SPA-H hlau
I. SPA-H steel yog dab tsi
SPA-H steel yog ib hom huab cua-resistant steel. Nws yog cov hlau uas tsis tshua muaj zog siab nrog cov khoom tseem ceeb ntawm hlau, carbon, silicon, manganese, phosphorus thiab sulfur, uas muaj tooj liab, chromium, npib tsib xee thiab lwm yam alloying ntsiab. SPA-H steel muaj cov huab cua zoo heev thiab tuaj yeem siv rau hauv qhov chaw ntev ntev yam tsis muaj kev xeb thiab tsis tas yuav muaj kev tiv thaiv corrosion. Nws kuj muaj qhov zoo weldability, workability thiab qaug zog tsis kam, thiab yog dav siv nyob rau hauv kev tsim kho, txuas hniav, tsheb, ntim, railroads thiab lwm yam teb.
Qhov thib ob, cov yam ntxwv ntawm SPA-H steel
Cov yam ntxwv tseem ceeb ntawm SPA-H steel yog raws li hauv qab no:
1. Cov huab cua tsis zoo: SPA-H steel muaj cov huab cua zoo heev thiab tuaj yeem siv rau hauv cov huab cua ntev ntev yam tsis muaj corrosion thiab tsis tas yuav muaj kev tiv thaiv corrosion.
2. Lub zog siab: SPA-H steel muaj lub zog siab thiab tensile lub zog, uas tuaj yeem ua tau raws li ntau yam kev xav tau ntawm lub sijhawm.
3. Zoo formability: SPA-H steel yog ib qho yooj yim rau kev ua tiav rau hauv ntau yam duab thiab ntau thiab tsawg ntawm cov tswv cuab, uas muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm ntau yam complex qauv.
4. Kev ua haujlwm vuam zoo: SPA-H hlau tuaj yeem txuas nrog ntau txoj kev vuam, nrog kev ua haujlwm zoo ntawm vuam seam, thiab nws tsis yooj yim rau kev tawg thiab deformation tom qab vuam.
5. Kev zoo nkauj zoo nkauj: SPA-H hlau yuav tsim ib txheej oxide txheej rau ntawm qhov chaw, nrog rau kev ntxhib los mos thiab xim, uas tuaj yeem siv los ua cov khoom siv kho kom zoo nkauj.
III. Parameters ntawm SPA-H steel
Lub ntsiab tshuaj muaj pes tsawg leeg ntawm SPA-H hlau

| 490-610MPa | 355MPa ua | 22 feem pua | HB269 Max |
Plaub, daim ntawv thov ntau yam ntawm SPA-H steel
SPA-H steel yog dav siv nyob rau hauv cov nram qab no vim nws zoo heev huab cua tsis kam thiab siab zog: 1. Siv teb: SPA-H steel yuav siv tau raws li zoo nkauj thiab structural ntaub ntawv nyob rau hauv lub teb ntawm lub tsev facades, ru tsev, qhov rooj thiab qhov rais, landscaping, thiab lwm yam. 2. Railway thiab txoj kev loj choj: SPA-H steel yuav siv tau nyob rau hauv kev tsim kho thiab kev loj hlob ntawm txoj kev tsheb ciav hlau. 3. Kev tsim tsheb: SPA-H hlau tuaj yeem siv rau hauv kev tsim cov tsheb thauj khoom, ntim, tsheb thauj khoom, thiab lwm yam. 4. Kev tsim nkoj: SPA-H steel tuaj yeem siv rau kev tsim nkoj, xws li lub nkoj, lub nkoj, thiab lwm yam.
V. Tej teeb meem ntawm SPA-H steel
SPA-H steel tej zaum yuav muaj cov teeb meem hauv qab no hauv cov txheej txheem ntawm kev siv: 1. Cov teeb meem corrosion ntawm qhov chaw: SPA-H steel yuav tsim ib txheej oxide txheej rau ntawm qhov chaw, tab sis yog tias cov oxide txheej tsis sib npaug los yog khawb, thiab lwm yam, nws yuav ua rau lub zos corrosion. 2. Welding teeb meem: SPA-H hlau tsis zoo vuam kev ua tau zoo thiab yuav tsum tau xaiv cov txheej txheem vuam tsim nyog thiab cov khoom siv vuam. 3. Kev tsim cov teeb meem: SPA H steel yog qhov nyuaj rau kev tsim khoom thiab yuav tsum muaj cov txheej txheem tsim khoom tshwj xeeb thiab khoom siv.
