Nickel na Nickel Alloy Welding Electrode
Ni307-3
GB/T ENi6182
AWS A5.11 ENiCrFe-3
Nkọwa: Ni307-3 bụ anickel-dabere na electrode na obere-hydrogen sodium mkpuchi.Jiri DCEP (ezigbo electrode ugbu a kpọmkwem).Ọ nwere ezigbo mgbape mgbape n'ihi na weld nwere ụfọdụ manganese, niobium, na ihe ndị ọzọ na-eme ka ihe ndị ọzọ na-eme ihe.
Ngwa: Ọ na-eji maka ịgbado ọkụ nkenickel-chromium-iron alloys (dị ka UNS N06600) na nchara nke nchara.Ọnọdụ okpomọkụ na-arụ ọrụ adịghị elu karịa 480 Celsius C, na nkwụsị mgbape dị mma.Kwesịrị ekwesị maka ụgbọ mmiri nrụgide ọkụ atomiki na ịgbado ọkụ tankị kemịkal.
Ngwakọta kemịkalụ nke igwe weld (%):
