Hoobkas Lag Luam Wholesale Tensile Zog ASTM Sib Npaug Lub kaum sab xis Steel Nqe Zoo 50 * 5 60 * 5 63 * 6 Lub kaum sab xis me me

Cov ces kaum hlau kub dovyog cov khoom siv ua vaj tse uas siv tau ntau yam thiab siv dav hauv kev tsim kho thiab kev siv hauv kev lag luam. Nov yog qee cov ntsiab lus tseem ceeb txog cov ces kaum hlau kub dov:

Cov Txheej Txheem Tsim Khoom: Cov hlau kub dov lub kaum sab xis yog tsim los ntawm kev ua kom sov cov hlau billet lossis ingot rau qhov kub siab thiab dhau nws los ntawm cov menyuam kom nws zoo li lub kaum sab xis xav tau.

Cov Khoom Siv Sib xyaw: Cov ces kaum no feem ntau yog ua los ntawm cov hlau carbon, nrog rau cov khoom sib xyaw tshwj xeeb raws li cov khoom xav tau thiab cov kev xav tau ntawm lub zog.

Cov Khoom Siv Hauv Tsev: Cov kaum hlau kub dov muaj lub kaum sab xis 90-degree nrog cov ceg sib npaug lossis tsis sib npaug. Lawv siv dav los muab kev txhawb nqa, kev txhawb nqa, thiab lub moj khaum hauv ntau yam kev siv.

Qhov Loj TxheemCov ces kaum hlau kub dov muaj ntau qhov loj me, nrog rau qhov loj me rau cov ceg kaum thiab tuab. Cov qhov loj me no tau teev tseg los ntawm cov qauv kev lag luam xws li ASTM (American Society for Testing and Materials) lossis lwm cov qauv hauv cheeb tsam.

Qhov Chaw Tiav: Qhov chaw ntawm cov hlau kub dov lub kaum sab xis muaj qhov chaw scaly vim yog cov txheej txheem txias tom qab dov. Cov qauv nto no yog ib txwm muaj rau cov hlau kub dov thiab tsis cuam tshuam rau kev ua tiav ntawm cov khoom siv.
