Nickel uye Nickel Alloy Welding Electrode
Ni327-4
GB/T ENi6276
AWS A5.11 ENCrMo-4
Tsanangudzo: Ni327-4 is nickel-based electrode ine yakaderera-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrodepositive).Iyo ine yakanakisa welding performance ine yakagadzikana arc combustion, shoma spatter, nyore kubvisa slag,
uye weld yakanaka.Iyo mechanical properties yesimbi yakaiswa yakagadzikana.
Chikumbiro: Inoshandiswa kukwenenzvera yakaderera-kabhoni nickel-chromium-molybdenum alloys, seHastelloy C276, ASTM B574, B575, B619, B622, B626, uye inogona zvakare kushandiswa kugadzira masimbi akasiyana nemamwe nickel-based alloys.
Kemikari yakagadzirwa nesimbi weld (%):
| 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 | Zvimwe |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % |
| Guaranteed | ≥690 | ≥400 | ≥22 |
Yazvino inokurudzirwa:
| Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 |
| Welding ikozvino (A) | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Cherechedza:
1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 300 ℃ isati yaitwa welding.Edza kushandisa arc pfupi kuti weld;
2. Zvakakosha kuchenesa dzine ngura, oiri, mvura, uye tsvina pazvikamu zvinonamatwa tisati tapisa.
3. Edza kushandisa simba remutsara mudiki paunenge uchitsvaira, multi-layer uye multi-pass welding.
