Sharaxaad Gaaban:

Tuubooyinka Birta Aan Lahayn ee UNS S31254. UNS S31254 waa bir aan lahayn oo aad u austenitic ah oo leh heer sare oo molybdenum iyo nitrogen ah, taasoo bixisa iska caabin sare oo ku wajahan daloolinta iyo daxalka daloolinta iyo sidoo kale xoog sare marka la barbar dhigo birta caadiga ah ee aan lahayn ee austenitic sida 316L. UNS S31254 waa heer austenitic ah kaas oo ku darista chromium, molybdenum iyo nitrogen ay bixiyaan iska caabin sare oo ku wajahan godka biyaha badda. Dahaarkani wuxuu leeyahay celcelis ahaan Lambarka Isku-dhafka ah ee Iska-caabbinta Godka (‚PREN' = Cr+3.3Mo+16N) oo ah 43.8. Tijaabadu waxay muujinayaan iska caabin sare oo ku wajahan weerarka daloolinta-daxalka ee biyaha badda iyo in la xoojiyo dildilaaca daxalka ee sodium chloride kulul oo xooggan. Marka la barbardhigo birta CrNiMo 17 12 2.5, waxay muujinaysaa iska caabin daxalka oo ka sarreysa asiidhyo badan oo isku mid ah xooggeedana waa qiyaastii 50% ka sarreeya. Alxan wanaagsan oo la isticmaalayo waxyaabaha la isticmaalo ee Ni-Cr-Mo. Daminta daminta iyo muddooyinka gaaban ee u dhexeeya 600-1000°C waxay ka hortagtaa horumarka suurtagalka ah ee marxaladda sigma ee ba'an, taas oo laga yaabo inay burburiso oo ay wiiqto iska caabbinta daxalka.
