AWS A5.5 E8018-C1
Faʻamatalaga: W606Fe o se eletise uʻamea maualalo-vevela ma le paʻu uʻamea ma le faʻapipiʻi maualalo o le hydrogen potassium.E mafai ona faʻaaogaina mo le faʻapipiʻiina o tulaga uma ma AC ma DC.O le u'amea teuina e lelei le malosi o a'afiaga ile -60°C.
Fa'aoga: Fa'aaogaina mo le ueloina o le sila maualalo vevela pei ole 2.5Ni.
Su'ega vaila'au o u'amea u'amea(%):
C | Mn | Si | Ni | S | P |
≤0.12 | ≤1.25 | ≤0.80 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Tulaga fa'ainisinia o u'amea u'amea:
Su'ega mea | Malosi fa'asa Mpa | Tuuina atu le malosi Mpa | Fa'aumiumi % | Tau a'afiaga (J) -60℃ |
Fa'amaonia | ≥540 | ≥440 | ≥17 | ≥27 |
Fa'asalalauina o le hydrogen i totonu o u'amea ua teuina: ≤6.0mL/100g (metotia glycerin) po'o le ≤10mL/100g (mecury po'o le gas chromatography method)
Asiasiga X-ray: Ou te togi
Fautuaina le taimi nei:
(mm) u'amea lautele | 3.2 | 4.0 | 5.0 |
(A) Uelo Uila | 90 ~ 120 | 140 ~ 180 | 180 ~ 210 |
Fa'aaliga:
1. E tatau ona tao le electrode mo le 1 itula i le 350 ℃ aʻo leʻi faia le faʻaogaina;
2. E taua tele le fa'amamāina o le ele, fua o le suau'u, vai, ma mea leaga i luga o vaega uelo a'o le'i uelo.
