galvanized steel kauj
Xav tau siab -lub zog galvanized steel rau koj qhov project tsim? Koj twb tuaj rau qhov zoo lawm. Raws li lub Hoobkas tshaj lij nrog 20 xyoo ntawm kev paub steel, GNEE Steel khoom siv sab saum toj - zooS550GD galvanized steel kaujntawm tus nqi sib tw. Cov lus qhia no piav qhia vim li cas cov tshuaj muaj pes tsawg leeg ntawm S550GD (1.0531) yog qhov tseem ceeb rau nws txoj kev ua haujlwm.
Galvanized steel kauj
Galvanized steel coils yog qhov tseem ceeb hauv kev lag luam niaj hnub no. Lub zinc txheej tiv thaiv cov hlau los ntawm xeb, thaum lub hauv paus hlau muaj pes tsawg leeg txiav txim siab nws lub zog thiab formability. S550GD yog qib nrov rau siab -load daim ntawv thov, ua tsaug rau nws ua tib zoo tsim tshuaj pleev ib ce.
S550GD yog siab -lub zog qis- alloy (HSLA) galvanized steel. Nws yog tsim los siv cov qauv siv qhov twg ob lub zog thiab corrosion kuj xav tau.
1.0531 yog EN cov ntaub ntawv tsim tawm rau S550GD. Txoj cai no tau lees paub thoob ntiaj teb thiab ua kom cov hlau ua tau raws li cov qauv tshuaj lom neeg thiab cov txheej txheem nruj. Nws tshem tawm tsis meej pem ntawm cov qib steel sib txawv thiab lav zoo ib yam.
Sib piv S550GD (1.0531) Cov Khoom Siv Tshuaj nrog Lwm Cov Qib
Txhawm rau nkag siab S550GD qhov tsis sib xws, cia peb piv nws cov tshuaj muaj pes tsawg leeg nrog ob qib galvanized steel: DX51D thiab S350GD.
| Element | S550GD (1.0531) | xwm 51d | S350 GD |
|---|---|---|---|
| C (Max.%) | 0.12 | 0.12 | 0.12 |
| Si (Max.%) | 0.50 | 0.50 | 0.50 |
| Mn (Max.%) | 1.60 | 1.40 | 1.50 |
| P (Max.%) | 0.030 | 0.045 | 0.035 |
| S (Max.%) | 0.025 | 0.045 | 0.030 |
Cov ntsiab lus ntawm manganese ntau dua hauv S550GD (1.0531) yog qhov laj thawj tseem ceeb rau nws lub zog zoo dua piv rau DX51D thiab S350GD.
Chemical Composition's Impact on Galvanizing Quality
Lub hauv paus hlau muaj pes tsawg leeg cuam tshuam ncaj qha rau qhov zoo ntawm zinc txheej hauvS550GD galvanized steel kauj.
- Silicon cov ntsiab lus:Tswj cov tshuaj tiv thaiv ntawm cov hlau thiab molten zinc, kom ntseeg tau tias cov txheej txheem sib xws.
- Aluminium cov ntsiab lus:Txhim kho qhov adhesion ntawm zinc txheej, tiv thaiv tev tawm thaum tsim.
- Cov ntsiab lus carbon:Cov pa roj carbon ntau dhau tuaj yeem ua rau txheej txheej tsis xws luag, yog li nws nruj me ntsis txwv rau 0.12%.
- Phosphorus thiab sulfur:Cov qib qis tiv thaiv txheej txheej tsis zoo thiab ua kom lub ntsej muag du.
Mechanical Properties Derived los ntawm S550GD (1.0531) Composition
Cov tshuaj muaj pes tsawg leeg ntawm S550GD (1.0531) txhais rau kev ua haujlwm zoo heev:
| Mechanical Property | Tus nqi |
|---|---|
| Yield zog (Rp0.2) | Ntau dua lossis sib npaug li 550 MPa |
| Tensile zog (Rm) | 600-730 MPa |
| Elongation (A80 hli) | Ntau dua lossis sib npaug li 14% |
| Khoov Peev Xwm | 180℃tsis tawg |
Cov khoom no ua rau S550GD zoo tagnrho rau kev thauj khoom -cov kabmob xws li lub tsev thav duab thiab lub tsheb chassis.
S550GD Cov txheej txheem steel ntau lawm
Ntawm GNEE STEEL, peb nruj me ntsis tswj txhua qhov txuas txuas kom ntseeg tau tias txhua pawg ntawm S550GD galvanized steel muaj kev ua tau zoo thiab ua tau zoo kom tau raws li koj cov kev xav tau ntau yam.
