A588GrB Weathering Steel

A588GrB yog ib qho atmospheric corrosion resistant steel raws li ASTM cov qauv, tseem hu ua weathering steel. Nws yog ib yam ntawm cov hlau tsis tshua muaj hlau ua los ntawm kev ntxiv qee yam ntawm cov hlau alloying hauv cov hlau zoo tib yam, cov khoom tseem ceeb tau muab faib ua Cu, P, Cr, Ni thiab lwm yam, thiab cov yam ntxwv ntawm huab cua steel muaj peev xwm tiv taus corrosion hauv qab. ntuj atmospheric tej yam kev mob. Vim lub enrichment ntawm Cu, P thiab lwm yam kab nyob rau hauv lub steel nto, ib tug ntom thiab heev nplaum tiv thaiv zaj duab xis yog tsim los tiv thaiv ntxiv corrosion ntawm lub hauv paus hlau.
Piv nrog cov pa roj carbon zoo tib yam, A588GrB series weathering steel muaj qhov zoo dua corrosion nyob rau hauv cov huab cua. Piv nrog rau cov hlau tsis muaj steel, cov hlau tsis muaj zog tsuas muaj cov ntsiab lus alloying, xws li P, Cu, Cr, Mo, Nb, V, T, thiab lwm yam, thiab tag nrho cov hlau alloying nyiaj tsuas yog ob peb feem pua, es tsis yog kaum feem pua ​​​​ntawm stainless hlau. steel, yog li tus nqi kuj tsawg. Nws yog ib qho ntawm cov qib steel qib nyob rau pem hauv ntej ntawm lub ntiaj teb super steel technology.
