A307
GB/T E309-15
AWS A5.4 E309-15
Kev piav qhia: A302 yog Cr23Ni13 stainless hlau electrode nrog cov txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive) thiab tuaj yeem welded rau txhua qhov chaw. Cov hlau tso tawm muaj kev tiv thaiv kev tawg zoo thiab kev tiv thaiv oxidation.
Daim Ntawv Thov: Siv rau kev vuam tib hom hlau tsis xeb, hlau zoo li tus, hlau chromium siab, hlau manganese siab, thiab lwm yam.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.15 | 0.5 ~ 2.5 | ≤0.90 | 22.0 ~ 25.0 | 12.0 ~ 14.0 | ≤0.75 | ≤0.75 | ≤0.030 | ≤0.040 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim |
Lub zog tensile Mpa | Kev ntev % |
| Tau lees paub | ≥550 | ≥25 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No (Ib) | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Daim Ntawv Ceeb Toom:
Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 150 ℃ ua ntej vuam ua haujlwm.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim muaj xyoo 2000. Peb tau koom nrog kev tsim khoom ntawmvuam electrodes, cov pas nrig vuam, thiabcov khoom siv vuamtau ntau tshaj 20 xyoo.
