Tsawg Alloy Steel Vuam Electrode
J506NiMA, J507NiMA
GB/T E5016-G E5015-G
AWS E7018-G E7015-G
Nqe lus piav qhia: J506NiMA thiab J507NiMA yog cov dej noo-absorbing ultra-low hydrogen-coated low-alloy steel electrodes.Cov hlau deposited muaj zoo heev plasticity, tsawg-kub toughness thiab tawg tsis kam, thiab yuav welded nyob rau hauv txhua txoj hauj lwm.Cov txheej yog resistant rau noo noo nqus.Tom qab cov electrode tau ci ntawm 400 ° C x 1h thiab nres hauv ib puag ncig nrog cov av noo txheeb ze ≥ 80% rau 4 teev, cov dej noo ntawm cov txheej tseem ua tau raws li qhov yuav tsum tau siv.
Daim ntawv thov: Nws yog siv rau kev vuam ntawm cov roj platforms, nkoj, cov hlab ntsha siab, thiab lwm yam qauv ua los ntawmcarbon steel thiab low alloy steel.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Ni | S | P | |
| lav | ≤0.12 | ≥1.00 Nws | ≤0.50 | ≤ 0.60 | ≤ 0.035 | ≤ 0.040 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % | Tus nqi cuam tshuam (J) -46 ℃ |
| lav | ≥490 | ≥390 | ≥ 22 | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤5.0mL / 100g (gas chromatography los yog mercury method)
Cov dej noo ntawm electrode txheej: ≤0.30%
X-ray kuaj: qib kuv
Pom zoo tam sim no:
| Qws txoj kab uas hla | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no | 60 ~ 90 | 90 ~ 120 hli | 140 ~ 180 ib | 170-210 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm 350 ~ 400 ℃ ua ntej vuam ua haujlwm;
2. Nws yog ib qho tseem ceeb los ntxuav cov xeb, roj nplai, dej, thiab impurities ntawm vuam qhov chaw ua ntej vuam;
3. Siv luv arc ua haujlwm thaum vuam.Txoj kev nqaim welding yog tsim nyog.
