654SMO Super Austenitic Stainless hlau (UNS S32654)
654SMO yog super austenitic stainless hlau nrog 25 feem pua chromium, 23 feem pua nickel, thiab 7 feem pua molybdenum uas muaj corrosion kuj piv rau qhov zoo tshaj plaws nickel-based alloys thiab tuaj yeem hloov cov hlau-nickel-based lossis txawm tias nickel-based corrosion-resistant alloys hauv ntau qhov kev tshaj tawm, yog li sau qhov sib txawv ntawm cov hlau tsis muaj steel thiab high-nickel corrosion-resistant alloys tsis muaj siab tsis kam rau pitting thiab crevice corrosion. Cov ntsiab lus nitrogen ntawm 654SMO super austenitic stainless hlau yog ob zaug ntawm 254SMO alloy, uas muaj lub zog tensile zoo dua li 904L thiab 254SMO.
Nyob rau hauv cov khoom tov, 654SMO alloy muaj superior plasticity, toughness, thiab lub zog zoo rau cov pa austenitic thiab 6 feem pua Mo austenitic stainless hlau; nws cov khoom siv kho tshuab txawm tias sib npaug rau qee cov nickel-based corrosion-resistant alloys. Nyob rau hauv dej hiav txwv, thiab inflatables, nrog rau lub xub ntiag ntawm qhov khoob, tsis tshua muaj scouring tej yam kev mob, muaj zog tsis kam mus rau pitting corrosion, thiab zoo kev nyuaj siab corrosion kuj, 654SMO super austenitic stainless hlau muaj zoo heev nyob rau hauv lub zos corrosion kuj. Kev ntxhov siab corrosion kuj yog cov khoom siv hloov pauv rau cov nickel-based alloys thiab titanium alloys. Qhov thib ob, nws muaj peev xwm tiv taus qhov kub thiab txias dua li 904L thiab 254SMO.
654 SMO muaj superior corrosion kuj nyob rau hauv khib nyiab incineration cog roj txias xov xwm tsis tsuas yog rau super austenitic stainless hlau 254 SMO thiab super duplex stainless hlau uas muaj 6 feem pua Mo, tab sis kuj mus rau lub siab chromium thiab molybdenum nickel-raws li corrosion resistant alloys Inconel 625, Hastelloy C276. , Hastelloy C22, thiab titanium Gr2.
