6%)austenitic stainless steels have becomed the most important high performance Types of stainless steel for pressure vessel almost are all austenitic stainless steel and duplex austenitic/ferritic stainless steel.The percentages of designations of nitrogen-bearing steel grade individ-ually are 63 .4%,76 .4% and 60% among all designations of austenitic and duplex stainless steel types used in ASME-2011a,EN 13445:2009 and GB 150-2011 pressure vessel standards.Nitrogen contents of all duplex stainless steels(research after 1971),all super austenitic stainless steels and all super or hy-per duplex stainless steels in stainless steel standards basically are 0.1%~0.6%(call them middle ni-trogen-bearing stainless steel).10 designations of austenitic stainless steel can used for -273 ℃speci-fied in EN 13445:2009 are all nitrogen-bearing steel grade.Nitrogen solubility and content in stainless steel,types of nitrogen-bearing stainless steel,nitrogen effect for performance and structure of stainless steel and use of nitrogen-bearing stainless steel for pressure vessel are discussed.Middle nitrogen-bear-ing(N=0.1%~0.6%)austenitic stainless steels have becomed the most important high performance stainless steels in foreign pressure vessel standards.12 and 14 designations have individually are used in ASME-2011a and EN 13445:2009.But these steels are not used in China pressure vessel standard. There are 23 and 13 designations in GB/T 20878-2007 and GB/T 4237-2007(or GB/T 3280-2007) only.This paper proposes to do more works used for pressure vessels on this basis.关键词
