A109 Txias Rolled Hlau

INTRODUCTION TO ROLLED STEEL A109

Cold rolled steel yog cov hlau tsis tshua muaj carbon uas ua tiav ntawm chav tsev kub. Vim nws cov txheej txheem, cov ntawv txias-kuav los tiag steel feem ntau ruaj dua kub-kuav los tiag thiab muaj ib tug zoo-zoo tag, ua rau nws ib tug hwm hlau rau daim ntaub ntawv xws li tsheb thiab cov khoom siv hauv tsev, qhov ua tiav nws yog ib qho tseem ceeb ntawm ob daim ntawv thiab muaj nuj nqi.

A109 Txias Rolled Steel Khoom Specifications

GNEE steel stocks ASTM A109 txias dov steel sawb nyob rau hauv qhov kub thiab txias los ntawm 1 lb (tag nrho nyuaj) mus rau 5 lb (tag nrho cov mos). ASTM A109 sawb hlau muaj cov tuab tuab dua li ASTM A1008 steel. Nws yog castable heev, nyob ntawm qhov kub thiab txias, thiab muaj txiaj ntsig zoo rau ntau yam kev siv.
