Hastelloy C-276 sastāvdaļa analīze
C-276 Hastelloy is a nickel-molybdenum-chromium-iron-tungsten nickel-based alloy and is the most corrosion-resistant among modern metal materials. Mainly resistant to wet chlorine, various oxidizing chlorides, chloride salt solutions, sulfuric acid and oxidizing salts, and has good corrosion resistance in low and medium temperature hydrochloric acid. Therefore, in the past thirty years, it has been widely used in harsh corrosive environments, such as chemical industry, petrochemical industry, flue gas desulfurization, pulp and paper making, environmental protection and other industrial fields.The various corrosion data of Hastelloy C-276 alloy are typical, but they cannot be used as specifications, especially in unknown environments, and materials must be selected after testing. There is not enough Cr in Hastelloy C-276 alloy to resist corrosion in strong oxidizing environments, such as hot concentrated nitric acid. The production of this alloy is mainly for chemical process environments, especially in the presence of mixed acids, such as the discharge pipe of flue gas desulfurization systems.
Hastelloy C-276 performance
The alloy ir teicami korozija izturība pret lielākā daļa kodīgs vidēji in abi oksidēti un samazināti stāvokļi. Teicami izturība pret piķis korozija, plaisa korozija un stress korozija plaisāšana. Sakausējumi ir piemēroti lietošanai in a šķirne of ķīmiskie procesi industrija satur oksidējošie un samazinošie barotnes. The korozijas-izturīgi C276 augstas temperatūras sakausējums loksnes ir augsts molibdēns un hroms saturs, kas padara the sakausējums izturīgs to hlorīds jons erozija. The volframs elements arī tālāk uzlabo tā korozija izturība.
