Cr20ni80 NiCr8020 Nicr Alloy Nichrome Waea mo te Huanga Whakawera

Whakaahuatanga Poto:

Ko te rauemi NiCr8020 me te nama rauemi 2.4869 ka whakamahia i roto i te ahua o nga takai, pepa, ngongo me nga waea mo nga waahanga hanga oumu me nga kaiwhakahaere whakamahana. He koranu whakamahana nickel-chromium mo nga pāmahana whakahaere tae atu ki te 1150 °C me te maha o nga taapiri o nga whenua onge mo te kaha ake o te aukati ki te hauhautanga, ina koa me nga mahi whakawhiti auau me nga rereketanga o te pāmahana whanui. Ko te parenga ki te waikura o te hau i te 20 °C he teitei ki te teitei o te pāmahana whakahaere te parenga ki te hau me etahi atu hau e mau ana i te hāora tae atu ki nga hau hauota iti-hauora he tiketike ano, heoi he iti ki te oxidizing me te whakaiti hau kei roto whanariki. He tiketike te ātete ki te carbonizing. Te tono mo nga oumu hiko ahumahi, nga oumu enamelling, nga taputapu o te whare, nga waahi rokiroki mo te po-naianei.
