Dab tsi yog cov khoom ntawmCr340la + zSteel Chev?
Cov khoom siv hauv paus ntawm CR340LA + Z Galvanized Steel Chev yog txias-alloy) Galvanized chev, thiab saum npoo yog kub-dip galvanized (z)
Kev sib xyaw cov yam ntxwv:
Cov pa roj carbon (C tsawg dua lossis sib npaug rau 0. 12%): Ua kom ntseeg tau tias Weldability thiab Formability.
Microalloying ntsiab (xws li NB, V): txhim kho lub zog los ntawm cov hmoov nplej nplua zog thiab los nag.
Tsawg phosphorus, qis leej faj (p, s tsawg dua los yog sib npaug rau 0. 025%): txhim kho stamping kev ua tau zoo thiab tawv

Hom txheej txheej:
GI (kub-dip galvanized): ntshiab zinc txheej, ci dawb nto, zoo corrosion tsis kam.
GA (Galvannealed): zinc-iron alloy coating (Fe-Zn alloy), dark gray color, better weldability.
Txheej hnyav: nquag ob tog txheej thib 2\/60 g \/ m² (Z60), tuaj yeem kho tau raws li kev xav tau

CR340LA + Z tus hlau siv rau?
CR340LA + Z Galvanized Steel Chev yog ib qho "ua lag luam ntawm txhua lub lag luam" uas muab cov khoom siv dag zog, corrosion tsis kam thiab nqi-ua hauj lwm zoo. Nws yog siv rau:
Lub tsheb kev nyab xeeb (yuav tsum tau tsim qauv kev tsim)
Pom zoo qauv: CR340LA + ZF (Zinc-Hlau Alloy Txheej)
Yog vim li cas: Tsawg dua vuam pa taws, ntau haum rau kev siv hlau tshuab tshuab hluav taws xob vuam ntau lawm kab
Cov Khoom Siv Hauv Tsev (yuav tsum tau ua tau zoo + xeb kev tiv thaiv)
Pom zoo qauv: CR340LA + Z (du nto)
Vim li cas: nto ra tsawg dua los yog sib npaug rau 0. 8μm, tuaj yeem sib tsoo, tshem tawm cov txheej txheem sib tsoo
Lub tsev load-cov kabmob qauv (yuav tsum tau lub neej ntev + siab thauj)
Pom zoo qauv: CR340LA + Z120 (txheej tuab)
Vim li cas: C3 \/ C4 corrosion ib puag ncig (xws li cov nroj tsuag tshuaj) yuav tsum muaj qib siab dua ntawm corrosion tsis kam
Yuav muaj CR340LA + Z Cov Hlau Hloov Galvanized Steel (DX51D + Z)?
Yog lawm, tab sis cov kev xav tau yuav tsum tau ntsuas - CR340LA + Z muaj zog thiab haum rau load-cov kabmob hauv; Steel zoo tib yam hlau yog qhov tsim nyog rau cov qauv dav dav.
Lub zinc txheej puas cuam tshuam vuam?
GA (Zinc-Hlau Alloy) Txheej muaj tau zoo dua weldability tshaj gi (ntshiab zinc), tab sis cov kev siv tam sim no yuav tsum tau muab rau hauv vuam (zinc vapor yog qhov tsis zoo)
