Chithunzi Chodziwika cha AWS E9015-B9 Chosavala Choteteza Kuweta kwa Arc Chosagwira Ntchito ndi Ndodo Yonyowa Ma Electrodes Filler Metal
  • AWS E9015-B9 Chosavala Chosagwiritsa Ntchito Arc Welding Rod Stick Welding Electrodes Filler Metal

AWS E9015-B9 Chosavala Chosagwiritsa Ntchito Arc Welding Rod Stick Welding Electrodes Filler Metal

Kufotokozera Kwachidule:

R717 (AWS E9015-B9) ndi electrode yachitsulo yosatentha yokhala ndi chofunda chochepa cha sodium chokhala ndi 9% Cr - 1% Mo-V-Nb.

AWS A5.5 E9015-B9

Kufotokozera: R717 ndi electrode yachitsulo yosatentha yokhala ndi chofunda chochepa cha sodium chokhala ndi 9% Cr - 1% Mo-V-Nb. Gwiritsani ntchito DCEP (electrode yamagetsi yolunjika) ndipo ikhoza kulumikizidwa m'malo onse. Chifukwa cha kuwonjezera pang'ono kwa Nb ndi V, chitsulo chosungidwacho chimakhala ndi kukana kutentha kwambiri.

 

Kugwiritsa Ntchito: Amagwiritsidwa ntchito powotcherera machubu otenthedwa kwambiri ndi mitu ya ma boiler otentha kwambiri komanso opanikizika kwambiri, monga A213-T91/A335-P1 (T/P91), A387Cr, 91 ndi nyumba zina zachitsulo zosatentha.
