Nikeli ma le nikeli u'umea fa'aeletise
Ni307-2
GB/T ENi6133
AWS A5.11ENiCrFe-2
Faʻamatalaga: Ni307-2 o se eletise faʻavae nickel ma le paʻu sodium maualalo-hydrogen.Fa'aaogā le DCEP (fa'atonu eletise eletise i le taimi nei).Talu ai ona o le uelo o loʻo i ai se aofaʻi o le molybdenum, niobium ma isi elemene faʻafefiloi, o le uʻamea teuina e lelei le teteʻe.
Talosaga: Faʻaaogaina mo le faʻapipiʻiina o uʻamea nickel-chromium-uʻamea (e pei o le UNS N08800, UNS N06600), aemaise lava mo le faʻapipiʻiina o metala eseese, faʻafeiloaʻiga o le faʻaogaina ma le faʻapipiʻiina o luga, ma e mafai foi ona faʻaaogaina pe a oʻo i le 980 ° C le vevela galue, ae e mafai ona tetee oxidation pe a maualuga le vevela nai lo 820 ° C Fa'aitiitia feusuaiga ma le malosi.
Su'ega vaila'au o u'amea u'amea(%):
| C | Mn | Fe | Si | Cu | Ni |
| ≤0.10 | 1.0 ~ 3.5 | ≤12.0 | ≤0.8 | ≤0.5 | ≥62.0 |
| Cr | Nb + Ta | Mo | S | P | Isi |
| 13.0 ~ 17.0 | 0.5 ~ 3.0 | 0.5 ~ 2.5 | ≤0.015 | ≤0.020 | ≤0.50 |
Tulaga fa'ainisinia o u'amea u'amea:
| Su'ega mea | Malosi fa'asa Mpa | Tuuina atu le malosi Mpa | Fa'aumiumi % |
| Fa'amaonia | ≥550 | ≥360 | ≥27 |
Fautuaina le taimi nei:
| u'amea lautele （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Uu fa'asolo （A） | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Fa'aaliga:
1. E tatau ona tao le eletise mo le 1 itula i le 300 ℃ aʻo leʻi faʻaogaina le faʻaogaina;
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.Taumafai e fa'aoga se arc pupuu e uelo ai.
