DC01 kauj cov yam ntxwv txhua yam
Cov cuab yeej siv cov tshuab ntawm DC01 txias-dov chev (tsis-galvanized) feem ntau nyob rau hauv lub European txheem thiab kev ntsuas cov neeg muaj npe hauv qab no:
1. Cov cuab yeej ua haujlwm (en 10130)
Kev ua tau zoo parameter tseev kom muaj (ntev hnoos qeev) kev sim
Tensile lub zog (RM) 270-410 mpa en iso 6892-1
Yield zog (RP0.2) ntau dua los yog sib npaug rau 140 MPa (feem ntau 160-280 MPa) en ISO 6892-1
Elongation (a80mm) ntau dua lossis sib npaug ntawm 28% (rau thickness tsawg dua los yog sib npaug rau 2 hli) en ISO 6892-1
Hardness (HRB) 40-75 (nyob ntawm anealing mob) en ISO 6506
2. Cov ntawv tseem ceeb
Cov taw qhia kev taw qhia: cov khoom siv neeg kho tshuab feem ntau yog ntsuas hauv cov kev coj ua (kev coj ua ntev); Transverse cov khoom yuav yog qhov qis me ntsis.
Yuav ua li cas Thickness cuam tshuam kev ua tau zoo?
Nrog thinner thickness, tawm lub zog thiab elongation zog yuav hloov me ntsis (piv txwv li, rau thicknesses<0.5mm, elongation may be slightly lower).
Annealed mob: DC01 feem ntau muab rau hauv anealed (mos) mob kom ntseeg tau tias zoo muaj formability.
3. Qhov sib txawv ntawm galvanized chev (dc 01+ z)
Rau galvanized coils (xws li DC 01+ h lossis dx51d), cov khoom siv mechanies yog ib yam li cov khoom siv hauv paus, tab sis thov nco ntsoov:
Cov txheej txheem galvanizing (kub-dip / electroplating) muaj tsawg heev rau kev ua tau zoo, tab sis tuaj yeem nce nrawm dua (cov txheej zinc ntau dua).
The weight of the zinc coating (such as Z60/Z80) does not affect the mechanical properties of the base material.
4. Cov ntaub ntawv thov cov ntaub ntawv
Stamping: Tsawg tawm lub zog zog thiab elongation yog qhov tsim nyog rau cov pawg boldings yooj yim (xws li cov tshuab hluav taws xob yooj yim).
Dabtsi yog khoov: qhov tsawg kawg nkaus khoov radius yog kwv yees li ntawm cov tuab (piv txwv li, 1mm tuab cov khoom tuaj yeem bent rau 1 hli).
5. Ob txoj kev kuaj no yog dab tsi?
Tensile Xeem: Raws li Ero 6892-1, patchimen qhov dav 20 hli, ntsuas cua ntev 80 hli (A80).
Kuaj Hardness: Tog twg los rockwell hardness (HRB) lossis vickers hardness (HV) tuaj yeem xaiv tau.
