Nominal muaj pes tsawg leeg (feem pua ntawm qhov hnyav) yog 60Ni-22Cr-9Mo-Fe-3.5Nb + Ta, nickel-chrome-molybdenum alloy electrode.
Vim muaj cov ntsiab lus siab ntawm cov hlau, nws tuaj yeem hloov mus rau qhov kub thiab txias ntawm qhov kub tsawg mus rau 540 ℃.
Nws muaj zog thiab corrosion kuj ntawm chav tsev kub thiab kub, nrog rau pitting corrosion kuj, tawg corrosion thiab kev nyuaj siab corrosion nyob rau hauv polysulfurous acidic media.
ruaj khov arc, zoo nkauj sib sau, me ntsis txaws, yooj yim slag tshem tawm, zoo porosity tsis kam, txhua yam khoom ntawm molten hlau yog ruaj khov.
