ʻO ka haku inoa inoa (pakeneka ma ke kaumaha) ʻo 60Ni-22Cr-9Mo-Fe-3.5Nb+Ta, kahi electrode nickel-chrome-molybdenum alloy.
Ma muli o ke kiʻekiʻe o ka alloy, hiki iā ia ke hoʻololi i ka pae wela mai ka haʻahaʻa haʻahaʻa a hiki i 540 ℃.
Loaʻa iā ia ka ikaika kiʻekiʻe a me ke kūpaʻa corrosion ma ka lumi wela a me ka wela kiʻekiʻe, me ka pitting corrosion resistance, crack corrosion a me ke koʻikoʻi corrosion ma polysulfurous acidic media.
Paʻa arc, nani ka hana ʻana, liʻiliʻi liʻiliʻi, maʻalahi ka wehe ʻana i ka slag, kūpaʻa porosity maikaʻi, paʻa nā waiwai mechanical o ka metala hoʻoheheʻe.
