S280GD galvanized steel ntawv
S280GD galvanized steel nplooj ntawv thiab daim hlau tsis tshua muaj - carbon hlau uas coated nrog zinc los ntawm cov txheej txheem kub -dip galvanizing los tiv thaiv nws ntawm corrosion. Cov hlau feem ntau yog ua los ntawm hlau, nrog me me ntawm carbon, manganese, thiab silicon los txhim kho nws lub zog thiab formability. Nws muaj lub zog tawm los ntawm 280 MPa, uas ua rau nws haum rau nruab nrab load-cov ntaub ntawv kabmob, raws li EN 10346 tus qauv.
Lub zinc txheej pab tiv thaiv xeb, ua rau S280GD yog ib qho kev xaiv zoo rau ib puag ncig nrog cov dej noo, ntsev, lossis lwm yam corrosive. Nws yog feem ntau siv rau hauv kev tsim kho rau lub ru tsev thiab phab ntsa panels, hauv kev lag luam tsheb rau lub cev panels thiab undercarriages, thiab hauv cov khoom siv xws li tub yees thiab tshuab ntxhua khaub ncaws. Ua tsaug rau nws qhov sib npaug ntawm lub zog thiab kev tiv thaiv corrosion, S280GD ua haujlwm zoo hauv ntau yam kev lag luam.
