Heerkulka hoose ee Birta alxanka Electrode
W707
GB/T E5015-G
AWS A5.5 E7015-G
Sharaxaad: W707 waa korantada birta ah ee heerkulka hooseeya oo leh daahan sodium-hydrogen 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 |
| ≤0.08 | ≤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 | ≥490 | ≥390 | ≥22 | ≥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 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Ogaysiis:
1. electrode waa in lagu dubaa 1 saac at 350 ℃ ka hor hawlgalka alxanka;
2. Isku day inaad isticmaasho tamar khadka yar marka alxanka, lakabka badan iyo alxanka baasaska badan.
