Q550nhure steel qhia cov txiaj ntsig tseem ceeb tshaj qhov pom zoohigh - muaj zog tsawg -}} alloy cov hlau (hsla)Hais txog huab cua Kuj, feem ntau yog vim nws tus kheej alloy tsim thiab tus kheej -}}} tiv thaiv corrosion. Ntawm no yog cov ncauj lus piav qhia ntawm nws cov txiaj ntsig tseem ceeb:
1. Kev tiv thaiv kab xeb
Q550NH:
Cov qauv ntom ntom, adherentlub moo plaub(xeb txheej) muaj los ntawmCu / cr / ni -}}} Enriched oxidesuas ua raws li kev thaiv kev tiv thaiv kev xeb ntxiv.
Lub patina ruaj khov nyob hauv6-24 lub hlis, txo tus nqi corrosion rauTsawg dua los yog sib npaug rau 0.002 mm / xyooNyob rau hauv cov neeg nyob hauv nroog / Nroog Umospheres.
HSLA hlau:
Rust txheej yog ntxig thiab flaky, tso cai rau kev nkag mus txuas ntxiv ntawm noo noo / oxygen, ua rau muaj kev vam meej thinning.
2. Alloying cov ntsiab lus rau corrosion tsis kam
Q550NH:
Tooj Liab (0.25-0.55%): Catalyzes hnav khaub ncaws tsis muaj xeb nucleation.
Chromium (0.40-0.80%): Txhim kho kev ruaj khov nyob rau hauv acidic / pureded ib puag ncig.
Npib tsib xee (tsawg dua los yog sib npaug rau 0.65%): Txhim kho kev tiv thaiv mus rau chloride rau chloride - induced pitting (tseem ceeb rau cov ntug hiav txwv).
HSLA hlau:
Feem ntau tsis muaj cov ntsiab lus siv, cia siab rauXim lossis pleev ximrau kev tiv thaiv corrosion.
3. Ntev -} sij hawm tu
Q550NH:
Tshem tawm cov kev xav taudaim duabTom qab PATINA stabilization, txiav lub neej nyob los ntawm30–50%tiv thaiv cov xim hatsla steel.
Ua tau zoo hauvKev lag luam / Nqaum huab cua(ISO 9223 chav kawm c3-c4).
HSLA hlau:
Toob kasKev Rov Ua Dua Tshiab(Txhua 5-10 xyoo) los tiv thaiv corrosion tsis ua hauj lwm.
4. Kev ua yeeb yam nyob rau hauv cov chaw hnyav
Vaum huab cua huab cua: Q550NH's patina tiv siab cyclic ntub - dry corrosion zoo dua HSLA cov hlau.
Kuab paug nroog / chaw nyob: CR / NI cov ntsiab lus Mitigates acid los nag (so₂) thiab kev sib tw puas tsuaj.
De -} icing ntsev rau kis: Outperforms HSLA hlau nyob rau hauv txoj kev / Kev Siv Cov Kev Thauj Khoom (piv txwv li, choj, kos npe).
5. Aesthetic thiab Cov Txheej Txheem Kev Ntseeg
Lub patina muab kev sib xws, kos duab kos duab kom tiav tiav, tsis zoo li HSLA cov hlau uas qhia tsis xeb xeb.
Txawm tias nrog nto xeb, q550NH khaws ciaNtau dua los yog sib npaug rau 550 mpa kom muaj zog, thaum corroded HSLA hlau yuav raug kev txom nyem rau cov thinning.
