3. Huab Cua Kuj
Corrosion tus nqi:
Nyob deb nroog: ~ 0.01 hli / xyoo (ruaj khov xeb txheej)
Muaj: Yuav tsum muaj kev tiv thaiv kev tiv thaiv (tsis sib xws patina muaj kev pheej hmoo)
Qhov Tseem Ceeb Alloying Ntsiab Lus:
Tooj Liab (Cu): 0.25-0.55% (txhim kho cov xeb xeb)
Chromium (cr): 0.40-1.25% (corrosion tsis kam)
Phosphorus (p): 0.06-0.15% (nrawm tiv Patina)
4. Fabrication & vuam
| Chaw ua uas tsis tau haus | Qhov toob kas |
|---|---|
| Carbon sib npaug (cet) | Tsawg dua los yog sib npaug rau 0.42 (zoo heev weldability) |
| Preheat kub | Feem ntau tsis tsim nyog (yog tias tsawg dua lossis sib npaug nrog 25mm) |
| Pom zoo electrode | En iso 2560-a: e 42 3 b}1 2 |
| Tej kev | Laser / Ntshav (zam kom zam oxyfuel) |
5. Cov qhab nia sib npaug
| Lub hom phiaj | Teem nqi | Qhov sib txawv |
|---|---|---|
| ASTM | A588 Qib K | Qis dua p (tsawg dua los yog sib npaug rau 0.04%), siab dua cu |
| JIS | Spa-h | Ntxiv NB rau cov tubrog tsis kam |
| GB / T | Q355NH | -40 Degree Cov Kev Cuam Tshuam (Stricter) |
6. Cov ntawv thov raug
Kev ua tsev: Cov choj, nthuav tawm cov ntawv ntas (piv txwv li, chaw nres tsheb Berlin)
Xa xov: Cov thawv xa khoom, Cheeb Tsam
Daim duab: Rust-Patina Sculptures (Ua Ntej Oxidation pom zoo)
7. Cov Ntawv Sau Tseg
Daim ntawv muaj cai: En {10204 3.1 b nrog tshav kub-traceability
Qhov xwm txheej nto: Qhia kom meej zeb teev lossis SA 2.5 blast-ntxuav
Kev Thov Tshwj Xeeb: Rau cov chaw hnyav, thov CU / CR / P ntawm cov kev txwv sab saud
