RECENT DEVELOPMENTS OF ADVANCED AUSTENITIC AND DUPLEX STAINLESS STEELS FOR OIL AND GAS INDUSTRY
The demands for fuel and the development of the fuel exploitation processes have made it economically possible to produce oil-gas from deeper and more corrosive wells where the parameters such as high chloride,H2S or CO2 content,high temperature and pressure,erosion and bioactivities in seawater should be considered.In these applications,special grades of stainless steels with greater corrosion resistance at a broad range of temperatures and high strength have to be used to meet the requirements.This paper provides an overview on the development,properties and applications of these advanced materials for oil & gas industry.They include recently developed advanced super austenitic stainless steels with high Mo,Ni,Cr and N contents with a PRE(pitting resistance equivalent)number up to 52 and hyper duplex stainless steels.
