1. Cov Khoom Txheej Txheem
Spa - h yog qhov siab - kev ua tau zooHuab Cua Hlau(atmospheric corrosion -} Cov hlau tiv taus cov txheej txheem (shs, thiab, feeb). Nws tsim aTiv thaiv cov xeb (patina)Thaum raug rau huab cua, tshem tawm qhov xav tau kev xav tau ntawm kev tswj hwm thaum saib xyuas cov chaw hnyav hauv ib puag ncig.
2. Cov Nta Tseem Ceeb & Cov Cai
Zoo tshaj corrosion Kuj- 3-5 × zoo dua li cov roj carbon hlau hauv kev lag luam / marine cua tshuab
Tus kheej - tiv thaiv patina- Ua cov txheej txheej oxide ruaj khov, tiv thaiv kev xeb ntxiv corrosion
Siab Zog – 355 mpa min paib zog(cov qauv kev cai lij choj)
Tsawg txij nkawm- Tsis muaj kev rov ua dua, txo cov nqi kav lub neej
Eco - tus phooj ywg- 100% rov ua dua tshiab, txo cov kev tawm suab los ntawm cov txheej txheem
Zoo heev Weldability & Fabrication- Tau tshaj nrog cov qauv vuam / tej txheej txheem
3. Kev Tshwj Xeeb Cov Lus Qhia
Tshuaj lom neeg muaj pes tsawg leeg (ib leeg%)
| Lub ntsiab | Spa - h | Ua rau |
|---|---|---|
| C | Tsawg dua los yog sib npaug rau 0.12% | Txhim Kho Weldability |
| P | 0.07-0.15% | Accelerates tiv thaiv pata tsim |
| CU | 0.25-0.55% | Txhim kho corrosion tsis kam |
| Cr | 0.30-1.25% | Txhab Txhab Txheej |
| Si | 0.20-0.75% | Nce lub zog |
Cov Khoom Siv Neeg Kho Tshuab
| Ntiag tug | Tus nqi |
|---|---|
| Yield zog (RP0.2) | Ntau dua los yog sib npaug rau 355 mpa |
| Lub zog tensile (RM) | 470-630 MPa |
| Elongation (A₅) | Ntau dua los yog sib npaug rau 22% |
| Kev Cuam Tshuam Tais (J, -20 degree) | Ntau dua los yog sib npaug rau 27J |
