Nikkel iyo nikkel Alloy alxanka Electrode
Ni327
GB/T ENi6094
AWS A5.11 ENiCrFe-9
Sharaxaad: Ni327 waa koronto-ku-saleysan nikkel oo leh daahan sodium-hydrogen hooseeya.Isticmaal DCEP (electrode toos ah haddatogan).Birta la shubay waxay leedahay iska caabin dildilaac ah oo wanaagsan sababtoo ah alxanka waxaa ku jira xaddi gaar ah oo walxo alwaax ah sida molybdenum iyo niobium.
Codsiga: Waxa loo isticmaalaa alxanka alxanka nikkel ee u baahan iska caabbinta kulaylka iyo iska caabinta daxalka, waxaana sidoo kale loo isticmaali karaa alxanka iyo dusha sare ee qaar ka mid ah alwaaxyada adag ee alxanka iyo birta la midka ah.
Halabuurka kiimikada ee birta alxanka (%):
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 | Mid kale |

Qalabka makaanikada ee birta alxanka:
Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % |
La damaanad qaaday | ≥650 | ≥360 | ≥18 |
Hadda lagu taliyay:
Dhexroor usheeda (mm) | 3.2 | 4.0 |
Hadda alxanka (A) | 90 ~ 110 | 110 ~ 150 |
Ogaysiis:
1. Elektroodka waa in lagu dubaa 1 saac ku dhawaad 300℃ ka hor alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.
