Molybdenum ndi Chromium Molybdenum Heat Resistant Steel Welding Electrode
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Kufotokozera: R407 ndi pearlitic zitsulo zosagwira kutentha kwa electrode yokhala ndi chitsulo chochepa cha hydrogen sodium chokhala ndi 2.5% Cr - 1% Mo. Gwiritsani ntchito DCEP (mwachindunji panopa electrode positive) ndipo akhoza welded mu malo onse.Kuwotcherera kuyenera kutenthedwa mpaka 200 ~ 300 ° C musanayambe kuwotcherera.
Ntchito: Ntchito kuwotcherera mkulu-kutentha ndi mkulu-anzanu mapaipi ndi ntchito kutentha m'munsimu 550 ° C, kupanga mankhwala makina, mafuta akulimbana zida, etc.
Chemical zikuchokera weld zitsulo (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
Zimango za weld zitsulo:
| Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % | Mtengo (J) Normal Temp. |
| Zotsimikizika | ≥590 | ≥490 | ≥15 | ≥47 |
| Kuyesedwa | 600 ~ 680 | ≥500 | 18-21 |
Kuphatikizika kwa haidrojeni muzitsulo zoyikidwa: ≤4.0mL/100g (njira ya glycerin)
Kuwunika kwa X-ray: Ndimapanga
Zomwe tikulimbikitsidwa:
| Ndodo diameter (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 60-90 | 90-120 | 140 ~ 180 | 170 ~ 210 |
Zindikirani:
1. Elekitirodi ayenera kuphika kwa ola 1 pa 350 ℃ pamaso kuwotcherera ntchito;
2. Ndikofunikira kuyeretsa dzimbiri, sikelo yamafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.
