ASTM A572 Steel Lub kaum sab xis Bar
Lub kaum sab xis Steel Beam Product Description
ASTM A572 lub kaum sab xis steel yog lwm lub zog siab qis alloy (HSLA) niobium vanadium seem hlau. Vim yog qhov me me ntawm niobium vanadium alloying caij, kub dov A572 steel hlau lub kaum sab xis muaj cov khoom zoo dua li cov hlau A36 steel hlau kaum.
A572 structural steel lub kaum sab xis muaj lub zog ntau dua, xws li lub zog tawm los thiab lub zog tensile, dua li A36 cov qauv steel lub kaum sab xis, ntxiv rau, nws yooj yim rau vuam, daim ntawv thiab txheej txheem.
A572 kub dov lub kaum sab xis muaj lub zog siab rau qhov hnyav piv thiab yog li muaj ntau yam kev siv. Vim tias nws tsis muaj tooj liab (uas pab tiv thaiv corrosion), A572 cov qauv steel hlau feem ntau yog kub-dip galvanized lossis pleev xim ua ntej.
