Nickel thiabNickel Alloy Vuam Electrode
Ni307-4
GB/T ENi6093
AWS A5.11 ENiCrFe-4
Kev piav qhia: Ni307-4 yog ib lub electrode uas siv nickel nrog cov txheej sodium hydrogen tsawg. Siv DCEP (direct current electrode)zoo). Nws muaj kev ua tau zoo heev nrog kev sib txuas ruaj khov arc, tsawg dua spatter, yooj yim tshem tawm slag,
thiab zoo nkauj weld.
Daim Ntawv Thov: Nws yog siv rau kev vuam ntawm cov hlau nickel-chromium-hlau, xws li Ni600, Ni800 / 800H thiab cov superalloys zoo sib xws lossis nickel-based nrog qhov kub ua haujlwm ntawm 900 ° C. Nws kuj tseem siv tau rau cov hlau kub qis uas muaj Ni3% ~ 9%, xws li ASTM A333, A334, A353, A522, Kev vuam ntawm A553 kuj tseem siv tau rau kev vuam hlau sib txawv ntawm Mo400, Ni825, stainless hlau thiab hlau alloy qis.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Fe | Si | Ni | Cr | Mo | Nb + Ta | S | P |
| ≤0.20 | 1.0 ~ 5.0 | ≤12.0 | ≤1.0 | ≥60.0 | 13.0 ~ 17.0 | 1.0 ~ 3.5 | 1.0 ~ 3.5 | ≤0.015 | ≤0.020 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Lub zog tawm los Mpa | Kev ntev % |
| Tau lees paub | ≥650 | ≥360 | ≥18 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 2.5 | 3.2 | 4.0 |
| Vuam tam sim no (Ib) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 300 ℃ ua ntej vuam ua haujlwm;
2. Ua ntej vuam, yuav tsum ntxuav cov xeb, roj, dej, thiab cov av qias neeg ntawm cov khoom vuam. Sim siv lub arc luv luv los vuam.
