Nickel thiab Nickel Alloy Vuam Electrode
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Kev piav qhia: Ni327-4 yog ib lub electrode uas muaj nickel nrog cov txheej sodium hydrogen tsawg. Siv DCEP (direct current electrode)zoo). Nws muaj kev ua tau zoo heev nrog kev sib txuas ruaj khov arc, tsawg dua spatter, yooj yim tshem tawm slag,
thiab zoo nkauj vuam. Cov khoom siv kho tshuab ntawm cov hlau tso rau ruaj khov.
Daim Ntawv Thov: Siv rau kev vuam cov hlau nickel-chromium-molybdenum uas tsis muaj carbon ntau, xws li Hastelloy C276, ASTM B574, B575, B619, B622, B626, thiab kuj siv tau rau kev vuam cov hlau sib txawv nrog lwm cov hlau nickel.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.02 | ≤1.0 | ≤0.2 | 14.5 ~ 16.5 | ≥50.0 | 15.0 ~ 17.0 |
| W | Co | Fe | S | P | Lwm yam |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % |
| Tau lees paub | ≥690 | ≥400 | ≥22 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 2.5 | 3.2 | 4.0 |
| Vuam tam sim no (Ib) | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 300 ℃ ua ntej vuam ua haujlwm. Sim siv lub arc luv luv los vuam;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam.
3. Sim siv lub zog me me ntawm txoj kab thaum vuam, ntau txheej thiab ntau txoj kev vuam.
