A312
GB/T E309Mo-16
AWS A5.4 E309Mo-16
Kev piav qhia: A312 yog Cr23Ni13Mo2 stainless hlau electrode nrog titanium calcium txheej. Nws tuaj yeem siv rau ob qho tib si AC thiab DC nrog kev ua haujlwm zoo heev. Nws muaj kev xeb zoo dua, tawg, thiab oxidation tsis kam dua li A302 vim tias cov hlau tso muaj molybdenum.
Daim Ntawv Thov: Nws yog siv rau kev vuam tib hom stainless hlau thawv uas tiv taus corrosion los ntawm sulfuric acid medium (ammonia sulfide), thiab kuj tseem siv tau rau kev vuam stainless hlau hauv ob sab phlu, clad steel phaj thiab dissimilar steel.
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 150 ℃ ua ntej vuam ua haujlwm;
- Vim tias qhov tob ntawm qhov nkag mus rau hauv qhov chaw tsis tob thaum lub sijhawm vuam AC, yuav tsum siv lub zog DC kom ntau li ntau tau kom nkag mus tob dua. thiab tam sim no yuav tsum tsis txhob loj dhau kom tsis txhob liab ntawm tus pas vuam.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim muaj xyoo 2000. Peb tau koom nrog kev tsim cov vuam electrodes,cov pas nrig vuam, thiabcov khoom siv vuamtau ntau tshaj 20 xyoo.
