Elektrode-ka Alxanka Nikkel iyo Nikkel
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Sharaxaad: Ni327-4 waa elektroodh ku salaysan nikkel oo leh dahaadh sodium oo hooseeya. Isticmaal DCEP (elektroodh hadda toos ah).togan). Waxay leedahay waxqabad alxan oo aad u fiican oo leh gubasho qaanso oo deggan, xoq yar, iyo si fudud looga saaro slag,
iyo alxan qurux badan. Sifooyinka farsamada ee birta la dhigay waa kuwo deggan.
Codsiga: Waxaa loo isticmaalaa alxanka birta nickel-chromium-molybdenum ee kaarboon yar, sida Hastelloy C276, ASTM B574, B575, B619, B622, B626, waxaana sidoo kale loo isticmaali karaa alxanka birta kala duwan ee leh alxanka kale ee ku salaysan nikkel.
Halabuurka kiimikada ee birta alxanka (%):
| 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 | Kale |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Sifooyinka farsamada ee birta alxanka:
| Shayga tijaabada ah | Xoogga jiidista Mpa | Xoogga wax soo saarka Mpa | Kordhinta % |
| Dammaanad qaaday | ≥690 | ≥400 | ≥22 |
Hadda lagu taliyay:
| Dhexroorka usha (mm) | 2.5 | 3.2 | 4.0 |
| Hadda alxanka (A) | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Ogeysiis:
1. Elektroodka waa in la dubo 1 saac oo ku dhow 300℃ ka hor inta aan la isticmaalin alxanka. Isku day inaad isticmaasho qaanso gaaban si aad u alxanto!
2. Waa lagama maarmaan in la nadiifiyo miridhku, saliidda, biyaha, iyo wasakhda ku jirta qaybaha alxanka ka hor inta aan la alxanka.
3. Isku day inaad isticmaasho tamar yar oo xariiq ah marka aad alxanayso, alxanka lakabka badan leh iyo alxanka badan leh.
