S320GD Galvanized Steel Chev
S320GD Galvanized Steel Chev yog siab -lub zog, kub- dov steel nrog kub-dip galvanized txheej. Nws yog feem ntau tsim los ntawm carbon, manganese, silicon, thiab cov kab ntawm phosphorous thiab sulfur, muab cov machinability zoo thiab formability. Nrog lub zog tawm los ntawm 320 MPa thiab lub zog tensile xws li 400 txog 500 MPa, S320GD yog qhov zoo- haum rau nruab nrab- daim ntawv thov load.
Cov txheej txheem galvanized ntawm cov hlau kauj feem ntau yog tsim los ntawm cov txheej txheem kub -dip galvanizing. Nws thickness nyob ntawm daim ntawv thov tshwj xeeb - tuab dua thiab siab dua - cov txheej txheem zoo muaj kev tiv thaiv corrosion zoo dua. Cov txheej no ua rau muaj kev txhim kho zoo ntawm cov hlau kauj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj cov av noo los yog tshuaj lom neeg, ua rau nws zoo tagnrho rau kev lag luam xws li marine, tshuaj, thiab kev tsim kho. Qee zaum, aluminium-zinc alloy txheej yuav raug siv los txhim kho kev tiv thaiv corrosion.

S320GD Galvanized Steel Chev Mecahmical Properties
| Khoom | Tus nqi |
| Tensile zog (Rm) | 290 - 390 MPa |
| 0.2% Pov Thawj Zog (Rp0.2) | Ntau dua lossis sib npaug li 320 MPa |
| Tsawg kawg Elongation (Lo=80 mm) (A) | Ntau dua lossis sib npaug li 17% |
Nco tseg:
Qhov tsawg kawg nkaus elongation yuav tsum tau sib txawv nrog thickness:
0.5 hli
0.35 hli
t Tsawg dua lossis sib npaug li 0.35 mm: Qhov tsawg kawg nkaus elongation yog txo los ntawm7%piv rau tus nqi teev tseg.
Lub zog tensile ntau rau qib no tuaj yeem sib txawv mus txog140 MPa, nyob ntawm kev ua haujlwm thiab txheej txheej specifications.

FAQ:
Puas yog Z275 txaus rau kev siv sab nraum zoov?
Yog lawm. Z275 haum rau feem ntau qhov chaw sab nraum zoov, suav nrog hauv nroog thiab nyob deb nroog. Rau cov ntug hiav txwv dej los yog ib puag ncig corrosive heev, zinc coatings yuav raug pom zoo.
Qhov txawv ntawm S320GD thiab qis dua -qib galvanized steel yog dab tsi?
S320GD muaj lub zog muaj zog ntau dua thiab ua haujlwm zoo dua -cov kabmob muaj peev xwm thaum tswj tau zoo formability thiab corrosion kuj.
S320GD galvanized hlau puas tuaj yeem welded?
Yog lawm. S320GD tuaj yeem welded siv cov txheej txheem vuam, tab sis kev ua pa kom zoo thiab kev npaj saum npoo yog pom zoo vim yog zinc txheej.
Puas yog S320GD haum rau kev sib sau txias?
Yog lawm. S320GD muaj zoo formability thiab yog haum rau yob txoj kev, dabtsi yog khoov, thiab txias shaping txheej txheem.
Dab tsi thickness ntau yog muaj rau S320GD galvanized steel?
S320GD galvanized steel feem ntau muaj los ntawm cov ntsuas nyias (ib puag ncig 0.35 hli) mus txog cov qauv tuab ntawm 6.0 hli lossis ntau dua, nyob ntawm qhov muaj peev xwm muab khoom.
Dab tsi nto tiav rau S320GD galvanized steel?
Cov txheej txheem saum npoo tiav suav nrog cov spangle li niaj zaus, minimized spangle, thiab xoom spangle, nyob ntawm daim ntawv thov.
S320GD + Z275 galvanized steel kav ntev npaum li cas?
Hauv ib puag ncig ib puag ncig, S320GD + Z275 tuaj yeem muab kev tiv thaiv corrosion rau 15-30 xyoo, nyob ntawm qhov raug mob.
