Cov txheej txheem txias- dov hloov kho cov khoom ntawm SPA-H weathering steel los ntawmtxias- ua haujlwm cov khoom ntawm chav tsev kub(raws li kub dov thiab annealing), uas txhim kho txhua yam muaj zog thiab nto zoo thaum hloov ductility, dimensional precision, thiab patina tsim cov yam ntxwv -tag nrho thaum khaws cia cov tub ntxhais huab cua corrosion kuj ntawm SPA-H.
Cov teebmeem tseem ceeb ntawm Cold Rolling ntawm SPA-H Weathering Steel Properties
● Txhim kho Mechanical Strength & Hardness
Txias dov qhia txog yas deformation thiab ua hauj lwm hardening rau cov hlau, nce nwsyield zogthiabtensile zog(los ntawm kwv yees li 20–30% piv rau kub- dov SPA-H) thiab nce nws cov hardness (piv txwv li, Brinell hardness). Qhov no ua rau txias -rolled SPA-H ntau resistant rau tej yam me me thiab deformation, haum rau precision Cheebtsam uas yuav tsum tau structural rigidity nyob rau hauv nyias gauges.
● Txo Ductility & Formability
Kev ua hauj lwm hardening los ntawm txias dov ho txo cov hlau ductility thiab elongation thaum so. Tsis zoo li kub -rolled SPA-H (uas khoov thiab nkhaus tau yooj yim), txias -rolled SPA-H yog qhov ua rau tawg lossis tawg thaum raugntse khoov, sib sib zog nqus nkhaus, los yog complex 3D sib sau. Nws tsuas yog tsim nyog rau qhov chaw tiaj tus lossis me me, maj mam khoov (loj radii).
●Superior Surface Finish & Dimensional Precision
Txias dov smooths cov hlau qhov chaw los ntawm kev tshem tawm cov nplai zeb ntxhib tsim thaum kub dov, ua rau muaj kev kub ntxhov.low-roughness, matte- du tiav(Ra Tsawg dua lossis sib npaug li 1.6 μm). Cov txheej txheem kuj nruj me ntsis kam rau ua (thickness, flatness, thiab ntev / dav) kom meej meej, tseem ceeb heev rau cov ntawv thov kom raug haum nrog lwm yam khoom (xws li, industrial enclosures, kos npe panels).
●Slower & Tsawg Uniform Patina Tsim
Qhov saum npoo du ntawm qhov txias -rolled SPA-H tshem tawm lub ntuj roughness thiab zeb nplai uas ua kom patina txoj kev loj hlob hauv kub- dov SPA-H. Qhov no ncua sij hawm tsim cov kev tiv thaiv reddish -xim av corten patina thiab tuaj yeem ua raupatchy, uneven rustingyog tias tsis kho. Rau patina-raws li cov ntawv thov (xws li, cov khoom siv kho kom zoo nkauj), txias -rolled SPA-H yuav tsum tau npaj ntxiv rau saum npoo (xws li, sandblasting) los tsim kev ntxhib los mos thiab ua rau oxidation tsis zoo.
●Preserved Corrosion Resistance
Qhov tseem ceeb, cov txheej txheem txias - dov tsis hloov cov tshuaj muaj pes tsawg leeg ntawm SPA-H (uas muaj Cu, Cr, P rau huab cua tsis kam). Yog li, txias-kho SPA-H khaws cia zoo ib yamatmospheric corrosion kujraws li kub-rolled SPA-H- ib zaug ib daim ntawv patina ruaj khov (nrog rau kev kho kom zoo), nws muab kev tiv thaiv sib npaug ntawm cov xeb hauv nroog, nyob deb nroog, thiab me me ntug dej hiav txwv ib puag ncig.
