Birta Heerkulka HoosealxankaElectrode
W707Ni
GB/T E5515-C1
Sharaxaad: W707Ni waa kolleydh bir ah oo heerkulka hooseeya ka kooban Ni oo ku jira daahan soodhiyam hooseeya.Isticmaal DCEP (electrode toos ah oo toos ah) oo ku alxan kara dhammaan boosaska.Birta la shubay ayaa wali saameyn wanaagsan ku leh adkaanta -70°C.
Codsiga: Waxaa loo isticmaalaa alxanka birta heerkulka hooseeya sida 2.5Ni.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % | Qiimaha saamaynta (J) -70 ℃ |
| La damaanad qaaday | ≥540 | ≥440 | ≥17 | ≥27 |
Waxyaalaha hydrogen firidhsan ee birta la shubay: ≤6.0mL/100g (hab glycerin) ama ≤10mL/100g (habka meerkuri ama gaaska chromatography)
Kormeerka raajada: Waxaan darajo
Hadda lagu taliyay:
| (mm) Dhexroor usheeda | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Alxanka Hadda | 40 ~ 70 | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Ogaysiis:
- Electrode waa in lagu dubaa 1 saac 350 ℃ ka hor hawlgalka alxanka;
- Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor;
- Isku day inaad isticmaashid tamarta xariiqda yar markaad alxanayso, lakabyo badan iyo alxanka baasaska badan.
