Nickel and *Nickel Alloy Welding Electrode
Ni307-4
GB/T ENi6093
AWS A5.11 ENiCrFe-4
Descriptio: Ni307-4 est electrode nickel substructio cum sodium humili-hydrogenis efficiens.Usus DCEP (rectum current electrodeaffirmativus).Habet compositionem optimam glutino cum arcubus stabilibus combustionem, spatorem minus, scoriam removentem facilem;
et pulchram pugillo.
Applicatio: Adhibetur ad mixturas mixturas nickel-chromium-ferreas, ut Ni600, Ni800/800H et similes vel nickel-fundantur superalloyia cum temperatura laboranti 900 ° C. Potest etiam adhiberi ad ferrum temperaturas humilis continens. Ni3% ~ 9%, ut ASTM A333, A334, A353, A522, A553 glutino adhiberi potest etiam pro dissimile metallum glutino inter Mo400, Ni825, ferrum immaculatum et ferrum admixtum humile.
Compositio chemica metallici solidi (%):
| C | Mn | Fe | Si | Ni | Cr | Mo | Nb + Ta | S | P |
| ≤0.20 | 1.0 ~ 5.0 | ≤12.0 | ≤1.0 | ≥60.0 | 13.0 ~ 17.0 | 1.0 ~ 3.5 | 1.0 ~ 3.5 | ≤0.015 | ≤0.020 |
Mechanica metallorum congeries;
| Test item | Distrahentes fortitudo Mpa | Cedat imperium Mpa | Prolongatio % |

Commendatur current:
| Rod diam mm） | 2.5 | 3.2 | 4.0 |
| Welding current A） | 60 ~ 90 | 80~ 110 | 110 ~ 150 |
Animadverte:
1. Electrodum coquendum est hora 1 circiter 300℃ ante operationem glutinum;
2. Essentiale est purgare ferruginem, oleum, aquam, et immunditias in partibus glutino ante glutino.Conare brevi arcum pactionem utere.
