Nikeli ma le nikeli u'umea fa'aeletise
Ni327-4
GB/T ENi6276
AWS A5.11 ENiCrMo-4
Faʻamatalaga: Ni327-4 o se eletise faʻavae nickel ma le paʻu sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletiselelei).E sili ona lelei le fa'auluuluga fa'atasi ma le fa'amumu arc mautu, fa'aitiitia le spatter, faigofie ona aveese le slag,
ma uelo matagofie.O mea faʻainisinia o le uʻamea teuina e mautu.
Fa'aoga: Fa'aoga mo le ueloina o u'amea nickel-chromium-molybdenum maualalo-carbon, e pei o Hastelloy C276, ASTM B574, B575, B619, B622, B626, ma e mafai fo'i ona fa'aoga mo le ueloina o u'amea eseese ma isi u'amea fa'avae nickel.
Su'ega vaila'au o u'amea u'amea(%):
| 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 | Isi |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Tulaga fa'ainisinia o u'amea u'amea:
| Su'ega mea | Malosi fa'asa Mpa | Tuuina atu le malosi Mpa | Fa'aumiumi % |
| Fa'amaonia | ≥690 | ≥400 | ≥22 |
Fautuaina le taimi nei:
| u'amea lautele （mm） | 2.5 | 3.2 | 4.0 |
| Uu fa'asolo （A） | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Fa'aaliga:
1. E tatau ona tao le eletise mo le 1 itula ile 300 ℃ aʻo leʻi faʻaogaina le faʻaogaina.Taumafai e fa'aoga se arc pupuu e uelo;
2. E taua tele le fa'amamāina o le ea, suau'u, vai, ma mea leaga i luga o vaega uelo a'o le'i uelo.
3. Taumafai e faʻaaoga le malosi o le laina laʻititi pe a faʻapipiʻi, faʻapipiʻi faʻapipiʻi ma multi-pass.
