ASTM A588GrA GrC huab cua steel phaj
Corrosion Resisting Cov Khoom Siv Hlau Cov Khoom Piav Qhia
A588 GrA corten cov ntaub ntawv yog rau lub zog siab uas tsis tshua muaj alloy qauv hlau nrog qhov tsawg kawg nkaus taw tes ntawm 345Mpa thiab lub thickness ntawm 100 hli.
A588 GrC corten hlau ntawv yog lub zog siab qis alloy cov qauv hlau tshwj xeeb nrog kev txhim kho atmospheric corrosion tsis kam rau cov qauv hlau zoo li cov ces kaum, raws thiab kab teeb, nrog rau cov hlau phaj thiab rebars.
A588 GrA corten daim ntawv thiab A588 GrC atmospheric corrosion resistant steel yog siv rau ntau hom welded, bolted thiab riveted lug xws li steel ncej, txuas hniav, tso tsheb hlau luam thiab ntim, tso tshuab, tsheb thiab khoom siv.
