Molybdenum ma Chromium Molybdenum Heat Resistant Steel Welding Electrode
R306Fe
GB/T E5518-B2
AWS A5.5 E8018-B2
Faʻamatalaga: R306Fe o se pearlitic vevela-tetesua uʻamea electrode ma uʻamea paʻu ma maualalo hydrogen potassium ituaiga coating o loʻo i ai 1% Cr - 0.5% Mo. E mafai ona faʻaaogaina uma AC ma DC, ma e mafai ona faʻapipiʻiina i tulaga uma ma le faʻaogaina o le arc puupuu.O le preheating o le uelo ma le interlayer vevela e 160 ~ 250 °C i le taimi o uelo.
Fa'aoga: Fa'aaogaina mo le ueloina o le 1%Cr - 0.5%Mo pearlitic u'amea vevela (e pei o le 15CrMo), e pei o le fa'avevela fa'avevela paipa luga ma le vevela galue i lalo ole 550°C, paipa ausa ma va'a mamafa ma le vevela galue i lalo ole 520°C. , ma isi. E mafai ona faʻaaogaina mo le faʻapipiʻiina o uʻamea uʻamea 30CrMnSi.
Su'ega vaila'au o u'amea u'amea(%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 1.00 ~ 1.50 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
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) Temp masani. |
| Fa'amaonia | ≥540 | ≥440 | ≥47 | ≥27 |
| Tofotofoina | 550 ~ 640 | ≥450 | 20 ~ 28 | 105 ~ 150 |
Fa'asalalauina o le hydrogen i totonu o u'amea teuina: ≤6.0mL/100g (auala glycerin)
Asiasiga X-ray: Ou te togi
Fautuaina le taimi nei:
| u'amea lautele （mm） | 3.2 | 4.0 | 5.0 |
| Uelo Uila （A） | 100 ~ 130 | 140 ~ 180 | 180 ~ 210 |
Fa'aaliga:
1. E tatau ona tao le eletise mo le 1 itula ile 350 ℃ aʻo leʻi faʻaogaina 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.
