Nickel thiab Nickel Alloy Vuam Electrode
Ib 307-7
GB/T ENi6152
AWS A5.11 ENiCrFe-7
Nqe lus piav qhia: Ni307-7 yog nickel-based electrode nrog qis-hydrogen sodium txheej.Siv DCEP (direct tam sim no electrodezoo).Nws muaj kev ua haujlwm zoo heev nrog kev ruaj khov arc combustion, tsawg spatter, yooj yim tshem tawm slag,thiab zoo nkauj weld.Cov hlau deposited muaj cov khoom ruaj khov thiab zoo corrosion kuj nyob rau hauvhigh-temperature oxidizing thiab sulfur-muaj cua.
Daim ntawv thov: Siv nyob rau hauv nuclear engineering, sulfuric acid, nitric acid thiab hydrogen fluorine manufacturing khoom, xws li npib tsib xee 690 alloy, ASTM B166, B167, b168, thiab lwm yam., kuj yuav siv tau rau vuam nickel-chromium hlau thiab stainless hlau thiab surfacing corrosion. -resistant txheej ntawm steel.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Fe | Si | Ni | Cr |
| ≤ 0.05 | ≤5.0 | 7.0 ~ 12.0 Nws | ≤ 0.8 | ≥50.0 | 28.0-31.5 Nws |
| Cu | Mo | Nb | S | P | Lwm yam |
| ≤0.5 | ≤0.5 | 1.0 ~ 2.5 hli | ≤ 0.015 | ≤ 0.020 | ≤0.5 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % |
| lav | ≥550 | ≥360 | ≥ 27 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.5 | 3.2 | 4.0 |
| Vuam tam sim no (A) | 60 ~ 90 | 80 ~ 110 ib | 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;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam.Sim siv luv luv arc rau vuam.
