316/316L vs 304/304L

Uhlobo 316/ 316L/316H insimbi engagqwali ye-austenitic ehloselwe ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu, ukuqina nokusebenza, kanye nokumelana nokugqwala okuthuthukisiwe.Uma kuqhathaniswa nensimbi engagqwali engu-304, i-316 iqukethe amaphesenti aphezulu e-molybdenum (Mo 2% -3%) kanye ne-nickel (Ni 10% kuya ku-14%), i-Molybdenum inokumelana nokugqwala okungcono, ikakhulukazi kokugqwala kwe-pitting kanye nokuqhekeka ezindaweni ze-chloride.I-316 inokuqina okuhle kakhulu kanye nezakhiwo zemishini emazingeni okushisa angaphansi kukaziro, ilungele ukugoqeka okubandayo, ipuleti lokugaya eliqhubekayo kanye nefomu lepuleti lepuleti, ububanzi bufika kumayintshi angu-60.

316L/TP316L Ipayipi Lensimbi Engagqwali

I-Grade 316L ibhekisela ku-S31603 UNS desination 1.4404, inokumelana nokugqwala okungcono kune-TP316 ngenxa yokuqukethwe kwe-Carbon ephansi.316L okuqukethwe kwekhabhoni ephezulu 0.03% okuthi 316 ubuningi obungu-0.08%, ikhabhoni ephezulu izokhuphula ukugqwala kwe-intergranular.Ngakho-ke, i-316L ilungele izinhlelo zokusebenza lapho imvula yekhabhoni idinga ukugwenywa.Le nsimbi engagqwali isetshenziswa kabanzi ukushisela izingxenye, okuqukethwe kwayo okukhethekile kwekhabhoni kuhlanganiswe nokushisela kuqinisekisa ukumelana okuphezulu nokugqwala okujwayelekile, ikakhulukazi okusebenzayo ezingxenyeni ezisindayo.

I-316L ibhekwa njengokumelana kakhulu ne-oxidation kunohlobo 316, ikakhulukazi ezindaweni ezifudumele zasolwandle.Futhi, okuqukethwe kwayo kwekhabhoni ephansi kuyivikela emvuleni ye-carbon.Insimbi iphinde ibonise ukumelana emazingeni okushisa aphansi kakhulu, ngisho naphansi kuya kumazinga we-cryogenic.Mayelana nokumelana nokushisa, i-316L ikhombisa ukumelana nokukhuphuka okungcono, ukumelana nengcindezi yokuphuka kanye namandla aphelele kunamanye amamaki ensimbi engagqwali.

Izinqubo eziningi zokusebenza ezifanayo ezivumelekile ku-Type 316 zingaphinda zisetshenziselwe u-316L, okuhlanganisa ukushisela nokuqina komsebenzi obandayo.Ukwengeza, i-316 ayidingi ukukhishwa kwe-post-service annealing ukuze kwandiswe ukumelana kwayo nokugqwala, kodwa ukudonsa kungase kusetshenziswe kwezinye izimo.

316H/TP316H Insimbi Engagqwali

I-Grade 316H ibhekisela ku-S31609, okuqukethwe kwekhabhoni 0.04% kuya ku-0.10%, inikeza ukumelana nokushisa okuphezulu kuno-316L.

316Ti/TP316Ti

Insimbi engagqwali i-316Ti yaziwa njengebanga elizinzile lohlobo lwe-316 futhi ingenye yezinsimbi ezimbili ezingenasici ezingama-316 ezinconyelwe ukusetshenziswa kwezinga lokushisa eliphakeme.Leli banga liqukethe inani elincane (imvamisa kuphela i-0.5%) ye-titanium.Nakuba isabelana ngezinto eziningi zamanye amabanga angu-316, ukungezwa kwe-titanium kuvikela i-316Ti emvuleni emazingeni okushisa aphezulu, ngisho nokuchayeka isikhathi eside.

I-Molybdenum iphinde yengezwe ekwakhiweni kwe-316Ti.Njengamanye amamaki angu-316, i-molybdenum ihlinzeka ngokuvikeleka okuthuthukisiwe ekugqwaleni, ekufakweni kwesisombululo se-chloride namandla uma ibekwe endaweni yokushisa ephezulu.Kodwa-ke, ukumelana kwayo nezinga lokushisa eliphezulu kuhlanganiswe nokuqukethwe kwayo kwe-titanium, okwenza i-316Ti ingavikeleki emvuleni kulawa mazinga okushisa.Ngaphezu kwalokho, insimbi imelana nama-asidi afana ne-sulfuric acid, i-hydrochloric acid, ne-acid sulfates.
I-316Ti ijwayele ukusetshenziswa kuma-heaters, izinto zokugaya amaphepha kanye nezingxenye zokwakha ezindaweni zasolwandle.

I-TP316LN/316N

I-316N: I-nitrogen (N) yengezwa ku-316 insimbi engagqwali ukuze kwandiswe amandla ngaphandle kokunciphisa ipulasitiki, ukuze ukushuba kwezinto kuncipha.Ukuze uthole izingxenye ezinamandla eziphakeme ezinokumelana nokugqwala okungcono.

I-316LN nayo ingu-316L ene-N, inokumelana nokugqwala okungcono kuno-316N.

I-TP316/316L/316H/316Ti Izicelo Zepayipi Lensimbi Engenasici

Ipayipi le-TP316/316L elingenamthungo lisetshenziselwa ukudluliswa kwengcindezi ye-liquid noma igesi ekuhlanzeni amanzi, ukuhlanza amanzi angcolile, amakhemikhali e-petrochemical, amakhemikhali, ekhemisi nezinye izimboni.Futhi izinhlelo zokusebenza zesakhiwo zihlanganisa ama-handrails, izigxobo kanye nepayipi lokusekela lamanzi anosawoti kanye nezindawo ezibolayo.Uma kuqhathaniswa ne-TP304 yensimbi engagqwali, ipayipi lensimbi engagqwali i-TP316 inokushisela okuphansi, ngakho-ke alisetshenziswa kaningi njengepayipi elishiselwe ngaphandle uma ukumelana nokugqwala kwalo okuphakeme kudlula ukushisela.
