Tsawg Alloy Steel Vuam Electrode
j556f ua
GB/T E5518-G
AWS E8018-G
Nqe lus piav qhia: J556fe yog cov hlau tsis tshua muaj hlau electrode nrog hlau hmoov thiab tsis tshua muaj hydrogen txheej.AC thiab DC tuaj yeem siv tau, thiab tuaj yeem txuas rau txhua txoj haujlwm.
Daim ntawv thov: Siv rau vuam nruab nrab carbon steel thiab qis alloy steel qauv xws li Q390.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | S | P |
| ≤ 0.12 | ≥1.00 Nws | ≤ 0.80 | ≤ 0.035 | ≤ 0.035 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % | Tus nqi cuam tshuam (J) -40 ℃ |
| lav | ≥540 | ≥440 | ≥17 | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤10.0mL / 100g (mercury los yog gas chromatography method)
X-ray kuaj: qib kuv
Pom zoo tam sim no:
| (mm) Qws txoj kab uas hla | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Vuam tam sim no | 70 ~ 110 ib | 100 ~ 140 hli | 140-170 ib | 190-240 ib |
Daim ntawv ceeb toom:
1. Cov electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ 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.
