Nickel ndi Nickel Alloy Welding Electrode
N327
GB/T ENi6094
AWS A5.11 ENCrFe-9
Description: Ni327 ndi ma elekitirodi opangidwa ndi faifi tambala okhala ndi zokutira za hydrogen sodium.Gwiritsani ntchito DCEP (elekitirodi yamakonozabwino).Chitsulo choyikidwa chimakhala ndi mphamvu yolimbana ndi ming'alu chifukwa chowotcherera chimakhala ndi zinthu zina monga molybdenum ndi niobium.
Ntchito: Amagwiritsidwa ntchito powotcherera zitsulo za faifi tambala zomwe zimafuna kukana kutentha ndi kukana dzimbiri, komanso zimatha kugwiritsidwa ntchito kuwotcherera ndi kuyika ma aloyi ovuta kuwotcherera ndi zitsulo zosiyana.
Chemical zikuchokera weld zitsulo (%):
| 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 | Zina |
|
| 0.5 ~ 3.0 | 2.5 ~ 5.5 | ≤1.5 | ≤0.015 | ≤0.020 | ≤0.50 |
|
Zimango za weld zitsulo:
| Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % |
| Zotsimikizika | ≥650 | ≥360 | ≥18 |
Zomwe tikulimbikitsidwa:
| Ndodo diameter (mm) | 3.2 | 4.0 |
| Welding panopa (A) | 90-110 | 110 ~ 150 |
Zindikirani:
1. Elekitirodi iyenera kuphikidwa kwa ola limodzi mozungulira 300 ℃ isanayambe ntchito yowotcherera;
2. M'pofunika kuyeretsa dzimbiri, mafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.
