Electrode alxanka Alloy Low
J707
GB/T E7015-D2
AWS E10015-D2
Sharaxaad: J707 waa bir bir ah oo aad u hooseeya oo hooseeya oo leh daahan sodium-hydrogen hooseeya.Isticmaal DCEP (electrode toos ah oo toos ah), waxaana lagu alxan karaa dhammaan boosaska.Marka loo baahdo, alxanka waa la sii kululayn karaa ka hor alxanka iyo dabci alxanka ka dib.
Codsiga: Inta badan waxaa loo isticmaalaa alxanka 15MnMoV, 14MnMoVB, 18MnMoNb iyo qaababka kale ee bir-daawaha hoose.Qaab dhismeedka alxanku wuxuu ku shaqayn karaa xaalada alxanka ama heerkulka (500 ~ 650 ℃).
Halabuurka kiimikada ee birta alxanka (%):

| C | Mn | Si | Mo | S | P |
| La damaanad qaaday | ≤0.15 | 1.65 ~ 2.00 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.040 |
| La tijaabiyay | 0.073 | 1.68 | 0.54 | 0.40 | 0.011 | 0.018 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % | Qiimaha saamaynta (J) -30℃ |
| La damaanad qaaday | ≥690 | ≥590 | ≥15 | ≥27 |
| La tijaabiyay | 720 | 610 | 18.6 | - |
Mawduuca hydrogen firdhinta ee birta kaydsan: ≤4.0mL/100g (habka glycerin)
Kormeerka raajada: Waxaan darajo
Hadda lagu taliyay:
| (mm) Dhexroor usheeda | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Alxanka Hadda | 60 ~ 100 | 100 ~ 140 | 140 ~ 190 | 190 ~ 250 |
Ogaysiis:
1. electrode waa in lagu dubaa 1 saac at 350 ~ 380 ℃ ka hor hawlgalka alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor;
3. Isticmaal qalliin gaaban marka alxanka la samaynayo.Jidka alxanka cidhiidhiga ah ayaa habboon.
