Ukuqhathaniswa kokusebenza kwe-304L ne-316L ye-Brushed Stainless Steel Plate

304 kanye no-316 womabili amakhodi ensimbi engagqwali.Empeleni, awehlukile.Zombili ziyinsimbi engagqwali, kodwa zingezezinhlobo ezahlukene uma zihlukaniswa.Izinga lensimbi engagqwali engu-316 liphakeme kunalelo lensimbi engagqwali engu-304.Ngokusekelwe ku-304,316 insimbi engagqwaliihlanganisa i-metal molybdenum, engahlanganisa ngokuqhubekayo ukwakheka kwamangqamuzana ensimbi engagqwali.Yenze ingagugi futhi i-anti-oxidation, futhi ngasikhathi sinye, ukumelana nokugqwala kukhuphuka kakhulu.
Ukuqhathaniswa kokusebenza kwe-304L kanyeI-316L ye-Brushed Steel Plate
Ukumelana nokugqwala kwensimbi engagqwali kubaluleke kakhulu kunokumelana kwayo namabala.Njenge-alloy, ukwakheka kokuqala kwensimbi engagqwali kuyinsimbi, kodwa ngenxa yokwengezwa kwezinye izakhi, kungafinyelela izici eziningi ezifiselekayo zohlelo lokusebenza.I-Chromium iyisici esinqumayo kunsimbi engagqwali, okungenani u-10.5% wokwakheka.Ezinye izakhi ze-alloying zihlanganisa i-nickel, i-titanium, ithusi, i-nitrogen ne-selenium.
Umehluko phakathi kwe-304L ne-316L ye-Brushed Stainless Steel Plate ubukhona be-chromium, insimbi engagqwali engu-316L inokumelana nokugqwala okungcono, ikakhulukazi endaweni ephakathi enosawoti omningi.Ngezinhlelo zokusebenza ezinemikhiqizo yensimbi engagqwali yangaphandle, insimbi engagqwali iyinto efanelekile ukumelana nokugqwala kokuchayeka ngaphandle isikhathi eside.
ukumelana nokugqwala kwemvelo
Okuqukethwe okuhlukile kwe-chromium nezinye izakhi kungabonisa amazinga ahlukene okumelana nokugqwala.Amabanga amabili ajwayelekile ensimbi engagqwali angu-304 kanye nama-316. Ukugqwala kuyinto yemvelo, njengoba nje insimbi iphendula ngokwemvelo nendawo eyizungezile.Eqinisweni, izakhi ezimbalwa kakhulu ezingenzeka ngendlela ehlanzekile - igolide, isiliva, ithusi, neplatinamu yizibonelo ezimbalwa kakhulu.
I-Chromium oxide yakha ifilimu yokuvikela eyakheke ngaphakathi
Ukugqwala kuyinqubo lapho ama-athomu ensimbi ehlangana khona nomoya-mpilo kuma-molecule wamanzi, futhi umphumela uba ibala elibomvu elivame ukuba libi kakhulu—okugqwala okwengeziwe.Kulokhu, insimbi ne-carbon steel isengozini kakhulu kulokhu kugqwala.
Insimbi engagqwali inekhono lemvelo lokugqwala phezulu, kwenzeka kanjani lokhu?I-Chromium kuzo zonke izinsimbi ezingenasici isabela ngokushesha kumoya-mpilo, njengensimbi.Umehluko wukuthi kuphela ungqimba oluncane lwe-chromium oluzokwenziwa i-oxidized (imvamisa nje i-molecule encane ebugqileni).Ngokumangalisayo, lolu ngqimba oluncane lwesivikelo luhlala isikhathi eside.
I-304L yensimbi engagqwali ebhulashiwe inokubukeka okuhle nezindleko zokuyilungisa eziphansi.Insimbi engagqwali engu-304L ayijwayele ukugqwala, ngakho-ke ivamise ukusetshenziswa ezitsheni zokupheka nasezintweni zokudla.Kodwa iyakwazi ukungenwa ama-chloride (imvamisa ezindaweni ezinosawoti omningi).I-Chloride idala uhlobo lwendawo yokugqwala ebizwa ngokuthi “indawo yokugqwala” edlulela esakhiweni sangaphakathi.
I-304 insimbi engagqwali iyinsimbi engagqwali esetshenziswa kakhulu emhlabeni.Iqukethe u-16% -24% we-chromium futhi kufika ku-35% nickel - namazinga aphansi ekhabhoni ne-manganese.Uhlobo oluvame kakhulu lwensimbi engagqwali engu-304 yi-18-8, noma i-18/8 yensimbi engagqwali, ebhekisela ku-18% we-chromium no-8% we-nickel.
I-316 insimbi engagqwali futhi iyinsimbi engagqwali esetshenziswa kakhulu.Izakhiwo zayo ezingokomzimba nezemishini zifana nensimbi engagqwali engu-304.Umehluko wukuthi i-316 insimbi engagqwali iqukethe 2-3% molybdenum, okwandisa amandla nokumelana nokugqwala.Ngokuvamile uchungechunge lwama-stainless steels angu-300 lungaqukatha kufika ku-7% i-aluminium.
304L kanye 316Lizinsimbi ezingenasici ezibhulashiwe(njengezinye izinsimbi ezingenasici ezingama-300) zisebenzisa i-nickel ukuze zigcine izinga lokushisa eliphansi lobuhle bazo.
