R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Tlhaloso: R407 ke electrode ea tšepe e hanelang mocheso ea perelalitic e nang le sekoahelo sa sodium se nang le haeterojene e tlase se nang le 2.5% Cr - 1% Mo. Sebelisa DCEP (electrode ea hona joale e tobileng) 'me e ka kopanngoa maemong 'ohle. Ho kopanngoa ho tlameha ho chesoa ho fihlela ho 200 ~ 300°C pele ho kopanngoa.
Tšebeliso: E sebelisoa bakeng sa ho tjheseletsa liphaephe tse nang le mocheso o phahameng le khatello e phahameng tse nang le mocheso o sebetsang ka tlase ho 550°C, mechini ea lik'hemik'hale ea maiketsetso, lisebelisoa tsa ho petsoha ha peterole, jj.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| 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 |
Litšobotsi tsa mechini tsa tšepe e welded:
| Ntho ea teko | Matla a tšepe Mpa | Matla a tlhahiso Mpa | Ho lelefatsa % | Boleng ba tšusumetso (J) Mocheso o Tloaelehileng. |
| E tiiselitsoe | ≥590 | ≥490 | ≥15 | ≥47 |
| E lekiloe | 600 ~ 680 | ≥500 | 18 ~ 21 |
Tekanyo ea haedrojene e hasaneng ea tšepe e bolokiloeng: ≤4.0mL/100g (mokhoa oa glycerin)
Tlhahlobo ea X-ray: Kereiti ea I
Khoeli e khothaletsoang:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| ho tjheseletsa hona joale (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong oa 350℃ pele ho ts'ebetso ea ho tjheseletsa;
2. Ho bohlokoa ho hlwekisa mafome, sekala sa oli, metsi le litšila likarolong tsa ho tjheseletsa pele ho tjheseletsa.
