Qhov txawv ntawm A500 Qib C thiab Qib B yog dab tsi?
1. Chemical Composition Differences (%)
A500GR.B muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, ua rau nws haum rau cov qauv siv dav dav. A500GR.C, nrog nws cov ntsiab lus siab dua me ntsis, muab lub zog tensile zoo dua thiab kev tiv thaiv corrosion, ua rau nws tsim nyog rau cov haujlwm uas yuav tsum tau muaj zog dua thiab kav ntev.
| Element | A500 Gr.B | A500 Gr.C | Qhov txawv tseem ceeb |
|---|---|---|---|
| Cov pa roj carbon (C) | Tsawg dua lossis sib npaug li 0.26 | Tsawg dua lossis sib npaug li 0.23 | Gr.C muaj cov ntsiab lus qis dua rau kev txhim kho weldability. |
| Manganese (Mn) | Tsawg dua lossis sib npaug li 1.35 | Tsawg dua lossis sib npaug li 1.40 | Kev nce me ntsis hauv Mn rau Gr.C los txhim kho lub zog. |
| Phosphorus (P) | Tsawg dua lossis sib npaug li 0.035 | Tsawg dua lossis sib npaug li 0.035 | Tib yam tswj nruj. |
| Sulfur (S) | Tsawg dua lossis sib npaug li 0.035 | Tsawg dua lossis sib npaug li 0.035 | Tib yam tswj nruj. |
| Silicon (Si) | Tsawg dua lossis sib npaug li 0.10 | Tsawg dua lossis sib npaug li 0.10 | Tsis txawv. |
2. Mechanical Property Sib txawv
| Khoom | A500 Gr.B | A500 Gr.C | Qhov txawv tseem ceeb |
|---|---|---|---|
| Yield zog | Ntau dua lossis sib npaug li 290 MPa | Ntau dua lossis sib npaug li 315 MPa | Gr.C muaj ~ 8.6% siab dua yield zog rau hnyav -load daim ntaub ntawv. |
| Tensile zog | 345-450 MPa | 380-480 MPa | Gr.C muaj lub zog ntau dua, haum rau qhov xav tau ib puag ncig. |
| Elongation | Ntau dua lossis sib npaug li 20% (50mm gauge) | Ntau dua lossis sib npaug li 18% (50mm gauge) | Kev txo qis hauv ductility rau Gr.C vim muaj zog dua. |
3. Kev ua tau zoo & Kev sib piv
| Yam | A500 Gr.B | A500 Gr.C |
|---|---|---|
| Weldability | Zoo heev (siab dua carbon hauv Gr.B tseem tswj tau) | Superior (qis carbon txo qhov kev pheej hmoo ntawm kev sib tsoo). |
| Tsim nyog Scenarios | Cov qauv kev txhawb nqa dav dav, tsis yog- qhov tseem ceeb load- cov kabmob. | Cov tshuab hnyav, siab -cov qauv kev ntxhov siab, qis- qhov kub thiab txias. |
| Nqi | qis | Me ntsis siab dua (vim muaj kev sib xyaw ua ke thiab kev sim). |
Ntau qhov kev tswj xyuas zoo tau siv thaum lub sij hawm tsim cov kav dej A500:
1. Kev tshuaj xyuas cov khoom siv raw: tshuaj lom neeg muaj pes tsawg leeg thiab kev ntsuas cov khoom siv hluav taws xob yog ua los ntawm cov hlau coils.
2. Kev saib xyuas online: Weld zoo yog tshuaj xyuas siv cov thev naus laus zis xws li kev ntsuas ultrasonic thiab kev ntsuas tam sim no.
3. Dimensional soj ntsuam: Sab nraud qhov ntev ntawm cov kav hlau steel tau saib xyuas hauv lub sijhawm tiag tiag uas siv lub laser txoj kab uas hla.
4. Kev ntsuam xyuas cov cuab yeej cuab tam: Kev ntsuam xyuas Tensile thiab kev ntsuas kev khoov yog ua los ntawm cov qauv ntawm txhua pawg ntawm cov khoom.
5. Kev kho deg: Feem ntau cov khoom siv galvanizing lossis pleev xim los txhim kho corrosion kuj.
