Molybdenum ma Chromium Molybdenum Heat Resistant Steel Welding Electrode
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Faʻamatalaga: R407 o se paʻu uʻamea faʻafefe pearlitic ma se paʻu sodium maualalo-hydrogen o loʻo i ai 2.5% Cr - 1% Mo. Faʻaaoga le DCEP (faʻaogaina o le eletise i le taimi nei) ma e mafai ona faʻafefe i tulaga uma.E tatau ona muaʻi faʻamafanafanaina le uelo i le 200 ~ 300 ° C aʻo leʻi faʻapipiʻiina.
Talosaga: Faʻaaogaina mo le faʻapipiʻiina o paipa maualuga-vevela ma maualuga faʻamalosi ma le vevela galue i lalo ole 550 ° C, masini vailaʻau faʻapipiʻi, mea faʻapipiʻi suauu, ma isi.
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 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤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 | ≥590 | ≥490 | ≥15 | ≥47 |
| Tofotofoina | 600 ~ 680 | ≥500 | 18 ~ 21 |
Fa'asalalauina o le hydrogen i totonu o le uamea ua teuina: ≤4.0mL/100g (auala glycerin)
Asiasiga X-ray: Ou te togi
Fautuaina le taimi nei:
| u'amea lautele （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Uelo Uila （A） | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Fa'aaliga:
1. E tatau ona tao le electrode mo le 1 itula i le 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.
