Ni327-3
GB/T ENi6625
Sharaxaad: Ni327 -3 waa korantad ku salaysan nikkel oo leh daahan soodhiyam hooseeya.Isticmaal DCEP (electrode toos ah haddatogan).Birta la shubay waxay leedahay caag aad u wanaagsan, adkeyd iyo iska caabin dildilaac ah, waxayna leedahay awood sare iyo iska caabin daxalka oo xoogan heerkulka qolka iyo heerkulka sare.
Codsiga: Waxaa loo isticmaalaa alxanka ee nikkel-chromium-molybdenum alloys, gaar ahaan alxanka iyo dulsaarka ee UNS N06625 alloys iyo noocyada kale ee birta ah iyo birta ka kooban nikkel-chromium-molybdenum, iyo sidoo kale loo isticmaali karaa alxanka Ni9% steel hoostooda. xaaladaha heerkulka hooseeya.

Ogaysiis:
- Korodhka waa in lagu dubaa 1 saac qiyaastii 300 ℃ kahor alxanka.Isku day inaad isticmaasho qaanso gaaban si aad u alxankato;
- Waa lagama maarmaan in la nadiifiyo miridhku, saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.
3. Isku day inaad isticmaasho tamar khadka yar marka alxanka, lakabka badan iyo alxanka baasaska badan.
