09CuPCrNi-A yog huab cua-resistant steel phaj uas muaj qhov sib ntxiv ntawm cov khoom me me xws li Cu, P, Cr, thiab Ni. Cov ntsiab lus no pab tsim cov txheej tuab ntawm cov txheej xeb thiab cov hlau hauv paus, txhim kho cov hlau tsis kam rau atmospheric corrosion. Thoob ntiaj teb, hom hlau no hu ua Corten steel, nrog CorTen-A yog qib sawv cev uas zoo ib yam li Tuam Tshoj tus 09CuPCrNi-A. Feem ntau siv thickness rau 09CuPCrNi-A Corten steel ranges ntawm 1.5 mus rau 50 hli.
05CuPCrNi yog ib hom huab cua-resistant hlau uas muaj xws li tooj liab (Cu), phosphorus (P), chromium (Cr), thiab npib tsib xee (Ni) nyob rau hauv nws cov tshuaj muaj pes tsawg leeg. Nws muaj cov huab cua zoo heev, tiv thaiv corrosion, thiab cov khoom siv kho tshuab. Nws yog feem ntau siv rau hauv kev tsim cov chaw sab nraum zoov thiab cov vaj tsev tsim vaj tsev, xws li canopies, planters, thiab txuas hniav.

Weathering steel muaj atmospheric corrosion kuj 3 mus rau 4 npaug ntawm cov qauv hlau zoo tib yam. Txawm tias siv tsis muaj txheej txheej, nws cov corrosion kuj tuaj yeem kav ntev dua 30 xyoo. Weathering steel yog yooj yim thiab ntau yam, raws li nws tuaj yeem pleev xim lossis siv liab qab, ua kom yooj yim rau cov txheej txheem ntau lawm. Los ntawm kev tshem tawm cov txheej txheem xws li pickling thiab kub-dip galvanizing, nws txo cov nqi tsim khoom. Tsis tas li ntawd, tsis siv cov coatings tiv thaiv cov emission ntawm VOCs (volatile organic compounds), ua rau nws zoo ib puag ncig thiab muaj txiaj ntsig zoo rau kev rov ua dua tshiab. Txij li thaum corrosion kuj ntawm weathering steel cia siab rau nws cov khoom siv tag nrho, nws tsis tshua muaj kev cuam tshuam rau sab nraud xws li khawb thiab dents, tsis zoo li cov hlau tsis tu ncua uas nyob ntawm kev kho deg rau kev tiv thaiv.
09CuPCrNi-A yog ib hom khoom siv huab cua, ntawm ntau cov khoom siv huab cua xws li Q235NH, Q235NHA, Q235NHB, thiab Q235NHC, uas paub zoo hauv Suav teb cov qauv.
Lwm cov huab cua huab cua xws li Q295NH, Q295NHA, Q295NHB, Q295NHC, Q355NHA, Q355NHB, Q355NHC, thiab Q355NHD. Tsis tas li ntawd, muaj cov huab cua huab cua ntau yam ua tau raws li cov qauv European, xws li S355J0W, S355J2W, thiab S355J0WP, nrog rau Asmeskas cov qauv corrosion-resistant steels xws li A709-50 W, A709-50T, A588GrA, A588GrB, thiab CortenB.
Dhau li ntawm huab cua huab cua, peb kuj muab cov hlau tiv thaiv corrosion zoo li ND steel Q345NS thiab 09CrCuSb, nrog rau cov phaj siab, cov hlau tsis tshua muaj hlau, cov hlau tsis muaj steel, nkoj tsim cov phaj, cua ntauwd steel, siab nkoj steel phaj, siab- nce kev tsim kho steel, choj daim hlau, high-carbon steel, thiab alloy structural steel. Peb kuj tuaj yeem tsim cov ntaub ntawv no raws li cov kev cai uas tau teev tseg hauv Asmeskas lossis European cov qauv.
