Elektrode-ka Birta Heerkulka Hoose
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Sharaxaad: W107 waa elektarood bir ah oo heerkul hooseeya leh oo leh dahaadh sodium ah oo hooseeya.Isticmaal DCEP (elektroodka tooska ah ee hadda jira ee wanaagsan) waxaadna ku dhejin kartaa dhammaan boosaska. Birta la dhigay wali waxay leedahay adkeysi saameyn oo wanaagsan oo ah -100°C.
Codsiga: Waxaa loo isticmaalaa alxanka birta heerkulka hooseeya sida 3.5Ni.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Sifooyinka farsamada ee birta alxanka:
|
Shayga tijaabada ah |
Xoogga jiidista Mpa |
Xoogga wax soo saarka Mpa | Kordhinta% | Qiimaha saameynta (J) -100℃ |
|
Dammaanad qaaday | ≥490 | ≥390 | ≥22 | ≥27 |
Fidinta haydarojiin ee birta la dhigay: ≤4.0mL/100g (habka glycerin) ama ≤7.0mL/100g (habka mercury ama gaaska chromatography)
Baarista raajada: Darajada I
Hadda lagu taliyay:
| (mm) Dhexroorka usha | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Hadda alxanka | 40 ~ 70 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
Ogeysiis:
- Elektroodka waa in la dubo 1 saac heerkul ah 350℃ ka hor inta aan la isticmaalin alxanka;
- Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda ku jirta qaybaha alxanka ka hor alxanka;
- Isku day inaad isticmaasho tamar yar oo khadka ah marka aad alxanayso, alxanka lakabka badan leh iyo alxanka badan leh.
