Nickel and Nickel Alloy Welding Electrode
Ni307-3
GB/T ENi6182
AWS A5.11 ENiCrFe-3
Whakaahuatanga: Ni307-3 he anickel-i runga i te hiko me te paninga konutai iti-waiwai.Whakamahia te DCEP (te hiko tika o naianei pai).He pai te parenga kapiti na te mea kei roto i te weld te nui o te konupora, te niobium, me etahi atu mea whakauru.
Taupānga: Kei te whakamahia te reira mo te fehokotaki'anga onickel-Kōroma-rino koranu (pērā i UNS N06600) me te papa o te maitai.Ko te tikanga kaore i teitei ake i te 480 ° C te pāmahana mahi, a he pai te aukati kapiti.E tika ana mo te oko pehanga oumu ngota me te raima tank matū.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Fe | P | S | Si | Cu |
| ≤0.10 | 5.0 ~ 10.0 | ≤10.0 | ≤0.020 | ≤0.015 | ≤1.0 | ≤0.5 |
| Ni | Ti | Mo | Nb | Ta | Ētahi atu |
|
| ≥60.0 | ≤1.0 | 13.0 ~ 17.0 | 1.0 ~ 3.5 | ≤0.30 | ≤0.50 |
|
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % |
| Ka whakamanahia | ≥550 | ≥360 | ≥27 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Waehere naianei （A） | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Panui:
1. Me tunuhia te electrode mo te 1 haora i te taha o te 300 ℃ i mua i te mahi fehokotaki'anga;
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.Ngana ki te whakamahi i te pewa poto ki te wea.
