HastelloyC Alloy waa Ni-Cr-Molybdenum-Tungsten aluminium ah oo bixiya caabbinta daxalka guud ahaan ka wanaagsan kuwa kale ee jira ee Ni-Cr-Molybdenum-Hastelloy C276,C4 iyo 625.
Alloys Hastelloy C waxay leeyihiin iska caabin heer sare ah oo ay u leeyihiin godadka, daxalka dillaaca iyo dildilaaca daxalka walwalka.
Waxay leedahay iska caabin heer sare ah oo ay u leedahay inay oxidizing warbaahinta biyaha, oo ay ku jiraan koloriin qoyan, nitric acid ama isku-dar ah asiidh oksaydhing ah oo ay ku jiraan ion chloride.
Isla mar ahaantaana, Hastelloy C Alloys waxay sidoo kale leeyihiin awood ku habboon oo ay iskaga caabiyaan hoos u dhigista iyo jawiga oksaydhka ee la kulma inta lagu jiro habka.
Kala duwanaanshahan, waxaa loo isticmaali karaa degaannada dhibka leh, ama warshadaha ujeedooyin kala duwan oo wax soo saar ah.
Daawaha Hastelloy C waxay leedahay iska caabin gaar ah oo ku wajahan bey'ado kala duwan oo kiimiko ah, oo ay ku jiraan walxo oksaydhiyeyaal xoog leh, sida ferric chloride, chloride copper, chlorine, thermal pollution solution (organic ama inorganic), formic acid, acetic acid, acetic anhydride, biyaha badda iyo xalalka milixda.
Hastelloy C alloy waxay awood u leedahay inay iska caabiso samaynta roobabka xadka hadhuudhka ee aagga kulaylka alxanka ee saameeya, taas oo ka dhigaysa mid ku habboon noocyo badan oo codsiyada habka kiimikaad ee gobolka alxanka.
