Nickel thiab Nickel Alloy Vuam Electrode
N327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
Nqe lus piav qhia: Ni327 -6 yog nickel-raws li electrode nrog low-hydrogen sodium txheej.Siv DCEP (direct tam sim no electrodezoo).Cov hlau deposited muaj zoo heev plasticity, toughness thiab tawg kuj.Deposited hlau muaj ib tug linear expansion coefficient zoo ib yam li cov hlau, thiab muaj siab zog thiab muaj zog corrosion kuj nyob rau hauv chav tsev kub thiab kub.
Daim ntawv thov: Nws yog siv rau kev vuam ntawm Ni9% steel, thiab tseem tuaj yeem siv rau vuam ntawm cov hlau tsis sib xws thiab nyuaj-rau-vuam alloys.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤ 0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Lwm yam |
|
| 0.5 ~ 2.0 hli | 1.0 ~ 2.0 hli | 12.0-17.0 Nws | ≤ 0.015 | ≤ 0.020 | ≤0.5 |
|
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
| lav | ≥620 | ≥350 | ≥32 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 |
| Vuam tam sim no (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 300 ℃ ua ntej vuam ua haujlwm.Sim siv luv luv arc rau vuam;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam.
3. Sim siv cov kab me me zog thaum vuam, ntau txheej thiab ntau dhau welding.
