摘要
Abstract
Low alloy steel/stainless steel bimetal composite structural components have excellent corrosion resistance and low production cost,and are used in the field of CO2 and H2S oil field surface gathering pipeline and other fields.However,due to the differences in thermal properties between the low alloy steel and stainless steel,there will be large residual stress near the bimetal interface in the process of metallurgical bonding.Under the dual action of residual stress and corrosive medium,stress corrosion cracking(SCC)is easy to occur near the interface of bimetal composite structural components.The manufacturing technology of the low alloy steel/stainless steel bimetal composite structural components are briefly introduced,the research status and the key technologies of diffusion of the alloy elements and the stress corrosion cracking on the stainless steel side near the bimetal connection interface are summarized,the selection principles of transition materials for the low alloy steel/stainless steel bimetal structural components are analyzed,and the suggestions for the selection of the transition materials or the welding materials are proposed,the reference for the research and application of bimetal composite structural components are provided.关键词
