JIS G3125 SPA-Hyog tus txheej txheem kev lag luam Nyij Pooj npog kub- dov huab cua steel daim hlau. Piv nrog cov pa roj carbon steel, SPA-H steel muab kev txhim kho atmospheric corrosion kuj.
Raws li cov khoom siv hlau huab cua, SPA-H steel coil ib txwm tsim muaj kev tiv thaiv oxide patina ntawm nws qhov chaw thaum raug rau ib puag ncig, muab nws qhov txawv rustic zoo li thaum tiv thaiv lub hauv paus hlau.
Cov tshuaj muaj pes tsawg leeg ntawm JIS G3125 SPA-H strip feem ntau muaj cov pa roj carbon, silicon, manganese, phosphorus, sulfur, tooj liab, chromium, thiab nickel.
Cov hlau muaj qhov tsawg kawg nkaus tensile lub zog ntawm 490 MPa thiab qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa, ua rau nws tsim nyog rau kev thov cov qauv siv. SPA-H steel phaj yog dav siv hauv kev tsim kho, kev lag luam, cua preheaters, thiab tsheb ciav hlau.
SPA-H weathering steel ua ke nrog qhov zoo ntawm cov qauv hlau zoo tib yam- xws li kev tsim tau zoo, lub zog siab, thiab kev qaug zog zoo heev - nrog kev txhim kho corrosion kuj zoo. Nws tsis kam rau atmospheric corrosion feem ntau yog 2 mus rau 8 npaug siab dua li cov qauv carbon steel.
Kuj tseem hu ua atmospheric corrosion-cov hlau tsis muaj zog, SPA-H yog qis- alloy hlau nyob nruab nrab ntawm cov hlau tsis muaj steel thiab cov hlau tsis muaj steel. Nws yog tsim los ntawm kev ntxiv cov nqi tswj ntawm tooj liab thiab corrosion-resistant alloying ntsiab xws li phosphorus, chromium, npib tsib xee, titanium, thiab vanadium rau carbon hlau.
Raws li qhov tshwm sim, SPA-H steel tsis tsuas yog khaws cov kev ua haujlwm zoo ntawm cov pa steel xwb, tab sis kuj tseem xa mus ntev - lub sijhawm ua haujlwm nyob rau hauv ib puag ncig sab nraum zoov.
Vim cov khoom zoo tshaj no, SPA-H weathering steel kuj kim heev. Piv nrog cov pa roj carbon zoo tib yam, nws cov nqi lag luam feem ntau yog nyob ib ncig ntawm 60% siab dua.
Yog li ntawd, SPA-H steel feem ntau yog tshwj tseg rau cov ntawv thov nrog cov kev pabcuam hnyav thiab nruj corrosion- cov kev cai tiv thaiv, xws li cov thawv thauj khoom, tsheb ciav hlau, roj derricks, drilling platforms, thiab lwm yam khoom raug.

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
