Nickel thiab Nickel Alloy Vuam Electrode
Ni327
GB/T ENi6094
AWS A5.11 ENiCrFe-9
Kev piav qhia: Ni327 yog ib lub electrode uas muaj nickel nrog cov txheej sodium hydrogen tsawg. Siv DCEP (direct current electrode)zoo). Cov hlau uas tau tso rau hauv muaj qhov tiv taus tawg zoo vim tias qhov vuam muaj qee qhov ntawm cov khoom sib xyaw xws li molybdenum thiab niobium.
Daim Ntawv Thov: Nws yog siv rau kev vuam cov hlau nickel uas xav tau kev tiv thaiv cua sov thiab kev tiv thaiv corrosion, thiab kuj tseem siv tau rau kev vuam thiab surfacing ntawm qee cov hlau nyuaj-rau-weld thiab cov hlau sib txawv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Fe | Si | Cu | Ni | Cr |
| ≤0.15 | 1.0 ~ 4.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥55.0 | 12.0 ~ 17.0 |
| Nb + Ta | Mo | W | S | P | Lwm yam |
|
| 0.5 ~ 3.0 | 2.5 ~ 5.5 | ≤1.5 | ≤0.015 | ≤0.020 | ≤0.50 |
|
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 | ≥650 | ≥360 | ≥18 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 3.2 | 4.0 |
| Vuam tam sim no (Ib) | 90 ~ 110 | 110 ~ 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;
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.
