Molybdenum le Chromium Molybdenum Heat Resistant Steel Welding Electrode
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Tlhaloso: R407 ke electrode ea tšepe e sa keneleng mocheso ea pearlitic e nang le seaparo se tlaase sa hydrogen sodium se nang le 2.5% Cr - 1% Mo. Sebelisa DCEP (electrode e nepahetseng ea hona joale e nepahetseng) 'me e ka kenngoa libakeng tsohle.Weldment e tlameha ho futhumatsoa pele ho 200 ~ 300 ° C pele ho tjheseletsa.
Kopo: E sebelisetsoa ho tjheseletsa liphaephe tsa mocheso o phahameng le tse nang le khatello e phahameng ka mocheso o sebetsang o ka tlase ho 550 ° C, mechine ea lik'hemik'hale ea maiketsetso, lisebelisoa tsa ho senya peterole, joalo-joalo.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
| 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 |
Mechine ea tšepe ea weld:
| Ntho ea teko | Matla a tšepe Mpa | Ho hlahisa matla Mpa | Elongation % | Boleng ba tšusumetso (J) Tloaelehileng Temp. |
| Guaranteed | ≥590 | ≥490 | ≥15 | ≥47 |
| Lekoa | 600 ~ 680 | ≥500 | Lilemo tse 18-21 |
Likahare tsa hydrogen tsa tšepe e kentsoeng: ≤4.0mL/100g (mokhoa oa glycerin)
Tlhahlobo ea X-ray: Ke ea sehlopheng
Nako e khothalelitsoeng:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Tlhokomeliso:
1. Electrode e tlameha ho behoa ka hora e le 1 ho 350 ℃ pele ho ts'ebetso ea welding;
2. Ho bohlokoa ho hloekisa mafome, sekala sa oli, metsi le litšila holim'a likarolo tsa ho tjheseletsa pele ho tjheseletsa.
