Kev piav qhia: J507 yog cov hlau electrode carbon nrog cov txheej hydrogen sodium tsawg. Cov hlau tso tawm muaj cov yas zoo, tawv, thiab tiv taus tawg. Siv DCEP (direct current electrode positive), thiab tuaj yeem vuam rau txhua qhov chaw.
Daim Ntawv Thov: Siv rau kev vuam ntawm cov hlau carbon nruab nrab thiab qee cov qauv hlau tsis tshua muaj hlau, xws li 09Mn2Si, Q345, 09Mn2V, thiab lwm yam.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | S | P |
| ≤0.12 | ≤1.60 | ≤0.75 | ≤0.035 | ≤0.035 |
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) | |
| -20℃ | -30℃ | ||||
| Tau lees paub | ≥490 | ≥400 | ≥22 | ≥47 | ≥27 |
| Tau kuaj xyuas | 520 ~ 580 | ≥410 | 24 ~ 32 | 60 ~ 230 | 55 ~ 200 |
Cov ntsiab lus hydrogen diffusion ntawm cov hlau tso: ≤8.0mL / 100g (txuj ci glycerin)
Kev tshuaj xyuas X-ray: Kuv qib

| Vuam tam sim no （Ib) | 40~ 70 | 60 ~ 90 | 90 ~ 130 | 140 ~ 180 | 170 ~ 210 | 210~ 260 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;
2. 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;
3. Siv txoj kev vuam luv luv thaum vuam. Txoj kev vuam nqaim yog qhov tsim nyog.
