JIS G3125 SPA -H Corten Steel yog dab tsi?
SPA-H yog qhov qis- alloy, siab-lub zog atmospheric corrosion-cov hlau tsis muaj zog uas txhais los ntawm Japanese Industrial Standard (JIS G3125). Nws yog cov khoom siv ntsuas thoob ntiaj teb raushipping thawv manufacturing. Tsis zoo li cov qauv carbon steel, SPA-H muaj cov ntsiab lus alloying tshwj xeeb uas tsim muaj kev tiv thaiv kev tiv thaiv oxygen thiab noo noo, ua rau nws zoo tagnrho rau hnyav marine thiab kev lag luam ib puag ncig.
vim li cas thiaj xaiv promisteel
Peb tab tom nrhiav kev sib koom tes los nthuav peb txoj kev lag luam.
Precision Slitting: Tshem tawm cov kab ntau lawm
Peb daws qhov mob taub hau ntawm qhov ntev ntev. Promisteel muab customized thickness (2.0-35.0mm) thiab dav (600-3000mm) nrog nruj kam rau ua. Peb precision slitting kom cov coils pub smoothly rau hauv koj automated stamping kab yam tsis muaj jamming los yog pov tseg.
Ntawv pov thawj Alloy Cov ntsiab lus: 100% JIS G3125 Ua raws
Kev txhawj xeeb txog fake "corten" steel? Peb nruj me ntsis ua raws li tus qauv JIS G3125, kom ntseeg tau qhov tseeb feem ntawm tooj liab (0.25-0.60%), Chromium (0.30-1.25%), thiab Nickel (tsawg dua lossis sib npaug li 0.65%). Txhua lub kauj tuaj nrog daim ntawv pov thawj Mill Test (MTC) thiab txhawb kev soj ntsuam thib peb (xws li SGS).
Superior Formability: Zero Cracking Thaum Sib Nqus Kos Duab
Thawv panels yuav tsum tau complex corrugation. Peb SPA-H coils feature tswj lub zog muaj zog (Ntau dua lossis sib npaug ntawm 345MPa rau Tsawg dua lossis sib npaug li 6 hli) thiab zoo heev Elongation (Ntau dua lossis sib npaug li 22%). Qhov no ua kom cov khoom muaj peev xwm tiv taus dabtsi yog khoov (lub vojvoog 0.5t) thiab cov txheej txheem sib sib zog nqus tsis tau tawg lossis deforming.
Marine- Qib Durability: 2-8x Lifespan ntawm Carbon Steel
Tsis tu ncua lub thawv ntim khoom. Ua tsaug rau cov txheej txheej oxide tuab tsim los ntawm Cu, Cr, thiab Ni, peb cov SPA-H steel muaj 2 txog 8 npaug ntawm huab cua corrosion zoo dua li cov pa roj carbon zoo tib yam. Nws yog tsim los tshwj xeeb kom tiv taus siab - ntsev marine pos huab thiab huab cua kub hloov pauv.
Weldability Guarantee: Tsis muaj "Weak Links" hauv Cov Qauv
Cov qauv kev ncaj ncees nyob ntawm qhov zoo welds. Peb nruj me ntsis tswj impurities xws li Phosphorus (tsawg dua los yog sib npaug rau 0.040%) thiab Sulfur (tsawg dua los yog sib npaug rau 0.030%). Qhov no ua kom peb cov SPA-H steel tswj cov qauv kev ruaj ntseg thaum lub sij hawm vuam, tiv thaiv kev tawg ntawm cov pob txha hauv lub thawv ces kaum thiab cov ncej.
Nqi Efficiency: Tsawg Lifecycle Maintenance
Txo koj Tus Nqi Tag Nrho Cov Tswv Cuab (TCO). Thaum pheej yig dua pem hauv ntej, carbon steel yuav tsum tau repainting tas li. SPA-H txo qhov kev xav tau ntawm kev saib xyuas ntau zaus thiab rov ua dua vim nws tus kheej- kho xeb txheej, txo cov nqi ua haujlwm ntau dua lub ntim khoom lub neej.

Muaj peev xwm ua tau
- Khoov:Rau thickness tsawg dua los yog sib npaug rau 6 hli, qhov tsawg kawg nkaus khoov vojvoog yog 0.5 npaug ntawm cov thickness, kom ntseeg tau meej kev tsim ntawm corrugated panels.
- Vuam:Cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.12%) thiab tswj cov impurities tso cai rau siab - vuam zoo yam tsis muaj qhov tshwj xeeb ua ntej- cua sov hauv feem ntau cov ntawv thov ntim.
- Slitting:Peb muab precision slitting rau coils kom tau raws li koj qhov kev dav dav, xws li ntawm 600mm txog 3000mm.
Daim ntawv thov
Thaum SPA-H yog tus qauv kub raumarine shipping ntim, nws durability ua rau nws muaj ntau yam kev xaiv rau:
- Land Logistics:Railway vans thiab tsheb thauj khoom.
- Khoom siv:Anti-corrosion structural qhov chaw nyob rau hauv sulfur- ib puag ncig nplua nuj.
- Chaw nres nkoj Infrastructure:Cov cuab yeej raug rau siab ntsev tsuag.
