SPA-H weathering steel phaj, teev nyob rau hauv JIS G3125, yog siab -lub zog qis- alloy steel tsim rau ntev - lub sij hawm raug rau atmospheric ib puag ncig.
Nws cov ntsiab lus alloying- tooj liab (0.25–0.55%), chromium (0.30–0.70%), npib tsib xee (0.30–0.50%), thiab phosphorus- pab tsim kom muaj qhov ntom ntom, tiv thaiv oxide txheej (patina), uas txo cov nqi corrosion.
Cov hlau phaj tuav cov khoom zoo heev thaum muab cov khoom zoo weldability, formability, thiab ua tau yooj yim (txiav, dabtsi yog khoov, dov).
SPA-H yog dav siv nyob rau hauv txuas hniav, thawv, tsheb, architectural facades, siv machinery, thiab cia tank, muab lub sij hawm ntev - durability, tsis tshua muaj txij nkawm, thiab structural ntseeg nyob rau hauv hnyav sab nraum zoov ib puag ncig.

Daim ntawv thov ntawm SPA-H Weathering Steel Phaj
SPA-H weathering steel phaj yog dav siv nyob rau hauv kev lag luam thiab tej yaam num uas ntev - lub sij hawm durability, siab zog, thiab atmospheric corrosion kuj tseem ceeb heev. Nws cov ntawv thov suav nrog:
Choj Structures thiab Infrastructure Projects: SPA-H feem ntau yog siv rau choj girders, trusses, thiab kev txhawb nqa cov qauv vim nws lub zog tawm los siab (Ntau dua lossis sib npaug rau 345 MPa) thiab zoo heev corrosion kuj. Lub ntuj tsim xeb patina tiv thaiv cov hlau los ntawm atmospheric degradation, txo kev txij nkawm thiab ncua kev pab cuam lub neej ntawm cov choj nyob rau hauv huab cua hnyav, nrog rau cov ntug hiav txwv dej thiab kev lag luam ib puag ncig.
Shipping Containers, Storage Tanks, thiab Hoppers: Cov hlau zoo tshaj plaws huab cua tiv thaiv ua rau nws zoo tagnrho rau cov thawv ntim khoom, lub tank cia, silos, thiab hoppers raug los nag, av noo, thiab kub hloov pauv. SPA-H's corrosion-cov khoom tiv thaiv pab tiv thaiv cov khoom siv degradation, txo nqi kho thiab rov ua dua tshiab, thaum tuav cov txheej txheem kev ncaj ncees rau ntau xyoo ntawm kev siv tsis tu ncua.
Railway thiab Automotive Cheebtsam: SPA-H weathering steel phaj yog siv nyob rau hauv railway carriages, locomotives, thiab hnyav- lub luag hauj lwm automotive thav duab uas muaj zog thiab toughness yog qhov tseem ceeb. Nws lub zog tensile siab thiab ruaj khov elongation kom muaj kev ruaj ntseg nyob rau hauv dynamic loads thiab kev co, thaum lub xeb patina muab ib tug tiv thaiv tiv thaiv corrosion thaum lub sij hawm sab nraum zoov ua hauj lwm.
Architectural Facades thiab Cladding: Qhov txawv reddish -xim av patina ntawm SPA-H steel tau ua rau nws yog ib qho kev xaiv nrov rau lub tsev sab nrauv, kab hlau rhuav phab ntsa, thiab kho kom zoo nkauj cladding. Tshaj li kev zoo nkauj, cov khoom muaj kev saib xyuas qis, ntev - lub sij hawm durability, thiab tsis kam mus rau lub nroog muaj kuab paug, combining pom kev pom zoo nrog kev tiv thaiv huab cua. Nws yog haum rau ob qho tib si niaj hnub thiab industrial architectural styles.
Kev Tsim Kho Machinery thiab Cov Khoom Siv Khoom Siv: SPA-H steel yog ua haujlwm hauv cov tshuab hnyav, cranes, conveyors, thiab lwm yam khoom siv hauv kev lag luam uas muaj kev thauj khoom siab -cov kabmob muaj peev xwm thiab raug rau sab nraum zoov. Kev sib xyaw ua ke ntawm kev tiv thaiv corrosion, toughness, thiab weldability kom ntseeg tau tias cov khoom muaj kev ua haujlwm zoo txawm tias nyob rau hauv ib puag ncig nyuaj ua haujlwm.

SPA-H weathering steel phaj sib txuas ua ke ntev- lub sij hawm durability, zoo nkauj txaus siab, thiab tsis tshua muaj txij nkawm, ua rau nws zoo tagnrho rau kev siv nyob rau hauv hnyav sab nraum zoov ib puag ncig uas yuav tsum tau muaj zog thiab corrosion kuj.
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 suav nrog kev ua haujlwm zoo ntawm huab cua corrosion, 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
