QN1803 Ibyuma bitagira umuyonga: Imikorere-Yisumbuyeho 304
2025-06-12
Incamake: QN1803 (nanone yitwa 304D cyangwa urwego 1.4376) nicyuma gishya cya austenitike kitagira ibyuma cya Tsingshan / Qingtuo. Yakozwe na azote nyinshi, chromium nini n'umuringa, kandi igabanya nikel kugirango itange imbaraga nyinshi hamwe no kurwanya ruswa ku giciro gitokuruta ibisanzwe 304. QN1803 isobanurwa nk "uburyo buhendutse bushoboka gakondo 304 Icyuma, ”Ituro“Kurwanya ruswa iruta izindi, imbaraga nyinshi, no kurwanya kwambara neza”. Igikoresho cyacyo cya azote nyinshi, nikel nkeya nikel igabanya igiciro cya alloy itabangamiye imikorere. Amavuta yoroshye gutunganya no gusudira, kandi yujuje ubuziranenge mpuzamahanga hamwe nimpamyabumenyi yo mu rwego rwibiryo, bigatuma ikwirakwizwa mu mahanga.
Azote-Yinshi, Nickel-Kuzigama Amavuta
Ubuhanga bwa QN1803 bugenewe imikorere no gukoresha neza. Irimo Cr 17.5–19.5%, Kuri 1.0–3.5%, na N 0,20–0,30%, hamwe na Ntabwo ari 2.0-3.5% gusa (bitandukanye na 8% muri 304). Ibinyuranye, 304 ibyuma ni ~ 18% Cr, 8% Ni, ~ 0.045% N, na ~ 0.1% Cu gusa. Azote yiyongereye hamwe na chromium byongera imbaraga hamwe no guhangana na pitingi, mugihe wongeyeho umuringa utanga antibacterial kandi ikora neza. Nikel yo hasi (na manganese iringaniye) igabanya cyane igiciro cyibikoresho. Muri make, QN1803 murwego rwo hejuru-Ni-kuzigama itanga ibyuma bidafite ingese hamwe na ruswa hamwe nubukanishi bingana cyangwa burenze 304 ku giciro gito.
Imbaraga za mashini no kuramba
QN1803 imurikagurisha ibikoresho bya mehaniki birenze ugereranije na 304. Indangagaciro zisanzwe kumpapuro zikonje (0.5 mm) ni: imbaraga zingana ~ 747 MPa vs 670 MPa kuri 304, kandi zitanga imbaraga ~ 432 MPa vs 290 MPa. Gukomera birarenze (HV 230 vs 165). Kurambura bikomeza kuba hejuru (≈52% vs 59% kuri 304) nubwo imbaraga ziyongera. Mubikorwa bifatika, umusaruro wa QN1803 uri hafi 1.3 × irya 304 mugihe ugumana guhindagurika (kurambura ≥45%). Igisubizo nikintu gikomeye, umunaniro mwinshi- kandi wihanganira kwambara. Irasudira kandi ikora neza: imbaraga za nyuma yo gusudira zihuye cyangwa zirenga 304, kandi gukora ubukonje ntibitesha agaciro ruswa.
Ibyingenzi byingenzi byubukanishi:
-
Imbaraga zikomeye: ~ 747 MPa (vs 670 MPa kuri 304).
-
Imbaraga Zitanga: ~ 432 MPa (vs 290 MPa).
-
Kurambura: ~ 52% (vs 58.5%).
-
Gukomera: HV230 (vs HV165).
Kurwanya Ruswa Kuruta
Amavuta menshi ya Cr na N atanga umusaruro imikorere myiza ya ruswa. QN1803 yo Kurwanya Kurwanya Umubare uhwanye (PREN) urenga 19, uhuye cyangwa urenze 304 yo guhangana (PREN≈18.5). Mu bizamini bisanzwe, QN1803 niyo yerekana byiza Kurwanya ruswa nyuma yo gukonja (kunama, kashe, nibindi) ugereranije na 304. Irwanya cyane acide acide (HCl, H₂SO₄) hamwe nibidukikije birimo chloride. Kurugero, mugupima umunyu-spray (NSS) kubipimo bya GB / T, QN1803 yerekanye nta ngese igaragara nyuma yamasaha 1000. Mu kizamini kimwe 304 mubisanzwe byatangira kubora. Uku kwihanganira umunyu-spray birashimangira QN1803 kwizerwa mubihe bibi byo hanze cyangwa inyanja.
Amakuru ya Ruswa:
-
CYIZA: > 19.0 (304 ifite .5 18.5).
-
Kurwanya umunyu: Nta ngese nyuma ya 1000 h NSS ikizamini.
-
Acide / Chloride: Byerekanwe neza kandi birwanya kurenza 304, na nyuma yo gushingwa
Umutekano wo mu byiciro-Ibyiza na Antibacterial
QN1803 ifite ibiribwa byuzuye kandi iratanga n'ingaruka za antibacterial. Ubuziranenge buke hamwe n’ibyuma biremereye cyane byujuje ubuziranenge bwa EU, Ubudage LFGB na JIS kubikoresho byo mu gikoni nibikoresho byibiribwa. Kuvanga umuringa (~ 1-3.5%) bitanga ibikorwa bikomeye bya mikorobe: ibizamini byerekana igipimo cya> 99.9% cyo kuboneza urubyaro mu masaha 4 (igipimo cya JIS). Hamwe na anti-ruswa irwanya ruswa mubisanzwe ibiryo bya acide / umunyu, QN1803 nibyiza kuri igikoni cyo mu gikoni, ibikoresho byo guteka, ibyombo hamwe nimiyoboro yo hasi. Kurugero, QN1803 yatsinze ibizamini byimuka byigihugu kubutare buremereye kandi irenga 304 mukurwanya saline nkeya. Mubigega byamazi hamwe na sisitemu yisuku, umuringa nawo ufasha kubuza gukura kwa bagiteri, bigatuma amazi yabitswe agira ubuzima bwiza.
Igishushanyo: Ibikoresho byo gutekesha ibyuma. QN1803 irwanya ruswa cyane hamwe nibirimo umuringa-bivanze byujuje ubuziranenge bwibiribwa hamwe na antibacterial (JIS / EU / LFGB) kubikoni nibicuruzwa byisuku.
Porogaramu no Koresha Imanza
QN1803 ikomatanya imbaraga, kurwanya ruswa no gukoresha neza ibiciro bituma ikora byinshi mubikorwa byinshi. Isanzwe ikoreshwa kuri:
Ubwubatsi & Ubwubatsi: Igisenge, imbaho z'urukuta, urukuta rw'umwenda hamwe no kwambika imitako byunguka imbaraga za QN1803 hamwe n’imihindagurikire y’ikirere. Imbaraga nyinshi zo gutanga umusaruro (zirenze icyiciro cyoroheje cyicyuma) zitanga ibipimo byoroheje.
Imiyoboro n'ibikorwa Remezo: Imiyoboro yo gutemba no kuzimya umuriro, amazi, imiyoboro hamwe n’imyanda itwara ubuzima buramba kubera ubudahangarwa bwibyuma byangiza ingese na aside. Mu miyoboro ya gaze cyangwa iminara ya desulfurizasi, QN1803 irwanya ruswa irimo sulfure iruta 304.
Kubika Amazi & Guhinga: Ibigega, ibigega hamwe n’ubuhinzi bwo mu nyanja bifashisha QN1803 kubirimo umuringa wa antibacterial hamwe nigihe kirekire cyamazi yumunyu. Imbaraga zayo kandi ishyigikira imitwaro iremereye mubikoresho byamatungo.
Igikoni n'ibikoresho: Countertops, sinks, ibikoresho byo guteka, hamwe nimashini zibiribwa bikunda QN1803 kubwumutekano wacyo wo mu rwego rwibiryo. Ihanganira acide nkeya hamwe nigikoni cyumunyu mwinshi kuruta 304, kandi yujuje ubuziranenge bwisuku mpuzamahanga.
Abaguzi & Ibicuruzwa byubucuruzi: Inzugi z'ibyuma, imbaho zo hejuru, hamwe na hinges cyangwa gari ya moshi zishushanya gukoresha QN1803 gukomera no kwambara. Ugereranije na 304 mumuryango / amarembo ya porogaramu, QN1803 ikomeza kurangiza no kumiterere bitewe n'ingaruka n'umuyaga. Irasudira kandi ikoza neza ibikoresho n'ibikoresho byo gutwara.
Igishushanyo: Ibyuma by'irembo ibyuma. QN1803 itanga ubukana nimbaraga zirenze 304 kubikoresho byububiko hamwe nubucuruzi, mugihe utanga ruswa irwanya ibidukikije hanze.
Inyungu Zirenga 304 Icyuma
Ugereranije nibisanzwe 304, QN1803 itanga iterambere ryibanze mu bice by'ingenzi:
Ibikoresho bya mashini: Nkuko byavuzwe, imbaraga zacyo kandi zitanga umusaruro uri hejuru ya 15-30% kurenza 304. Ubukomere n'umunaniro ubuzima nabwo buratera imbere, butanga ibice byoroheje cyangwa ibice byoroheje kubikorwa bimwe.
Imikorere ya ruswa: QN1803 ihuye cyangwa irenga 304 irwanya ruswa mubizamini byose. Kurwanya PREN hamwe na sulfurike / chloride irwanya bivuze ko iruta 304 cyane cyane mubihe bikaze cyangwa byakozwe. Irwanya gutobora no gutobora no mu gikoni no mu kirere cyo mu nyanja, bigatuma ihitamo igihe kirekire kubikoresha hanze ndetse no gukoresha ibiryo.
Gukora neza: Bitewe na nikel yo hepfo na azote / umuringa mwinshi, QN1803 irashobora kugura kugeza ~ 20% munsi ya 304 kuri toni (bitewe nisoko) mugihe itanga imikorere ingana cyangwa nziza. Abasesenguzi bavuga ko "ibyo 304 ishobora gukora, 304D nayo irashobora gukora, kandi igiciro gihenze cyane". Igiciro cyo hasi ya alloy hamwe nigihe kirekire cyibigize ubuzima bisobanurwa kugiciro rusange cya nyirubwite.
Ibiribwa / Umutekano w'ubuzima: QN1803 yemerewe gukoresha ibiryo-guhuza. Ibikoresho byayo byongerewe umuringa, bifite isuku nyinshi byatsinze ibizamini bya antibacterial no kwimuka (EU, JIS, LFGB), amanota agera kuri 304 ntashobora. Ibi bituma bikurura cyane cyane igikoni, isuku namazi bisaba umutekano wemewe.
Muri make, QN1803 / 304D ibyuma bidafite ingese bitanga injeniyeri ninzobere mu gutanga amasoko akora cyane, yangiza ibiribwa, kandi bihendutse. Ihuriro ryayo azote nyinshi ivanze, Cr / Cu ndende, Hagati Ni itanga imbaraga za mashini hamwe no kurwanya ruswa ihura cyangwa irenga 304, mugihe uzigama ibiciro bya nikel. Amavuta agaragara ko yizewe mubizamini mpuzamahanga (NSS 1000h, antibacterial JIS, nibindi) hamwe nuburyo bugari bukoreshwa bituma iba inzira yuburyo bwibicuruzwa bigezweho bitagira umwanda.
