Nqe lus piav qhia: W606Fe yog cov hlau tsis tshua muaj hluav taws xob nrog cov hmoov hlau thiab cov txheej txheem hydrogen potassium tsawg.Nws tuaj yeem siv rau txhua txoj haujlwm vuam nrog AC thiab DC.Cov hlau deposited muaj kev cuam tshuam zoo toughness ntawm -60 ° C.
Daim ntawv thov: Siv rau vuam tsis tshua muaj hlau xws li 2.5Ni.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Ni | S | P |
| ≤0.12 | ≤1.25 | ≤ 0.80 | 2.00-2.75 Nws | ≤ 0.020 | ≤ 0.025 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj | Tensile zog Mpa | Yield zog Mpa | Elongation % | Tus nqi cuam tshuam (J) -60 ℃ |
| lav | ≥540 | ≥440 | ≥17 | ≥ 27 |
Diffusion hydrogen ntsiab lus ntawm deposited hlau: ≤6.0mL / 100g (glycerin method) los yog ≤10mL / 100g (mercury los yog gas chromatography method)
X-ray kuaj: qib kuv
Pom zoo tam sim no:
| (mm) Qws txoj kab uas hla | 3.2 | 4.0 | 5.0 |
| (A) Vuam tam sim no | 90 ~ 120 hli | 140 ~ 180 ib | 180 ~ 210 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.
