Kev piav qhia: A042 yog lub electrode stainless hlau Cr23Ni13Mo2 uas muaj cov pa roj carbon tsawg heev nrog titanium calcium txheej. Nws tuaj yeem siv rau ob qho tib si AC thiab DC. Vim yog ntxiv cov molybdenum kom txaus, qhov kev tiv thaiv kab nrib pleb thiab kev tiv thaiv corrosion ntawm cov hlau tso tau zoo dua.
Daim Ntawv Thov: Rau tib hom ultra-low carbon stainless hlau cov ntaub ntawv (xws li urea synthesis tower lining) thiab dissimilar steel welding, thiab lwm yam.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.04 | 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 | ≥520 | ≥25 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No (Ib) | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 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. 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;
3. Qhov kev tiv thaiv corrosion ntawm cov hlau tso rau hauv yog txiav txim siab los ntawm kev pom zoo ob zaug ntawm kev muab khoom thiab kev thov.
