Ni327-3
GB/T ENi6625
Whakaahuatanga: Ko te Ni327 -3 he electrode i runga i te nikel me te paninga konutai iti-waiwai.Whakamahia te DCEP (direct current electrodepai).He pai rawa te kirihou o te konganuku kua penapena, he pakari me te kapiti, he kaha te kaha me te kaha o te waikura i te pāmahana rūma me te pāmahana teitei.
Taupānga: Kei te whakamahia mo te whakakoi o te nickel-chromium-molybdenum alloys, ina koa ko te whakahiato me te papa o te UNS N06625 alloys me etahi atu momo maitai me te nickel-chromium-molybdenum alloys composite steels, a ka taea hoki te whakamahi mo te whakarewa Ni9% maitai i raro tikanga pāmahana iti.
Te hanganga matū o te whakarewa whakarewa(%):
| 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 | Ētahi atu |
| ≤7.0 | ≤0.5 | 3.0 ~ 4.2 | ≤0.015 | ≤0.020 | ≤0.5 |
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % |
| Ka whakamanahia | ≥760 | ≥420 | ≥27 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 |
| Wehenganāianei （A） | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Panui:
- Me tunu te hiko mo te 1 haora i te 300 ℃ i mua i te mahi fehokotaki.Ngana ki te whakamahi i te pewa poto ki te wea;
- He mea nui ki te horoi i te waikura, te hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.
3. Whakamātauria ki te whakamahi i te pūngao raina iti ina fehokotaki'anga, maha-apa me te maha-haere fehokotaki'anga.
