galvanized steel kauj
Nrhiav kev txhim khu kev qha galvanized steel coil lwm tus neeg nyob hauv Suav teb? Koj twb tuaj rau qhov zoo lawm. Raws li lub Hoobkas ncaj qha nrog 20 xyoo ntawm cov qauv steel kev paub, GNEE Steel muab siab - cov khoom zoo ntawm lub Hoobkas nqi. Hauv phau ntawv qhia no, peb yuav tsom mus rau cov tshuaj muaj pes tsawg leeg ntawmS550GD galvanized steel kaujthiab piav qhia nws cov khoom siv code 1.0531.
Galvanized steel yog hlau coated nrog zinc los tiv thaiv corrosion. Nws yog dav siv hauv kev tsim kho, tsheb, thiab hluav taws xob kev lag luam. Cov qib galvanized steel feem ntau suav nrog DX51D, S350GD, thiab S550GD, txhua tus muaj cov khoom tshwj xeeb rau kev siv sib txawv.

S550GD thiab 1.0531 Khoom siv yog dab tsi?
S550GD yog qib siab -lub zog galvanized steel qib. Lub "550" sawv cev rau nws qhov tsawg kawg nkaus tawm lub zog ntawm 550 MPa, thiab "GD" sawv cev rau kev siv cov qauv siv dav dav.
1.0531 yog EN (European Standard) cov ntaub ntawv tus lej rau S550GD. Txoj cai no ua kom muaj kev sib luag ntawm cov khoom zoo thoob plaws cov tuam txhab. Nws txhais cov tshuaj muaj pes tsawg leeg thiab cov cuab yeej cuab tam, ua kom yooj yim rau cov neeg yuav khoom los txheeb xyuas cov khoom siv.
Paub meej Chemical Composition Table ntawm S550GD (1.0531)
Cov tshuaj muaj pes tsawg leeg ntawm S550GD (1.0531) ncaj qha cuam tshuam rau nws qhov kev ua tau zoo. Hauv qab no yog cov txheej txheem muaj pes tsawg leeg:
| Element | Cov ntsiab lus (Max.%) | Lub luag haujlwm hauv Steel Performance |
|---|---|---|
| Cov pa roj carbon (C) | 0.12 | Txhim khu lub zog; tswj kom tsis txhob brittleness |
| Silicon (Si) | 0.50 | Txhim kho oxidation tsis kam thiab lub zog |
| Manganese (Mn) | 1.60 | Boosts tensile lub zog thiab hardenability |
| Phosphorus (P) | 0.030 | Txwv kom tsis txhob txias brittleness |
| Sulfur (S) | 0.025 | Txwv kom txo cov kub tawg thaum ua haujlwm |
| Aluminium (Al) | 0.015 (Min.) | Refines grain qauv kom zoo formability |
| Zinc (Zn) | Txheej: 60-275 g / m² | Muab kev tiv thaiv corrosion raws li txheej txheej |
S550GD Hlau Mechanical Properties
Ntxiv rau nws cov tshuaj lom neeg zoo heev, peb S550GD galvanized steel kuj muaj cov khoom siv zoo heev:
| Khoom | Metric | Imperial |

| Yield zog | Ntau dua lossis sib npaug li 550 MPa | Ntau dua lossis sib npaug rau 79.8 ksi |
| Brinell Hardness | 150-190 HB | 150-190 HB |
| Rockwell Hardness | 80-90 PAB | 80-90 PAB |
| Vickers Hardness | 160-200 HV | 160-200 HV |
| Elongation | 15-20% | 15-20% |
| Elastic Modulus | 210 GPa | 30,500 ksg |
| Fracture Elongation (tsawg dua lossis sib npaug li 0.7mm) | Ntau dua lossis sib npaug li 12% | Ntau dua lossis sib npaug li 12% |
| Fracture Elongation (>0.7 hli) | Ntau dua lossis sib npaug li 14% | Ntau dua lossis sib npaug li 14% |
| Txheej Adhesion (Bend Radius) | 0T-2T (0-2x thickness) | 0T-2T (0-2x thickness) |
Cov tshuaj muaj pes tsawg leeg cuam tshuam li cas S550GD Performance
Txhua lub hauv paus hauv S550GD (1.0531) ua lub luag haujlwm tseem ceeb hauv nws qhov kev ua tau zoo tag nrho.
- Cov pa roj carbon:Cov ntsiab lus carbon siab dua tuaj yeem ua rau muaj zog tab sis tuaj yeem txo qhov kev sib tw. Qhov 0.12% max txwv sib npaug zog thiab ua haujlwm tau zoo.
- Manganese:Txog li 1.60% Mn txhim kho lub zog yam tsis muaj kev tawg ntau dhau, zoo tagnrho rau kev siv cov qauv.
- Phosphorus thiab Sulfur:Kev tswj nruj nruj kom ntseeg tau tias cov hlau tuav tau zoo ductility thiab ua cov khoom.
- Aluminium:Ua raws li cov deoxidizer, txhim kho cov hlau huv thiab kev ruaj ntseg txhua yam.
