SPA-Hthiab SPA-C steel daim hlau yog siab-kev ua tau zoo huab cua steels teev nyob rau hauv JIS G 3125, dav lees paub rau lawv zoo heev atmospheric corrosion kuj thiab ruaj khov txhua yam khoom.
When exposed to air and moisture, both grades form a dense and adherent rust patina that significantly slows further corrosion. Qhov kev tiv thaiv tus kheej no tshem tawm lossis txo qis qhov xav tau ntawm kev pleev xim thiab kev saib xyuas ib ntus, ua rau SPA-H thiab SPA-C cov ntaub ntawv zoo tshaj plaws rau kev pabcuam sab nraum lub sijhawm ntev.
Piv nrog rau cov pa roj carbon zoo tib yam, SPA-H thiab SPA-C muaj kev tiv thaiv zoo tshaj plaws rau atmospheric corrosion, tshwj xeeb tshaj yog nyob rau hauv industrial, nroog, thiab infrastructure ib puag ncig, pab txo cov nqi lifecycle thiab txo ib puag ncig cuam tshuam nrog coatings thiab repainting.
Tej kev siv
SPA-H thiab SPA-C steel daim hlau yog dav siv nyob rau hauv tej yaam num uas yuav tsum tau muaj ob qho tib si lub cev muaj zog thiab ntev -lub sij hawm huab cua tsis kam, xws li:
Kev tsim cov thawv ntim khoom: cov qauv vaj huam sib luag thiab cov thav duab raug rau sab nraum zoov cia thiab thauj ib puag ncig
- Choj thiab kev tsim kho vaj tse: girders, decks, guard panels, thiab structural Cheebtsam
- Automotive thiab railway tsheb: wagon lub cev, underframes, thiab sab nrauv yam ntxwv
- Architectural cladding thiab façades: phab ntsa panels, cov ntxaij vab tshaus, thiab cov hniav zoo nkauj sab nrauv
- Sab nraum zoov cia tso tsheb hlau luam thiab cov cuab yeej muaj: vaj tse, enclosures, thiab load-cov kabmob
Lawv lub peev xwm los tswj cov txheej txheem kev ncaj ncees yam tsis muaj repainting ntau zaus ua rau lawv tshwj xeeb tshaj yog haum rau cov haujlwm tsim los rau ntau xyoo ntawm kev pabcuam lub neej.

Q1: Dab tsi yog SPA-H Corten steel?
SPA-H yog cov txheej txheem Nyij Pooj huab cua hlau qib uas tau teev tseg hauv JIS G 3125. Nws muaj cov ntsiab lus alloying xws li tooj liab, chromium, thiab npib tsib xee, uas tso cai rau nws los tsim cov txheej txheem tiv thaiv xeb ntawm qhov chaw. Qhov patina no ua rau qeeb ntxiv corrosion thiab txhim kho ntev -lub sij hawm durability nyob rau hauv atmospheric ib puag ncig.
Q2: Dab tsi yog qhov zoo ntawm SPA-H weathering steel?
Cov txiaj ntsig tseem ceeb ntawm SPA-H steel muaj xws li cov huab cua zoo corrosion kuj, siab zog, thiab tus nqi tu qis. Tsis zoo li cov pa roj carbon zoo tib yam, SPA-H tsis tas yuav tsum tau pleev xim ntau dhau los yog txheej txheej, uas yuav pab txo qis cov nqi ntawm lub neej thaum tuav lub cev zoo nkauj.
Q3: SPA -H Corten steel feem ntau siv nyob qhov twg?
SPA-H hlau yog dav siv nyob rau hauv cov txuas hniav, lub tsev cov qauv, architectural façades, railway carriages, ntim, cua preheaters, thiab economizers. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov qauv sab nraum zoov uas raug hloov pauv huab cua rau lub sijhawm ntev.
Q4: Puas yog SPA-H steel xav tau kev pleev xim lossis kho qhov chaw?
Hauv feem ntau cov ntawv thov sab nraum zoov, tsis tas yuav tsum tau pleev xim ntxiv. SPA-H ib txwm tsim txheej txheej xeb ruaj khov tom qab raug rau qhov chaw. Txawm li cas los xij, nyob rau hauv ib puag ncig corrosive heev (xws li marine los yog siab - thaj chaw ntsev), ntxiv kev tiv thaiv saum npoo tuaj yeem raug pom zoo kom txuas lub neej ua haujlwm.
Q5: Nws siv sijhawm ntev npaum li cas rau SPA-H steel los tsim patina ruaj khov?
Nyob rau hauv cov huab cua ib puag ncig, SPA-H steel feem ntau tsim cov patina ruaj khov hauv 6 txog 24 lub hlis
