Kev piav qhia: W606Fe yog lub hlau electrode uas kub tsawg nrog hmoov hlau thiab txheej hydrogen potassium tsawg. Nws siv tau rau txhua qhov chaw vuam nrog AC thiab DC. Cov hlau uas tso rau hauv muaj qhov cuam tshuam zoo ntawm -60 ° C.
Daim Ntawv Thov: Siv rau vuam cov hlau kub qis xws li 2.5Ni.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤0.80 | 2.00 ~ 2.75 | ≤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) -60 ℃ |
| Tau lees paub | ≥540 | ≥440 | ≥17 | ≥27 |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤6.0mL / 100g (txheej txheem glycerin) lossis ≤10mL / 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 | 3.2 | 4.0 | 5.0 |
| (Ib) Vuam Tam Sim No | 90 ~ 120 | 140 ~ 180 | 180 ~ 210 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej kev vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, cov roj, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam.
