GB/T E430-16
AWS E430-16
Kev piav qhia: G302 yog Cr17 stainless hlau electrode nrog titanium-calcium txheej. Nws tuaj yeem siv nrog AC thiab DC.
Daim Ntawv Thov: Siv rau kev vuam cov qauv hlau tsis xeb (nitric acid) thiab cov qauv hlau tsis xeb Cr17 uas tiv taus cua sov.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.10 | ≤1.0 | ≤0.90 | 15.0 ~ 18.0 | ≤0.6 | ≤0.75 | ≤0.75 | ≤0.03 | ≤0.04 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Kev ntev % |
| Tau lees paub | ≥450 | ≥20 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No (Ib) | 80 ~ 120 | 100 ~ 160 | 150 ~ 200 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 150 ℃ ua ntej welding ua haujlwm;
2. Qhov welded yuav tsum tau preheated ntawm li 200 ° C ua ntej welding.
