A317
GB/T E309Mo-15
AWS A5.4 E309Mo-15
Kev piav qhia: A317 yog lub electrode hlau tsis xeb nrog cov txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive). Nws muaj kev tiv thaiv corrosion, tawg, thiab oxidation zoo dua li A302 vim tias cov hlau tso muaj molybdenum.
Daim Ntawv Thov: Nws yog siv rau kev vuam tib hom stainless hlau, composite steel phaj thiab cov hlau sib txawv uas tiv taus sulfuric acid medium (sulfur ammonia) corrosion.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.12 | 0.5 ~ 2.5 | ≤0.90 | 22.0 ~ 25.0 | 12.0 ~ 14.0 | 2.0 ~ 3.0 | ≤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 250 ℃ 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.
