Insimbi engagqwali engu-316 kanye nensimbi engagqwali engu-316L zombili ziyi-austenitic, zinamazinga afanayo e-chromium (16–18%), i-nickel (10–14%), kanye ne-molybdenum ephezulu (2–3%). Umehluko oyinhloko okuqukethwe kwekhabhoni kwe-316L okungaphansi kuka-0.03%, uma kuqhathaniswa no-0.08% ophezulu ku-316. Ikhabhoni ephansi inciphisa kakhulu imvula ye-chromium carbide ngesikhathi sokusebenza kokushisela.
316 vs 316L
*
I-Chromium carbide ifika emingceleni yokusanhlamvu lapho amazinga okushisa aphezulu, ikakhulukazi phakathi kuka-450°C no-850°C, njengasezindaweni ezithinteke ukushisa nge-weld. Lokhu "kuzwela" kunciphisa i-chromium endaweni futhi kubangele ukuthambekela ekugqwaleni kwe-intergranular, ikakhulukazi ezindaweni ezinolaka ze-chloride.
Ukusebenza, Ukumelana Nokugqwala, kanye Nokushibilika
Izici Zokumelana Nokugqwala
Insimbi engagqwali engu-316 kanye nensimbi engagqwali engu-316L zibonisa ukumelana okuphezulu nokugqwala komoya kanye namakhemikhali ngenxa yokuqukethwe kwayo okungu-2–3% we-molybdenum. Umehluko phakathi kwensimbi engagqwali engu-316 kanye ne-316L usekusebenzeni kwayo ngemuva kokwenziwa: okuqukethwe kwekhabhoni engu-316L kungu-≤0.03%, uma kuqhathaniswa no-≤0.08% ku-316, okunciphisa kakhulu imvula ye-carbide emingceleni yokusanhlamvu ngemva kokushisela. Lesi sici senza insimbi engagqwali engu-316L ibe ngcono kakhulu ezindaweni ezichayeke njalo kuma-chloride nama-acid, njengehadiwe yasolwandle, amapayipi enqubo, kanye namathangi amakhemikhali, ukugcina ukumelana nokugqwala kwemigodi kanye nemifantu, ngisho nasezindaweni zokushisela.
Izinto Okucatshangelwayo Ngokushibilika
Insimbi engagqwali engu-316L inikeza ukushibilika okuphezulu kwezakhiwo ezishibilikile ezimbonini zokwakha, zezokwelapha nezamakhemikhali. Okuqukethwe kwayo okuphansi kwekhabhoni (u003c0.03%) kuvimbela ukwakheka kwe-chromium carbide ngesikhathi sokuvezwa ukushisa, kuvimbela ukugqwala kwe-intergranular kanye nokulahlekelwa ukumelana nokugqwala emajoyintini. Lesi sici sigwema ukushibilika okubuthakathaka, ukukhiqizwa kokugqwala, kanye nokugcinwa okubizayo, okuyizingozi lapho insimbi engagqwali engu-316 isetshenziswa ngendlela engafanele ezisetshenzisweni ezinobuningi obukhulu bokushibilika noma ukujikeleza okuphindaphindiwe kokushisa. Isibonelo, amadivayisi okufakelwa kwezokwelapha, imithambo yokucindezela, kanye nemishini yokucubungula ukudla kusebenzisa kuphela i-316L ukugwema ukwehluleka kwendawo yokushibilika.
Izinselele Zokuhlukanisa I-316 vs 316L
Imikhawulo Yokuhlola Okubonakalayo
Insimbi engagqwali engu-316 kanye nensimbi engagqwali engu-316L azibonakali kahle. Umbala ofanayo, ukukhazimula, kanye nokuphela kobuso kwenza ukuhlolwa kokukhanya kungasebenzi ekuqinisekisweni kwebanga. Abakhiqizi, abenzi bezinto, kanye nabaphakeli basengozini yokulebula kabi ngesikhathi sokuthengwa, ukugcinwa, kanye nokuhlanganiswa. Ukukhetha okungalungile kuphazamisa ikhwalithi yokushisela, kunciphisa izinzuzo zensimbi engagqwali engu-316L kunensimbi engagqwali engu-316. Ukufaniswa okungalungile kwandisa imisebenzi yokulungisa futhi kungase kwephule ukuhambisana nezindinganiso emikhakheni yezokwelapha, yokudla, kanye namadivayisi ezokwelapha, lapho ikhabhoni ephansi iphoqelekile.
Izingozi Zokuhlonza Okungalungile
Izakhiwo ezihlanganisiwe ezisebenzisa i-316 esikhundleni se-316L zibiza ukugqwala kwe-intergranular endaweni ethintekile ukushisa, kunciphisa impilo yesevisi. Izindawo ezicebile nge-chloride zisheshisa lokhu konakala—izibonelo zifaka phakathi amapayipi olwandle, amathangi amakhemikhali, kanye nemishini yokusebenza esebenza ngaphezu kuka-450°C. Ukuxubana okukodwa kungaqala isikhathi sokungasebenzi esibi kakhulu esingahleliwe. Amaphutha aphindaphindwayo abeka engcupheni izinhlawulo zezimali, izimangalo zewaranti, kanye nokulahlekelwa ukulandeleka. Ukuhlolwa kwemithetho kuvame ukudinga ubufakazi bebanga, okugqamisa ukubaluleka kokuqinisekiswa kwezinto okunembile. Ukuhlaziywa kwe-ED XRF nge-spectrometer ye-XRF ehlakazekayo yamandla, ikakhulukazi amadivayisi e-ED XRF aphathekayo njenge-Lonnmeter, kuhlinzeka ngokwahlukana kwezinto ezibalulekile ekuphathweni kwezinto okunembile kanye nensimbi engagqwali engu-316 vs 316L yezinhlelo zokusebenza zokushisela.
I-ED-XRF --Ithuluzi Elithembekile Lokuhlonza Insimbi Engagqwali
Izimiso ze-ED-XRF Spectrometry
I-Energy Dispersive X-Ray Fluorescence (ED-XRF) ilinganisa ukwakheka kwezinto eziyisisekelo ngokulinganisa ukukhishwa kwe-X-ray okuphawulekayo okuvela kumasampula ensimbi engagqwali. I-spectrometer iyazigqaja ekuhlukaniseni insimbi engagqwali engu-316 nensimbi engagqwali engu-316L ngokulinganisa ngokunembile amazinga ezinto ezixubayo, kufaka phakathi umkhawulo wekhabhoni oyinhloko ochaza umehluko phakathi kwamazinga ensimbi engagqwali angu-316 no-316L. I-ED-XRF ayidingi amazinga okulinganisa, ibala ngokuqondile amazinga ngokusebenzisa indlela ye-Fundamental Parameter (FP) yazo zonke izinto eziyinhloko njenge-Cr, Ni, Mo, ne-Fe. Ngomshini wokuthola i-silicon drift, i-ED-XRF inikeza ukuhlaziywa okungonakalisi, kwesikhathi sangempela okufanelekela izindawo zokukhiqiza kanye namalebhu okulawula ikhwalithi. Ukulungiswa kwe-matrix kanye nama-algorithms esofthiwe kuqinisekisa ukuthi imiphumela ifinyelela ukunemba kwebanga lelebhu ngaphandle kokudinga ukuncibilika kwesampula noma ukwelashwa kwendawo.
Izinzuzo Ngaphezu Kokuhlolwa Okuvamile
I-ED-XRF yenza kube lula ukuqinisekiswa kwebanga uma kuqhathaniswa nokusika kwamakhemikhali noma ukuhlaziywa okubhubhisayo. Abasebenzi bahlukanisa ngokushesha phakathi kwensimbi engagqwali engu-316 nengu-316L yokushisela, ukufakwa kwempahla, kanye nezicelo zokuhambisana nomthetho. Ukuskena okukodwa kunikeza amaphrofayili agcwele e-alloy, okusekela ukuqinisekiswa kwekhwalithi okusheshayo futhi kunciphisa ingozi yokuhlanganiswa kwebanga. Le ndlela yandisa umkhiqizo, inciphisa izindleko zokuhlola eziphelele, futhi iqeda ukubambezeleka okukhona emisebenzini yelabhorethri engaphandle kwendawo.
Ukusebenzisa i-Lonnmeter XRF Alloy Analyzer ukuze kuqinisekiswe i-316/316L
Izici Eziyinhloko kanye namapharamitha Okusebenza
I-Lonnmeter XRF Alloy Analyzer yenza ukuskena kwezinto ezisezingeni eliphezulu okuqondiswe ezintweni ezixubile ensimbini engagqwali eqinile. I-spectrometry yayo ilinganisa ngokunembile okuqukethwe kwekhabhoni ephansi okubalulekile ekuhlukaniseni insimbi engagqwali engu-316 uma kuqhathaniswa nensimbi engagqwali engu-316L, ehluke kakhulu ngengxenye yekhabhoni engaphansi kuka-0.03% ku-316L. Ukumelana okunamandla komswakama nothuli, izindlu eziqinile, kanye nokuvikelwa kokushaqeka kuvumela ukusetshenziswa okuthembekile ezitshalweni zensimbi, ezitolo zokukhiqiza, nasezindaweni zokwakha. Ukusebenza kulula, kudinga ukuqeqeshwa okuncane. I-interface isekela ukubika kwedijithali nge-CSV kanye ne-PDF ukuthumela ngaphandle ukuze kutholakale amarekhodi okuhambisana nomthetho. Iphathwa ngesandla, inikwe amandla yibhethri, futhi ingaphansi kwamakhilogremu amabili, i-Lonnmeter ivumela ukuhlaziywa kwe-ED XRF endaweni kanye nokulandeleka ekuphathweni kwempahla.
Kungani Ucela Isilinganiso
I-Lonnmeter XRF Analyzer yehlisa amaphutha omqhubi kanye nokulungiswa kabusha okubizayo ngokuzenzakalelayo ukunqunywa kwebanga. Amaqembu esevisi athuthukisa ukuhamba komsebenzi kanye nokuqinisekiswa kwekhwalithi ngemiphumela yedijithali, okunciphisa isikhathi sokungasebenzi. Ukucela isilinganiso kuxhuma amaqembu ekulungiselelweni kwedivayisi okwenziwe ngokwezifiso, ukwesekwa kobuchwepheshe, kanye nokuqeqeshwa kokufakwa okungenamthungo kuzo zonke izinhlelo zokusebenza zokuhlonza i-alloy ezibalulekile.
Imibuzo Evame Ukubuzwa
Uyini umehluko omkhulu phakathi kwensimbi engagqwali engu-316 kanye ne-316L?
Insimbi engagqwali engu-316L inciphisa okuqukethwe kwekhabhoni kube ngaphansi kuka-0.03%, uma kuqhathaniswa no-0.08% ensimbi engagqwali engu-316.
Kungani i-316L ifaneleka kakhulu ezakhiweni ezihlanganisiwe?
I-316L's low carbon ivimba ukwakheka kwe-chromium carbide ezindaweni zokushisela kanye nezindawo ezithintekile ukushisa. Lokhu kuvimbela ukuzwela, kugcina ukumelana nokugqwala ngemva kokushisela noma isevisi yokushisa okuphezulu.
