Zn Txheej Mild Steel Dub Galvanized Lub kaum ntse ntse tsis sib xws
Cov cim ntsuas cov khoom lag luam: cov tshuaj lom neeg muaj pes tsawg leeg ntawm lub kaum sab xis yog c, mn, p, s plaub.Nyob ntawm qib, cov ntsiab lus sib txawv, nrog qhov kwv yees li ntawm C <0.22%, Mn: 0.30-0.65%, P<0.060%, S<0.060%.
1. Kev sim tshuaj.
1) Tensile xeem txoj kev xeem.Feem ntau siv cov qauv xeem yog GB / T228-87, JISZ2201, JISZ2241, ASTMA370, ГОСТ1497, BS18, DIN50145, thiab lwm yam.
2) Bending xeem txoj kev.Feem ntau siv cov qauv xeem yog GB / T232-88, JISZ2204, JISZ2248, ASTME290, ГОСТ14019, DIN50111, thiab lwm yam.
2. Kev ntsuas kev ua tau zoo: cov khoom ntsuas ntsuas kev ua haujlwm ntawm lub kaum sab xis steel feem ntau yog ntsuas tensile thiab khoov ntsuas.Indicators muaj xws li yield point, tensile zog, elongation thiab dabtsi yog khoov cov khoom tsim nyog.
Lub kaum sab xis steel yog dav siv nyob rau hauv ntau lub tsev tsim thiab engineering, xws li cov kab teeb hauv tsev, txuas hniav, lub zog xa hluav taws xob, nqa thiab tsheb thauj mus los machinery, nkoj, industrial furnaces, tshuaj tiv thaiv yees, thawv racks thiab warehouse txee, thiab lwm yam.
Nws yog feem ntau muab faib ua ob pawg: lub kaum sab xis sib npaug thiab tsis sib npaug ntawm lub kaum sab xis, ntawm qhov tsis sib xws ntawm lub kaum sab xis tuaj yeem muab faib ntxiv rau qhov tsis sib npaug ntawm sab sib npaug thiab qhov sib npaug ntawm sab tsis sib npaug.
Cov specifications ntawm lub kaum sab xis steel nrog sab ntev thiab sab thickness ntawm qhov loj ntawm tus sawv cev.Tam sim no, lub kaum sab xis ntawm lub tsev steel specifications rau 2-20, tus naj npawb ntawm centimeters rau tus naj npawb ntawm sab ntev, tib lub kaum sab xis feem ntau muaj 2-7 txawv sab thickness.Cov ces kaum txawv teb chaws raug cim nrog qhov loj me ntawm ob sab thiab sab thickness thiab qhia txog cov qauv tsim nyog.Feem ntau, sab ntev ntawm 12.5cm lossis ntau dua yog lub kaum sab xis loj, ntawm 12.5cm-5cm yog lub kaum sab xis nruab nrab, thiab sab ntev ntawm 5cm lossis tsawg dua yog lub kaum sab xis me.

Equilateral Angle Vector
Qhov kev txiav txim ntawm ntshuam cov steel feem ntau yog raws li cov kev qhia tshwj xeeb uas yuav tsum tau siv, thiab nws tus lej Steel yog qhov sib raug hlau knotted steel tooj.Tsis tas li ntawd lub kaum sab xis steel tsis muaj qhov tshwj xeeb thiab kev ua tau zoo series ntxiv rau tus lej tshwj xeeb.Kev xa khoom ntev ntawm lub kaum sab xis steel yog muab faib ua ob hom kev ruaj khov ntev thiab ob qhov ntev.Qhov ntau ntawm kev xaiv ntev ntev ntawm cov hlau hauv tsev yog 3-9m, 4-12m, 4-19m thiab 6-19m nyob ntawm tus lej specification.Qhov ntev xaiv ntau yam ntawm Nyiv-ua lub kaum sab xis steel yog 6-15m.
Qhov siab ntawm cov kaum sab xis yog xam los ntawm qhov dav ntawm sab ntev ntawm cov kaum sab xis.Nws hais txog cov hlau nrog ib qho angular hla ntu thiab tsis sib npaug ntawm ob sab.Nws yog ib qho ntawm cov ces kaum.Nws sab ntev yog los ntawm 25mm × 16mm mus rau 200mm × l25mm, uas yog dov los ntawm kub dov zeb.
Cov lus qhia dav dav ntawm cov kaum tsis sib xws yog: ∟50 * 32-∟ 200 * 125 Thickness yog 4-18mm.
GB / T2101-2008 (Cov kev cai dav dav rau kev lees txais, ntim, cim thiab ntawv pov thawj zoo ntawm cov hlau seem)
GB / T706-2008 (hloov GB / T9787-88 GB / T9788-88) (loj, duab, hnyav thiab tso cai sib txawv ntawm kub dov equilateral / tsis sib npaug cov ces kaum).
JISG3192-94 (Cov duab, qhov ntev, qhov hnyav thiab lawv qhov sib txawv ntawm qhov kub-kuav los tiag).
DIN 17100-80 (cov qauv zoo rau cov qauv hlau zoo tib yam).
ГОСТ535-88 (cov txheej txheem rau cov pa roj carbon zoo tib yam).
Raws li cov qauv kev qhia saum toj saud, cov ces kaum tau hais los, cov sib tw yuav raug khi, thiab qhov ntev ntawm cov kab ke yuav tsum raws li cov cai.Lub kaum sab xis yog feem ntau xa hauv cov pob liab qab thiab yuav tsum tau tiv thaiv los ntawm ya raws rau kev thauj mus los thiab khaws cia.
