Dab tsi yog qhov seem tsis kam kam rau s355j0wp huab cua dav hlau?

TusQhov seem ntevrauS355J0WP Weathering Hlaunyob ntawm nws daim ntawv foos (phaj, ntawv, bar, cov qauv sib txawv) thiab yog tswj hwm los ntawmCov Qauv European (En)Cov. Hauv qab no yog cov qauv ua siab ntev rau cov hom sib txawv ntawm S355J0WP:

1. Hlau Daim Hlau & Cov Ntawv Qhia (EN 10029)

Thickness kam rau:

RauThickness tsawg dua los yog sib npaug rau 80 hli, Txheem kev thev xim thov (piv txwv li, ± 0.3 hli rau 10 hli phaj).

RauThickness> 80 mm, Wider toresances (± 1-2% ntawm nominal tuab).

Dav / Ntev Dag:

Dav:10 hli (tus qauv), ± 5 hli (siab dua).

Ntev:± 0-50 hli (nyob ntawm cov txheej txheem txiav).

2. Kub-Rolled Cov Qauv Txheej Txheem (EN 10034)

I-Beams, H-Beams, Raws, Cov Kaum:

Qhov siab / dav:2-4 hli (rau cov profiles txog 400 hli).

Flange tuab:± 0.5-1.5 hli.

Ncaj ncees:Tus zuag0.15% ntawm qhov ntev(piv txwv li, 3 mm sib txawv ib 2 m).

3. Round & Ca Ca (EN 10060, thiab 10058/10059)

Txoj kab uas hla / thickness kam rau:

Round Round (EN 10060):± 0.5-1.5 hli (rau 10-50 hli inch).

Cov kab tuav (thiab 10058):± 0.3-0.8 hli (tuab), ± 1-3 hli (dav).

4. Kev zam rau huab cua hlau vs. tus qauv hlau

Tib yam li cov qib tsis yog huab cua(piv txwv li, s355jr) txij li kev thev taus yog rawsDaim ntawv foos, tsis yog khoom hom.

Cov kev pab tshwj xeeb (piv txwv li, thiab 10051 rau Sawb / Chev)tej zaum yuav thov rau cov khoom txias.

5. Nto & Edgle Doles

Deg roughness (en 10163):

Chav kawm a (du) rau chav kawm d (raws li-dov).

Ntug dej:

Zeb npoo (zam lub hnub nyoog tsis txaus ntseeg) vs. sheared / machined npoo (nruj tev taus).
