Ni327-3
GB/T ENi6625
Tsanangudzo: Ni327 -3 is nickel-based electrode ine low-hydrogen sodium coating.Shandisa DCEP (yakananga ikozvino electrodepositive).Simbi yakaiswa ine yakanakisa purasitiki, kuoma uye kutsemuka kuramba, uye ine simba rakawanda uye yakasimba corrosion kuramba pakupisa kwekamuri uye tembiricha yakakwira.
Chikumbiro: Inoshandiswa kubatanidza nickel-chromium-molybdenum alloys, kunyanya kukwenenzverwa nekuiswa pamusoro kweUNS N06625 alloys nedzimwe mhando dzesimbi uye nickel-chromium-molybdenum alloy composite steels, uye inogona zvakare kushandiswa kukwenenzvera Ni9% simbi pasi. pasi tembiricha mamiriro.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.10 | ≤2.0 | ≤0.8 | 20.0 ~ 23.0 | ≥55.0 | 8.0 ~ 10.0 |
| Fe | Cu | Nb + Ta | S | P | Zvimwe |
| ≤7.0 | ≤0.5 | 3.0 ~ 4.2 | ≤0.015 | ≤0.020 | ≤0.5 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % |
| Guaranteed | ≥760 | ≥420 | ≥27 |
Yazvino inokurudzirwa:
| Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 |
| Weldingcurrent (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Cherechedza:
- Iyo electrode inofanira kubikwa kweawa imwe panguva yakatenderedza 300 ℃ isati yaitwa welding.Edza kushandisa arc pfupi kuti weld;
- Zvakakosha kuchenesa dzine ngura, oiri, mvura, netsvina pazvikamu zvewelding tisati tasveta.
3. Edza kushandisa simba remutsara mudiki paunenge uchitsvaira, multi-layer uye multi-pass welding.
