JIS SPA-H Corten Steel Description
JIS G 3125 SPA-Hyog lub ntiaj teb no -nrov kub kub- dov weathering structural steel, dav lees paub tias yog thawj qhov sib npaug rauCorten A. Nrog rau qhov tsawg kawg nkaus lub zog ntawm 345 MPa thiab tshwj xeeb atmospheric corrosion tsis kam (tsav los ntawm Cu, Cr, thiab P), nws yog cov khoom siv tsis sib haum xeeb rau kev tsim ISO shipping ntim, railway wagons, thiab architectural facades.

1. Qhov Kev Ua Tau Zoo: Vim Li Cas Xaiv SPA-H?
Tsis zoo li cov pa roj carbon steel, SPA-H tso siab rau qhov tshwj xeeb "carbon steel + corrosion-cov alloys resistant" system. Qhov ntxiv ntawmCopper (Cu), Chromium (Cr), thiab Phosphorus (P)ua haujlwm synergistically txhawm rau txhawm rau tsim kom muaj qhov ntom ntom, ruaj khov oxide xeb txheej. Cov patina no tiv taus kev yaig los ntawm huab cua noo thiab huab cua hauv hiav txwv, tso cai rau SPA-H siv liab qab (tsis muaj xim) nyob rau hauv huab cua sov thiab subtropical ib puag ncig.
Rau ib puag ncig marine corrosive heev, sib txuas SPA-H nrog phosphating kev kho mob thiab fluorocarbon xim tuaj yeem txuas ntxiv nws lub neej kev pabcuam.
2. Standard Cross-Reference: SPA-H vs. Q355GNH vs. S355J0WP
(Ib Daim Ntawv Qhia Txog Kev Tsim Kho Tseem Ceeb rau Kev Hloov Hloov Hloov)
Thaum nrhiav huab cua hlau thoob ntiaj teb, cov neeg yuav khoom nquag nug seb SPA-H tuaj yeem hloov cov qauv European lossis Suav. ThaumSPA-H, qw 355g, thiabS355J0 wbtag nrho yog nyob rau nruab nrab - siab zog weathering steel tsev neeg (yield zog nyob ib ncig ntawm 355 MPa),qhov sib txawv tseem ceeb nyob hauv lawv qhov qis -kub qhov cuam tshuam toughness.
Raws li cov qauv kev xaiv cov khoom siv engineering, ntawm no yog qhov lawv sib piv:
| Standard System | Qib Steel | Yield zog | Impact Toughness (Test Temp) | Ib puag ncig zoo tshaj plaws |
| Nyiv (JIS G 3125) | SPA-H | Ntau dua lossis sib npaug li 345 MPa | Ntau dua lossis sib npaug li 27 J ntawm-10 degree | Temperate & Subtropical Regions |
| Teb chaws Europe (EN 10025-5) | S355J0 wb | Ntau dua lossis sib npaug li 355 MPa | Ntau dua lossis sib npaug li 27 J ntawm0 degree | Thaj tsam huab cua |
| Tuam Tshoj (GB/T 4171) | qw 355g | Ntau dua lossis sib npaug li 355 MPa | Ntau dua lossis sib npaug rau 34 J ntawm-20 degree | Txias & Freezing Regions |
Cov tswv yim hloov pauv tus kws tshaj lij:
Yog tias koj qhov project nyob rau hauv ib puag ncig huab cua lossis thaj chaw sov sov (xws li Cov Neeg Esxias Qab Teb Hnub Tuaj lossis Middle East), SPA-H thiab S355J0WP tuaj yeem siv sib hloov. Txawm li cas los xij, yog tias koj qhov phiaj xwm nyob hauv thaj chaw txias heev (qhov ntsuas kub tsawg kawg tsawg dua lossis sib npaug li -20 degree), koj yuav tsum ua qhov tseem ceeb rau Suav teb tus qauv.qw 355g, raws li nws muaj qhov zoo tshaj plaws qis -kub toughness.
3. Sab saum toj 4 Tus Neeg Yuav Khoom Kev txhawj xeeb & FAQs (Koj yuav tsum paub dab tsi ua ntej yuav)
Raws li ib tug ua lag luam ntawm weathering steel, peb nkag siab cov ntsiab lus mob ntawm lub thawv manufacturers thiab cov qauv engineers. Nov yog cov lus teb rau koj cov kev txhawj xeeb tseem ceeb tshaj plaws:
Q1: Koj tswj cov thickness kam rau ua li cas rau SPA-H coils/plates?
A (Qhov Nyhav & Tus Nqi Txaus Siab):Rau shipping thawv manufacturers, pes tsawg thickness (piv txwv li, 1.6mm, 2.0mm) yog ib qho tseem ceeb. Yog tias qhov tsis zoo siab ntev dhau lawm, lub thawv yuav ua tsis tiav cov kev xeem; yog tias qhov zoo, qhov hnyav tuag nce, raug nqi koj cov nyiaj. Peb nruj me ntsis tswj covtsis zoo kam rau uaThaum lub sij hawm kub- dov txheej txheem kom ntseeg tau tias koj cov kab ntau lawm ua haujlwm tau zoo thiab koj cov nqi khoom siv tau zoo.
Q2: Dab tsi yog qhov yuav tsum tau vuam rau SPA-H?
A (Kev txhawj xeeb ntawm Fabrication):SPA-H muaj qhov zoo tshaj plaws weldability, tab sis cov txheej txheem yuav tsum tsis txhob ua kom yooj yim. Peb pom zoo kom sivqis-hydrogen electrodes (piv txwv li, E5015-G)los yog Corten- cov xov hlau tshwj xeeb uas muaj Cu thiab Ni.
Tseem ceeb: Ua ntej vuam, xeb thiab roj stains ntawm qhov zawj yuav tsum tau muab tshem tawm. Tom qab vuam, ntxuav lub slag raws sij hawm kom tsis txhob vuam tawg. Cov cua kub ntau dhau thaum lub sijhawm ua haujlwm yuav tsum zam kom tsis txhob kub hnyiab ntawm cov ntsiab lus alloying.
Q3: Puas yog SPA-H zoo ib yam li Corten A?
A (Kev txhawj xeeb ntawm tus qauv):Yog, nyob rau hauv lub tswv yim engineering. Corten A yog ib lub cim lag luam (thawj los ntawm Asmeskas), thaum SPA-H yog tus qauv kev lag luam Japanese (JIS). Ob leeg muaj cov ntsiab lus phosphorus siab (P: 0.070 ~ 0.150%), uas ua rau lawv zoo meej rau kev ua kom zoo nkauj, ntom xeb txheej. SPA-H raug suav hais tias yog tus nqi tshaj plaws- zoo sib npaug rau Corten A hauv khw Esxias.
Q4: Koj ntim cov hlau li cas los tiv thaiv xeb liab thaum lub sij hawm thauj khoom hiav txwv?
A (Kev txhawj xeeb txog kev thauj mus los):Txawm hais tias SPA-H yog tsim los xeb tawm sab nraum zoov, xeb liab ntxov ntxov thaum lub caij hla hiav txwv tuaj yeem ua rau mob taub hau loj rau koj lub laser txiav thiab vuam tshuab. Peb muabhwm seaworthy export packing. Cov coils los yog daim hlau yog nruj nreem qhwv nrog cov ntawv tsis muaj dej tsis muaj dej kraft thiab yas zaj duab xis, tom qab ntawd muab khi rau ntawm cov pallets ruaj khov kom cais lawv tawm ntawm cov huab cua ntub dej hiav txwv.
4. Xav tau kev cai SPA-H Fabrication?
Tsis txhob yuav cov khoom nyoos xwb. NtawmGNEE STEEL, peb muab ib qho -tso tseg ua rau SPA-H weathering steel, nrog rau slitting, precision CNC laser txiav (hollow carving), dabtsi yog khoov, thiab ceev nto rusting kev kho mob.
