ECoCr-B (Cobalt 12) Cobalt Hardfacing & Wear-resistant Welding Electrode
Alloy Nau'in: A5.13, SOLID SURFACING Electrodes da Welding Sanduna, A5.13
Ana iya la'akari da ECoCr-B Cobalt Alloy 12 a matsayin tsaka-tsakin tsaka-tsaki tsakanin Cobalt Alloy 6 da Cobalt Alloy 1. Ya ƙunshi mafi girma juzu'i na wuya, gaggautsa carbides fiye da Cobalt Alloy 6, kuma ya karu juriya ga ƙananan kusurwa yashwa, abrasion, da kuma mai tsanani. zamiya lalacewa yayin da yake riƙe m tasiri da cavitation juriya.Cobalt Alloy 12 sau da yawa ana amfani da kansa ko kuma yana gudana da Cobalt Alloy 6 ko 1. Mafi girman abun ciki na tungsten yana samar da mafi kyawun kaddarorin zafin jiki idan aka kwatanta da Cobalt Alloy 6, kuma ana iya amfani dashi a yanayin zafi har zuwa kusan 700⁰C.Cobalt Alloy 12 yawanci ana amfani dashi don yankan kayan aikin da ke buƙatar jure wa abrasion, zafi da lalata.
