QN1803 Stainless Simbi: Yakakwirira-Kuita Alternative kune 304
2025-06-12
Muchidimbu QN1803 (inonziwo 304D kana giredhi 1.4376) ichangobva kugadzirwa austenitic Stainless simbi kubva kuTsingshan/Qingtuo. Yakagadzirwa neiyo yakakwira nitrogen, yakakwira chromium uye mhangura, uye yakaderedzwa nickel yemukati kuendesa simba rakakwirira uye kusagadzikana kwemarara pamutengo wakadererakupfuura mwero 304. QN1803 inotsanangurwa se“imwe nzira inodhura kune yechinyakare 304 Stainless Simbi,” kupa"yepamusoro corrosion resistance, simba rakawanda, uye yakanakisa kupfeka kuramba". Yayo yakakwirira-nitrogen, yakaderera-nickel dhizaini inodzikisa alloy mutengo pasina kukanganisa kuita. Iyo alloy iri nyore kugadzira uye weld, uye inosangana nezviyero zvepasi rose uye chikafu-giredhi zvitupa, zvichiita kuti ive yakakodzera kutengeswa kunze kwenyika.
High-Nitrogen, Nickel-Saving Alloy Kuumbwa
QN1803's chemistry yakagadzirirwa kuita uye mutengo-kubudirira. Rine Cr 17.5–19.5%, Ne 1.0–3.5%,uye N 0.20–0.30%, pamwe Kwete kunyange 2.0–3.5% (zvichipikisa ~ 8% mu304). Kusiyana neizvi, 304 simbi ndeye ~ 18% Cr, 8% Ni, ~ 0.045% N, uye chete ~ 0.1% Cu. Iyo yakawedzera nitrogen uye chromium inowedzera simba uye pitting kuramba, nepo yakawedzerwa mhangura inopa antibacterial zvivakwa uye nani kuumbwa. Yakaderera nickel yemukati (uye ine mwero manganese) inoderedza zvakanyanya mutengo wezvinhu. Muchidimbu, QN1803's high-Ni-saving formula inobereka simbi isina tsvina ine ngura uye mechanical maitiro akaenzana kana nani kupfuura 304 pamutengo wakaderera wealloy.
Mechanical Simba uye Kusimba
QN1803 zviratidzo yepamusoro michina zvinhu zvichienzaniswa ne 304. Mamiriro ezvinhu epapepa anotonhora-akakungurutswa (0.5 mm) ndeaya: simba rekusimba ~ 747 MPa vs 670 MPa ye304, uye goho simba ~ 432 MPa vs 290 MPa. Kuoma kwakafanana kwakakwira (HV 230 vs 165). Elongation inoramba yakakwira (≈52% vs 59% ye304) kunyangwe kune simba boos. Mukutaura kwekuita, goho reQN1803 riri pamusoro 1.3× iyo ye304 ichichengetedza ductility (elongation ≥45%). Mhedzisiro yacho ndeye kusimba, kuneta kwakawanda- uye kusapfeka-kusapfeka zvinhu. Iyo zvakare inokwenenzvera uye inoumba zvakanaka: post-weld simba machisi kana kupfuura 304, uye kutonhora-kuumba hakudzikisi corrosion resistance.
Key Mechanical Data:
-
Tensile Simba: ~747 MPa (vs 670 MPa ye304).
-
Goho Simba: ~432 MPa (vs 290 MPa).
-
Elongation: ~52% (vs 58.5%).
-
Kuoma: HV230 (vs HV165).
Superior Corrosion Resistance
Iyo alloy yakakwira Cr uye N inogadzirwa yakanakisa corrosion performance. QN1803's Pitting Resistance Equivalent Number (PREN) inodarika 19, inoenderana kana kupfuura 304's kuramba (PREN≈18.5). Mune yakajairwa bvunzo, QN1803 inotoratidza nani corrosion resistance mushure mekutonhora kuumba (kukotama, kutsika, nezvimwewo) zvichienzaniswa ne 304. Inonyanya kurwisana ne dilute acids (HCl, H₂SO₄) uye chloride-containing environments. Semuyenzaniso, mukusarerekera munyu-spray (NSS) kuyedzwa paGB/T zviyero, QN1803 yakaratidza pasina ngura inooneka mushure memaawa 1000. Muyedzo imwecheteyo 304 yaiwanzotanga kuita ngura. Uku kutsungirira kwepamusoro kwemunyu-spray kunosimbisa kuvimbika kweQN1803 mumamiriro ezvinhu akaoma ekunze kana emugungwa.
Corrosion Data:
-
MUNDA: >19.0 (304 ine ≈18.5).
-
Munyu-Pray Resistance: Hapana ngura mushure me1000 h NSS bvunzo.
-
Acid/Chloride: Yakaratidza zvirinani yunifomu uye pitting kuramba kupfuura 304, kunyangwe mushure mekugadzira
Kudya-Giredhi Kuchengeteka uye Antibacterial Properties
QN1803 yakazara chikafu-yakachengeteka uye inopa yakavakirwa-mukati antibacterial maitiro. Iyo yakanyanya kuchena uye yakaderera-heavy-metal mazinga anosangana neEU, yeGerman LFGB uye JIS zviyero zvekitchenware nemidziyo yechikafu. Copper alloying (~ 1-3.5%) inopa yakasimba antimicrobial chiito: miedzo inoratidza > 99.9% sterilization rate mukati maawa mana (JIS standard). Yakasanganiswa neakanakisa corrosion kuramba mune yakajairwa chikafu acids / munyu, QN1803 yakanakira countertops yekubikira, cookware, singi uye pasi madhiraini. Semuenzaniso, QN1803 inopasa bvunzo dzekutama kwenyika dzesimbi dzinorema uye dzinopfuura 304 mune isina kusimba-asidhi saline kuramba. Mumatangi emvura uye masisitimu ehutsanana, mhangura inobatsirawo kudzivirira kukura kwebhakitiriya, ichiita kuti mvura yakachengetwa ive noutano.
Mufananidzo: Stainless-steel cookware set. QN1803's high corrosion resistance and copper-alloy content inosangana ne-strient food-grade and antibacterial standards (JIS/EU/LFGB) yekicheni uye zvigadzirwa zvehutsanana.
Zvishandiso uye Mamiriro Ekushandisa
QN1803's musanganiswa wesimba, corrosion resistance uye mutengo-kushanda kunoita kuti iite zvakasiyana mumaindasitiri mazhinji. Yave kutoshandiswa ku:
Kuvaka & Architecture: Denga, mapaneru emadziro, madziro emaketeni uye yekushongedza yekushongedza inobatsira kubva kuQN1803 yakasimba simba uye kuramba mamiriro ekunze. Kusimba kwegoho repamusoro (kupfuura zvinyoro zvinyoro simbi mamakisi) inobvumira kureruka geji mapaneru.
Piping uye Infrastructure: Mapombi emvura uye ekudzimisa moto, pombi dzemvura, marata uye masisitimu esuweji anowana hupenyu hurefu nekuda kwekudzivirira kwesimbi kune ngura nekuora kweasidhi. Mumapombi egasi kana desulfurization shongwe, QN1803 inopikisa sulfuri-ine corrosion zviri nani kupfuura 304.
Kuchengeta Mvura & Kurima: Matangi, matangi uye zvivakwa zvekurima zvemugungwa zvinoshandisa QN1803 kune yayo antibacterial mhangura yemukati uye kugara kwemvura yemunyu. Simba rayo rinotsigirawo mitoro inorema mumidziyo yezvipfuwo.
Kicheni uye Zvishandiso: Macountertops, sink, cookware, uye muchina wechikafu anofarira QN1803 yekuchengetedza kwayo-giredhi rekudya. Inoshingirira maasidhi asina kusimba uye nzvimbo dzekicheni ine saline zviri nani pane 304, uye inosangana nemiyero yehutsanana yepasirese.
Consumer & Commercial Products: Magonhi eHardware, mapaneru ekusimudza, uye mahinji ekushongedza kana njanji anoshandisa QN1803 kuomarara kwepamusoro uye kuramba kupfeka. Kuenzaniswa ne304 mumasuo / gedhi zvikumbiro, QN1803 inochengetedza kupera uye chimiro pasi pesimba uye mitoro yemhepo. Inokwenenzverwa nekukwenenzvera zvakanaka midziyo yemagetsi nemidziyo yekutakurisa.
Mufananidzo: Stainless-simbi gedhi hardware. QN1803 inopa kuoma kwepamusoro uye simba kupfuura 304 yezvivakwa zvekugadzira uye zvekutengesa zvigadziriso, uku ichipa yakakwira corrosion kuramba munzvimbo dzekunze.
Zvakanakira Pamusoro pe304 Stainless Simbi
Kuenzaniswa neyakajairwa 304, QN1803 inopa kuvandudzwa kunocherechedzwa munzvimbo dzinokosha:
Mechanical Properties: Sezvacherechedzwa, simba rayo rekusimba uye goho rinenge 15–30% yakakwirira kupfuura 304's. Hupenyu hwekuoma uye kuneta hunovandudzwa zvakare, zvichibvumira zvikamu zvakatetepa kana zvikamu zvakareruka zvekushanda kwakafanana.
Corrosion Performance: QN1803 inofanana kana inodarika 304's corrosion resistance mune zvese bvunzo. Yayo yakakwirira PREN uye sulfuric/chloride kuramba inoreva kuti inodarika 304 kunyanya mumamiriro ehutsinye kana akaumbwa. Inopikisa gomba uye kukoromoka kwegora kunyangwe mukicheni uye mumhepo yemugungwa, zvichiita kuti ive sarudzo yakasimba kune yekunze uye ine chekuita nechikafu.
Kubudirira Kwemari: Kutenda kune yakaderera nickel uye yakakwirira nitrogen / mhangura, QN1803 inogona kudhura kusvika ~ 20% isingasviki 304 patani (zvichienderana nemusika) ichipa zvakaenzana kana zvirinani kuita. Vaongorori vanoti "izvo 304 inogona kuita, 304D inogonawo kuita, uye mutengo wakachipa zvakanyanya". Mutengo wakaderera wealloy uye hupenyu hurefu hwechikamu zvinoshandura kudzikisira mutengo wemuridzi.
Zvokudya/Kuchengetedza Utano: QN1803 inopihwa chitupa chekushandisa-chikafu. Yayo yemhangura-inosimudzira, yakakwirira-kuchena kuumbwa inopfuura yakasimba antibacterial uye migration bvunzo (EU, JIS, LFGB), iyo mamwe 304 mamakisi haagone. Izvi zvinoita kuti iwedzere kutaridzika kukicheni, hutsanana uye mvura yekushandisa inoda certified kuchengetedzwa.
Muchidimbu, QN1803/304D simbi isina tsvina inopa mainjiniya nenyanzvi dzekutenga zvinhu zvemhando yepamusoro, kuchengetedzwa kwechikafu, uye zvinodhura. Kusanganiswa kwayo yakakwira nitrogen alloying, yakakwira Cr/Cu, yepakati Ni inoipa simba remagetsi uye kusagadzikana kwekuora kunosangana kana kudarika 304's, uku uchichengetedza mari yenickel. Iyo alloy yakaratidza kuvimbika muyedzo dzepasirese mwero (NSS 1000h, JIS antibacterial, nezvimwewo) uye huwandu hwayo hwekushandisa hunoita kuti ive nzira yakasarudzika yezvigadzirwa zvemazuva ano zvesimbi.
