Xov xwm
Rau kev tsim kho thiab kev lag luam hauv cov huab cua txias (kub qis li -40 degree), GNEE Steel'sS320GD galvanized steel ntawvtau ua pov thawj tias yog ib qho khoom siv tsis tau, ua tsaug rau nws qhov tshwj xeeb qis -kub toughness thiab tsis kam rau nkig tawg. Tsis zoo li ntau cov qauv hlau uas poob ductility nyob rau hauv khov, S320GD tuav nws cov kev ua tau zoo txawm tias nyob rau hauv huab cua txias, ua rau nws zoo tagnrho rau arctic warehouses, txias - chaw cia khoom, thiab offshore qauv nyob rau hauv sab qaum teb cheeb tsam.
Galvanized steel ntawv
Qhov qis -kub toughness ntawm S320GD yog rooted nyob rau hauv nws optimized tshuaj muaj pes tsawg leeg thiab txheej txheem tsim. Kev tswj nruj ntawm cov ntsiab lus phosphorus (tsawg dua lossis sib npaug li 0.10%) thiab kev siv cov khoom siv microalloying (piv txwv li, manganese) tiv thaiv kev tsim cov theem nkig hauv cov hlau, xyuas kom nws khaws nws cov elongation tus nqi (Ntau dua lossis sib npaug li 20%) thiab cuam tshuam tsis kam ntawm sub- xoom kub. Tsis tas li ntawd, qhov kub-dub zinc txheej tseem nyob hauv qhov chaw txias, tsis txhob tev lossis tawg uas tuaj yeem ua rau xeb.
Hauv qhov thib peb- cov kev xeem thib peb tau ua ntawm -40℃, S320GD tau pom Charpy V-notch cuam tshuam lub zog ntawm Ntau dua lossis sib npaug rau 27J-zoo tshaj qhov kev lag luam yam tsawg kawg nkaus ntawm 20J- lees paub tias nws muaj peev xwm tiv taus qhov cuam tshuam tam sim ntawd (piv txwv li, cua loads. Qhov kev ua tau zoo no, ua ke nrog nws lub zog tawm los siab (Ntau dua lossis sib npaug ntawm 320MPa) thiab kev tiv thaiv corrosion, ua rau nws yog qhov kev xaiv sab saum toj rau cov qauv kev nyab xeeb huab cua.
Hauv qab no yog cov ntsiab lus ntawm S320GD qhov qis- qhov ntsuas kub ua tau zoo:
| Kev kuaj mob | Txoj Kev Xeem | S320GD kev ua haujlwm | Kev lag luam Standard (yam tsawg) |
|---|---|---|---|
| Tsawg-Tsub Muaj Zog Hluav Taws Xob (-40 degree) | Charpy V-Ntawv | Ntau dua lossis sib npaug li 27J | Ntau dua lossis sib npaug li 20J |
| Elongation ntawm -30 degree | Tensile Test | Ntau dua lossis sib npaug li 18% | Ntau dua lossis sib npaug li 15% |
| Txheej Adhesion ntawm -40 degree | Khoov Test (180 degree) | Tsis Peeling | Tsis Peeling |
| Brittle Fracture Resistance (-40 degree) | Poob Nyhav Test | Tsis Muaj Fracture | Tsis Muaj Fracture |
"Txoj haujlwm huab cua txias tam sim no muaj kev sib tw tshwj xeeb- cov khoom siv yuav tsum muaj zog, corrosion- tiv taus, thiab tawv txaus los tswj qhov kub thiab txias," said tus thawj coj muag khoom ntawm GNEE Steel. "Peb cov ntawv S320GD galvanized steel tau siv nyob rau hauv txias- cov chaw khaws cia thiab cov kev tsim kho hauv Arctic thoob ntiaj teb, nrog xoom qhia txog kev tawg lossis kev ua haujlwm tsis zoo."
GNEE Steel muaj S320GD nyob rau hauv thicknesses xws li 0.8mm mus rau 3.0mm, nrog zinc txheej qib Z180-Z350 kom phim cov corrosion txaus ntshai ntawm qhov sib txawv txias- huab cua puag ncig. Peb kuj muab cov ncauj lus kom ntxaws txog kev ua haujlwm kub qis rau kev ua raws li qhov project.Hu rau peb tam sim no los tham txog koj qhov txias txias - huab cua qhov yuav tsum tau ua thiab ua kom lub Hoobkas ruaj ntseg - ncaj qha 2026 nqe nqe lus rau S320GD!
