1. Alloy Tsim: Corrosion-resistant ntsiab
Spa-c muaj cov khoom sib txuas zoo ntxiv ntawmtooj liab (cu), chromium (cr), phosphorus (p), thiab npib tsib caug (ni), uas ua haujlwm ua ke los ua qhov ruaj khov, tiv thaiv kab xeb:
CU (0.25-0.55%): Txhawb kev tsim cov roj deg ntom nti, txhim kho cov khoom siv tshuab corrosider tsis kam.
CR (0.30-1.25%): Tsim ib qho kev sib tw oxide passion oxide (zoo ib yam li tus hlau stainless tab sis thinner).
P (0.07–0.15%): Ua kom nrawm dua qhov tsim ntawm lub ntsej muag nruj me ntsis patina.
Ni (kab cim): Txhim kho kev nruj thiab ntev ntev nyob hauv ib puag ncig kev sib zog.
Sib piv rau Cov Hlau Hlau: Txheej Txheem Hlau Steel Porous, Flaky Rust uas nrawm dua corrosion, thaum spa-c los tsim cov txheej txheem oxide helfing.
2. Kev tiv thaiv Patina tsim cov txheej txheem
Theem 1: Thawj zaug xeb sau (zoo ib yam li cov hlau hlau).
Theem 2: Alloying cov ntsiab kev hnov nrog noo noo thiab oxygen los tsimFesooh Cucro₂Tebchaw, sib sau ua cov txheej xim av tsaus nti.
Qho kawg: Lub patinatseem ceeb slows ntxiv corrosion(Raug corrosion tus nqi:0.002-0.005 mm / xyoovs.0.1+ hli / xyooRau cov hlau hlau).
Qhov Tseem Ceeb: Tshem tawm qhov xav tau kev pleev xim nyob rau hauv feem ntau ib puag ncig, drastically txo cov nqi kho.
3. Kev siv kho lub zog & kev nruj
SPA-C tswj hwm cov qauv txheej txheem hauv txoj kev ntxhov siab:
Lub zog tensile: 490-620 mpa (siab dua cov hlau me me).
Kev Cuam Tshuam: Khaws cov tawv tawv txawm tias ntawm qhov kub tsawg (piv txwv li, -20 degree).
Cov Kev Siv Raug Raug: Txuas hniav (piv txwv li, Nyiv tus xov tooj ntawm Shead), cov thawv xa khoom, thiab cov kws kos duab.
4. Ib puag ncig kev yoog tau
Nroog / Chaw Muaj Kev Lag Luam: Resards corrosion los ntawm so₂ thiab Nox polled.
Cov ntug hiav txwv: Ua tau zoo dua li cov roj carbon hlau hauv qab cov ntsev tsuag (txawm tias tsis zoo li steel hlau).
Tsab ntawv: Hauv kev ntub dej tsis tu ncua lossis cov chloride ib puag ncig (piv txwv li, dej hiav txwv dej hiav txwv), yuav tsum muaj lub tsho tiv nag dej ntxiv.

6. Txwv tsis pub
Thawj zaug xeb dej: Tej zaum yuav ua rau cov dej xeb xeb rau thawj 2-3 xyoos (yuav tsum tau dej ua kom dej).
Tsis tsim nyog rau: Tshuaj lom neeg raug tshuaj (acids / alkalis) lossis cov ntawv thov ua txhaum loj (piv txwv li, conveyor siv tawv).

SPA-C qhov tshwj xeeb depability stems los ntawm nwsAlloy-Enhanced tiv thaiv Patina, Siab Zog, thiabYuav tsum tau saib xyuas tsawg, ua rau nws zoo tagnrho rau kev siv ntev qauv thiab kev siv hauv cov chaw muaj kev nyab xeeb.
