Kub - dipped galvanized steel chev ittm A792
ASTM A792 yog cov khoom siv Asmeskas cov lus qhia tshwj xeeb. Cov ntawv hlau no tsim tawm los ntawm kev raus ib daim hlau nyias nyias rau hauv Molten Zinc da dej uas adheres ib qho ntawm cov txheej txheem galvanizing txuas ntxiv.
Kub - dip galvanized steel chev it792 yog siv dav hauv ntau yam kev tsim kho hauv kev tsim kho hauv ntau yam hauv tsev, cov khoom siv hauv tsev, cov thawv tsim thiab lwm thaj teb. Nws cov nplaum zoo ntawm cov xim pleev xim thiab weldability ua rau nws dav siv nyob rau hauv ntau yam kev lag luam.
Kub - dipped galvanized steel chev - dip galvanized steel chev ua raws li Astm A792 tus qauv.
ASTM A792 yog tus qauv tsim los ntawm Asmeskas haiv neeg rau kev sim thiab cov khoom siv (ASTM).

Lub ASTM A792 tus qauv sib cais ua cov txheej txheem rau qib rau 6 qib siab, uas yog AZ150, AZ120, AZ120, AZ13 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100 thiab AZ100.
Cov txheej txheem zoo ntawm cov txheej nyob ntawm seb nws thickness, hnyav ntub dej kuaj thiab hluav taws xob lub kaum sab xis kuaj.
Tsis tas li ntawd, tus qauv kuj tseem ua rau cov khoom siv me me ntawm cov txheej txheem steel, kom muaj zog los yog thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm cov hnoos qeev mus kuaj thiab kuaj, ASTM A792 qhia txog txoj kev ntsuas thiab qhia cov qauv tshuaj rau cov khoom siv sib xyaw ua ke. Cov qauv kev ntsuas no suav nrog tshuaj ntsuam xyuas tshuaj lom neeg, ntsuas hluav taws xob, tshuab ntxhua xov, Tensile kuaj, puas yog kuaj, thiab lwm yam.
