Khoom Description
A36 steel zoo ib yam li Q235B steel, nws yog ib Q235b sib npaug steel qauv, lwm tus yog SS400. Thaum qhov sib txawv ntawm A36 thiab Q235B yog raws li hauv qab no:
Cov ntsiab lus sib txawv (A36=250MPa, Q235B=235MPa);
Sib txawv Tensile Strength (A36=400-550MPa, Q235B=375-500MPa);
Cov ntsiab lus sib txawv: (A36: C yog sib npaug los yog tsawg dua 0.25%, Si tsawg dua lossis sib npaug rau 0.4%, P < 0.{{ 7}}4%, s tsawg dua lossis sib npaug rau 0.05%; Q235B:C{{10}}.12-0.2%, Si yog tsawg dua los yog sib npaug rau 0.3, P < 0.045%, s yog sib npaug los yog tsawg dua 0.045%).Q235 manganese cov ntsiab lus ntawm cov kev xav tau (Mn=030-0.70%) A36 manganese cov ntsiab lus tsis tas yuav tsum muaj.

Channel steel yog ib tug ntev strip ntawm steel nrog ib tug zawj-zoo li tus ntoo khaub lig-section. Nws yog cov khoom siv carbon steel siv hauv kev tsim kho thiab tshuab. Nws yog ib qho profile steel nrog txoj kev hla ntu thiab muaj qhov zawj-shaped cross-section. Channel steel yog tsuas yog siv nyob rau hauv lub tsev tsim, ntaub thaiv phab ntsa engineering, mechanical khoom thiab tsheb manufacturing.
Cov lus qhia tshwj xeeb ntawm channel steel feem ntau qhia los ntawm qhov siab (h), ceg dav (b), lub duav tuab (d) thiab lwm qhov ntev. Cov specifications ntawm domestic channel steel ntau ntawm 5 mus rau 40, uas yog, qhov sib thooj qhov siab yog 5 mus rau 40cm.
Nyob rau tib qhov siab, lub teeb channel steel muaj cov ceg nqaim, lub duav nyias nyias thiab sib zog dua li cov hlau zoo tib yam. No. 18 txog 40 yog cov hlau loj loj, thiab No. 5 txog 16 yog cov hlau nruab nrab. Imported channel steel yog cim nrog qhov tseeb specifications, qhov ntev thiab lwm yam qauv. Cov kev txiav txim ntshuam thiab xa tawm ntawm channel steel feem ntau yog ua raws li cov lus qhia tshwj xeeb uas yuav tsum tau siv tom qab txiav txim siab cov pa roj carbon steel (lossis qis alloy steel) qib steel. Sib nrug los ntawm cov lej tshwj xeeb, channel steel tsis muaj qhov tshwj xeeb muaj pes tsawg leeg thiab kev ua tau zoo series.
Kev xa tawm ntev ntawm cov hlau channel tau muab faib ua ob hom: qhov ntev ntev thiab ob npaug ntev, thiab tus nqi kam rau ua tau teev nyob rau hauv cov qauv sib xws. Qhov ntev xaiv ntau yam ntawm domestic channel steel yog muab faib ua peb hom raws li txawv specifications: 5-12m, 5-19m, thiab 6-19m. Qhov ntev xaiv ntau yam ntawm cov khoom siv channel steel feem ntau yog 6-15m.
