Cov Hlau Kub Qis Tshaj Plaws Vuam Electrode
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Kev piav qhia: W107 yog lub electrode hlau kub qis nrog cov txheej txheem sodium hydrogen qis.Siv DCEP (direct current electrode positive) thiab tuaj yeem vuam rau txhua qhov chaw. Cov hlau uas tau tso tseg tseem muaj kev cuam tshuam zoo ntawm -100 ° C.
Daim Ntawv Thov: Siv rau vuam cov hlau kub qis xws li 3.5Ni.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Ni | S | P |
| ≤0.05 | ≤1.25 | ≤0.60 | 3.00 ~ 3.75 | ≤0.020 | ≤0.025 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
|
Khoom sim |
Lub zog tensile Mpa |
Lub zog tawm los Mpa | Kev ntev% | Tus nqi cuam tshuam (J) -100 ℃ |
|
Tau lees paub | ≥490 | ≥390 | ≥22 | ≥27 |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤4.0mL / 100g (txheej txheem glycerin) lossis ≤7.0mL / 100g (txheej txheem mercury lossis roj chromatography)
Kev tshuaj xyuas X-ray: Kuv qib
Pom zoo tam sim no:
| (hli) Txoj kab uas hla ntawm tus pas nrig | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (Ib) Vuam Tam Sim No | 40 ~ 70 | 70 ~ 90 | 90 ~ 130 | 140 ~ 180 | 180 ~ 240 |
Daim Ntawv Ceeb Toom:
- Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
- Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, roj nplai, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam;
- Sim siv lub zog me me ntawm txoj kab thaum vuam, ntau txheej thiab ntau txoj kev vuam.
