Heat Treatment On Affection Of Organization And Character Of Austenitic Stainless Steel

As China's oil exploitation and depth of the Middle East increase in the number of imported crude oil, raw materials in the petroleum refining industry increasingly high sulfur content, making oil refinery in the heat exchanger caused by hydrogen sulfide stress corrosion cracking problems have become increasingly prominent. The article cited a heat exchanger bundle of steel to prevent corrosion types and methods, analysed on the steel heat exchanger bundle 0Cr18Ni9 of H2S stress corrosion cracking mechanism and the factors affecting 0Cr18Ni9 of hydrogen sulfide stress corrosion resistance of the performance, this system will heat treatment 0Cr18Ni9 system of austenitic stainless steel and Properties of using optical microscopy and other analytical tools in the study of the morphology of the system with the changes of heat treatment, the test results through the use of austenitic stainless steel 0Cr18Ni9 the strengthening of the mechanism were discussed. After looking forward to the appropriate heat treatment process to improve the steel heat exchanger bundle 0Cr18Ni9 better corrosion resistance. With heat treatment process on the steel heat exchanger bundle 0Cr18Ni9 austenitic stainless steel and properties of the study, including 0Cr18Ni9 austenitic stainless steel handle and a solid solution aging treatment, study different solution temperature, the cold temperature, aging temperature of 0Cr18Ni9 of austenitic stainless steel and the impact of the steel precipitates in the strengthening mechanism, and to determine 0Cr18Ni9 the best austenitic stainless steel heat treatment process. After looking forward to the appropriate heat treatment process to improve the heat exchanger bundle 0Cr18Ni9 steel corrosion resistance.
