Nickel thiab Nickel Alloy Vuam Electrode
N307-3
GB/T ENi6182
AWS A5.11 ENiCrFe-3
Nqe lus piav qhia: Ni307-3 yog anpib tsib xee-raws li electrode nrog low-hydrogen sodium txheej.Siv DCEP (direct tam sim no electrode zoo).Nws muaj qhov ua kom tawg tau zoo vim tias cov vuam muaj qee qhov ntawm manganese, niobium, thiab lwm yam alloying ntsiab.
Daim ntawv thov: Nws yog siv rau vuam ntawmnpib tsib xee-chromium-hlau alloys (xws li UNS N06600) thiab surfacing ntawm hlau.Kev ua haujlwm kub feem ntau tsis siab tshaj 480 ° C, thiab kev ua haujlwm tawg yog qhov zoo.Haum rau atomic furnace siab hlab ntsha thiab tshuaj tank vuam.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Fe | P | S | Si | Cu |
| ≤ 0.10 | 5.0 ~ 10.0 | ≤10.0 | ≤ 0.020 | ≤ 0.015 | ≤1.0 | ≤0.5 |
| Ni | Ti | Mo | Nb | Ta | Lwm yam |
|
| ≥60.0 | ≤1.0 | 13.0-17.0 Nws | 1.0 ~ 3.5 hli | ≤ 0.30 | ≤0.50 |
|
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
| lav | ≥550 | ≥360 | ≥ 27 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 ib | 130 ~ 180 ib |
Daim ntawv ceeb toom:
1. Cov 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 los ntxuav cov xeb, roj, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam.Sim siv luv luv arc rau vuam.
