1.Dab tsi yog qee hom hlau uas ua tau raws li cov qauv hauv Suav teb?
Q195, Q215, Q235
Ordinary carbon structural steel. Q235 yog qhov siv dav tshaj plaws vim nws qhov kev ua tau zoo tag nrho.
2.Dab tsi yog qee yam khoom siv hlau raws li cov qauv Japanese?
SPCC, SPCD, SPCE
Cov no sawv cev rau qhov dav dav -lub hom phiaj, stamping, thiab sib sib zog nqus-kos duab txias-rolled carbon steel los xij, feem. Cov qib siab qhia tau zoo dua elongation thiab stamping kev ua tau zoo.
3.Dab tsi yog qee cov khoom siv hlau feem ntau raws li European / German qauv?
DC01, DC03, DC04
Kev siv dav hauv Tebchaws Europe, tus lej ntau dua (xws li DC04 / ST14) qhia txog cov khoom siv softer thiab zoo dua sib sib zog nqus- kos duab.
4.Yuav ua li cas txheeb xyuas cov ntaub ntawv raw raws li lawv cov tshuaj muaj pes tsawg leeg?
SPCC / DC01: Haum rau kev stamping thiab sib sau
SPCD / DC03: Haum rau cov txheej txheem stamping nyuaj, nrog cov ntsiab lus qis dua.
SPCE / DC04: Haum rau kev sib sib zog nqus nqus, cov ntsiab lus carbon tsawg, siab elongation.
5.Vim li cas ho kub - dov coils siv los ua raw khoom?
Dimensional Transition: Kub- dov coils feem ntau yog tuab dua (piv txwv li, 1.5-6mm lossis ntau dua). Txias dov (dov ntawm chav tsev kub) tuaj yeem txo lawv cov tuab mus rau 0.2-4mm, ua tiav cov tuab tuab dua.
Txhim kho kev ua tau zoo: Kub- dov coils muaj hlau oxide nplai ntawm lawv qhov chaw thiab lawv cov khoom tsis sib xws. Txias dov thiab tom qab annealing kev kho mob tuaj yeem tsim cov khoom txias- dov nrog cov khoom tiav, siab qhov tseeb, thiab cov khoom siv zoo.
