Nickel and Nickel Alloy Welding Electrode
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Whakaahuatanga: Ko te Ni327-4 he electrode-nikeli me te paninga konutai iti-hydrogen.Whakamahia te DCEP (direct current electrodepai).He pai rawa te mahi fehokotaki'anga me te mura o te arc, he iti ake te mokamoka, he ngawari te tango para,
me te paihere ataahua.Ko nga ahuatanga miihini o te konganuku kua penapena he pumau.
Taupānga: Ka whakamahia mo te whakapiri i nga koranu nickel-chromium-molybdenum iti-carbon, penei i te Hastelloy C276, ASTM B574, B575, B619, B622, B626, a ka taea hoki te whakamahi mo te whakapiri i nga tira rereke me etahi atu koranu nickel-based.
Te hanganga matū o te whakarewa whakarewa(%):
| 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 | Ētahi atu |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤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 | ≥690 | ≥400 | ≥22 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 |
| Waehere naianei （A） | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Panui:
1. Me tunu te electrode mo te 1 haora i te 300 ℃ i mua i te mahi fehokotaki.Ngana ki te whakamahi i te pewa poto ki te wea;
2. 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.
