Njengoba kunikezwe lesi sigaba esiphathelene nensimbi engagqwali, yiluphi uchungechunge olune-nickel eningi?
Context:Kunezigaba ezimbili zensimbi engagqwali ye-austenitic. Izinsimbi ezingenasici zochungechunge lwe-300 zithola ukwakheka kwazo kwe-austenitic ngokuyinhloko ngokungezwa kwe-nickel ngenkathi izinsimbi ezingenasici zochungechunge lwe-200 zithatha indawo ye-nickel nge-manganese ne-nitrogen, yize kusekhona okuqukethwe okuncane kwe-nickel.
Uchungechunge lwama-300 luqukethe i-nickel eningi.
