Cov khoom siv stainless-feem ntau hu ua stainless hlau- yog ib qho ntawm cov khoom siv ntau yam thiab siv dav hauv kev tsim khoom. Tab sis dab tsi yog cov khoom siv stainless? Ntawm nws cov tub ntxhais, nws yog cov hlau alloy, chromium (tsawg kawg 10.5%), thiab lwm yam (nickel, molybdenum, thiab lwm yam) tsim los tiv thaiv corrosion, xeb, thiab staining. Tsis zoo li cov hlau tsis tu ncua, cov khoom siv tsis zoo tsim cov txheej txheem oxide tiv thaiv ntawm nws qhov chaw, ua rau nws tseem ceeb rau cov ntawv thov uas kav ntev, kev nyiam huv, thiab kev ua neej ntev yog qhov tseem ceeb.
Rau ntau tshaj 15 xyoo,JOYEAR Hlau ua haujlwm tau siv cov khoom siv stainless hlau los ua haujlwm siab -kev ua tau zoo ntawm cov khoom lag luam. Raws li tsev neeg- muaj kev lag luam tsim nyob rau xyoo 2008, JOYEAR ua haujlwm 5, 000+ square meter Hoobkas nrog 300+ cov neeg ua haujlwm txawj, tuav ISO 9001: 2015 (zoo) thiab ISO 14001: 2004 (sustainability) ntawv pov thawj. Lawv cov khoom siv stainless hlau-xws li SS304 nruam hinges, stainless hlau forklift Cheebtsam, thiab kev cai ntawv hlau fabrications- ua tau raws li cov qauv thoob ntiaj teb (ISO 2330, ANSI/ITSDF B56.11.4) thiab pab 100+ cov neeg siv khoom thoob ntiaj teb hla kev thauj mus los, kev tsim kho, marine, thiab hluav taws xob.
Hauv phau ntawv qhia no, peb yuav txhais cov khoom siv stainless, rhuav tshem nws cov khoom tseem ceeb, tshawb nrhiav ntau hom, thiab qhia tias JOYEAR qhov kev txawj ntse hauv cov khoom siv stainless muab cov kev daws teeb meem zoo li cas. Thaum kawg, koj yuav nkag siab meej tias cov khoom siv stainless hlau yog dab tsi, vim li cas nws yog qhov tseem ceeb rau kev lag luam kev vam meej, thiab vim li cas JOYEAR yog ib tus neeg ntseeg siab rau cov khoom siv stainless hlau.
1. Cov Khoom Siv Stainless Hlau yog dab tsi? Core txhais & Kev sib xyaw
Cov khoom siv stainless yog ib tsev neeg ntawm cov hlau-raws li alloys txhais los ntawm ob yam tsis yog- sib tham tau: yam tsawg kawg nkaus 10.5% chromium cov ntsiab lus, thiab muaj peev xwm tsim ib tug passive (tiv thaiv) oxide txheej thaum raug oxygen. Cov txheej no yog dab tsi teeb nws sib nrug los ntawm cov hlau tsis tu ncua thiab muab nws corrosion kuj.
1.1 Chemical Composition
- Hlau (Fe): Lub hauv paus hlau (60-70% ntawm cov muaj pes tsawg leeg), muab cov qauv tsim muaj zog.
- Chromium (Cr): 10.5–30% ntawm cov muaj pes tsawg leeg- hnov mob nrog oxygen los ua ib txheej nyias, tsis pom chromium oxide txheej (passive txheej) uas thaiv xeb thiab xeb.
- Nickel (Ni): 8–22% (hauv cov qib austenitic xws li 304/316)- txhim kho ductility, corrosion resistance, thiab qis-kub kev ua haujlwm.
- Molybdenum (hli): 2–3% (hauv qib zoo li 316)- txhawb nqa cov dej ntsev, kua qaub, thiab cov tshuaj hnyav.
- Cov pa roj carbon (C): <0.08% (in low-carbon grades like 304L)-reduces the risk of "sensitization" (corrosion at high temperatures).
JOYEAR tseem ceeb tshaj - cov khoom tsis zoo rau nws cov khoom. Piv txwv li, lawvSS304 nruam hingessiv 18% chromium thiab 8% npib tsib xee, kom ntseeg tau zoo corrosion kuj rau sab nraum zoov thiab marine daim ntaub ntawv.
1.2 The Passive Layer: Vim li cas Cov Khoom Siv Stainless tsis xeb
Cov khawv koob ntawm stainless cov khoom nyob rau hauv nws passive oxide txheej:
- Thaum chromium reacts nrog oxygen (cua lossis dej), nws tsim 0.000001mm- txheej tuab ntawm qhov chaw.
- Cov txheej no nws tus kheej- kho: yog khawb lossis puas, chromium nthuav tawm tam sim ntawd hloov txheej txheej - tiv thaiv xeb los ntawm kev nkag mus rau hauv lub hauv paus hlau.
- Yog tias tsis muaj chromium txaus (tsawg dua 10.5%), txheej txheej tsis tuaj yeem tsim, thiab cov khoom coj zoo li cov hlau tsis tu ncua (xws li xeb).
JOYEAR qhov kev tswj xyuas zoo ua kom lawv cov khoom siv stainless hlau khaws cov txheej txheem no: lawv cov stainless hlau forklift qhov chaw tau txais kev tshuaj ntsuam ntsev ntsev (500+ teev) txhawm rau txheeb xyuas qhov kev tiv thaiv corrosion, tseem ceeb rau cov tsev khaws khoom thiab cov chaw nyob hauv ntug dej hiav txwv.
