Ni327-3
GB/T ENi6625
Faʻamatalaga: Ni327 -3 o se eletise faʻavae nickel faʻatasi ai ma le paʻu sodium maualalo-hydrogen.Fa'aaoga le DCEP (fa'atonu eletise eletiselelei).O le u'amea teuina e sili ona lelei le palasitisi, faigata ma le ta'e tete'e, ma e maualuga le malosi ma le malosi o le pala i le potu vevela ma le vevela maualuga.
Talosaga: E faʻaaogaina mo le faʻapipiʻiina o uʻamea nickel-chromium-molybdenum, aemaise lava le faʻapipiʻiina ma le faʻafefe o UNS N06625 alloys ma isi ituaiga uʻamea ma nickel-chromium-molybdenum uʻamea tuʻufaʻatasia, ma e mafai foi ona faʻaaogaina mo le faʻaogaina o le Ni9% uamea i lalo. tulaga maualalo le vevela.
Su'ega vaila'au o u'amea u'amea(%):
| 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 | Isi |
| ≤7.0 | ≤0.5 | 3.0 ~ 4.2 | ≤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 | ≥760 | ≥420 | ≥27 |
Fautuaina le taimi nei:
| u'amea lautele （mm） | 2.5 | 3.2 | 4.0 |
| Uelotaimi nei （A） | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Fa'aaliga:
- 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;
- 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.
