Nikel lan Nikel Alloy Welding Electrode
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Katrangan: Ni327-4 minangka elektroda adhedhasar nikel kanthi lapisan sodium hidrogen rendah.Gunakake DCEP (elektroda arus searahpositif).Wis kinerja welding banget karo pembakaran busur stabil, kurang spatter, gampang njabut slag,
lan las ayu.Sifat mekanik logam sing disimpen stabil.
Aplikasi: Digunakake kanggo welding wesi karbon rendah nikel-kromium-molybdenum, kayata Hastelloy C276, ASTM B574, B575, B619, B622, B626, lan uga bisa digunakake kanggo welding baja beda karo wesi basis nikel liyane.
Komposisi kimia saka logam las (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.02 | ≤1.0 | ≤0.2 | 14.5 ~ 16.5 | ≥50.0 | 15.0 ~ 17.0 |
| W | Co | Fe | S | P | Liyane |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0,015 | ≤0,020 | ≤0.5 |
Sifat mekanik logam las:
| Item tes | Kekuwatan tensile Mpa | kekuatan ngasilaken Mpa | Elongation % |
| Dijamin | ≥690 | ≥400 | ≥22 |
Saiki sing disaranake:
| diameteripun rod (mm) | 2.5 | 3.2 | 4.0 |
| Welding saiki （A） | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Kabar:
1. Elektroda kudu dipanggang for1 jam ing watara 300 ℃ sadurunge welding operasi.Coba gunakake busur cendhak kanggo ngelas;
2. Penting kanggo ngresiki Rusty, lenga, banyu, lan impurities ing bagean welding sadurunge welding.
3. Coba nggunakake energi baris cilik nalika welding, multi-lapisan lan multi-pass welding.
