Ko te Alloy31 tetahi ahua o te koranu rino nichrome molybdenum azotic, ko te mahi kei waenga i te super austenite kowiri tira me te koranu turanga nika.
1.te mahi
2.High tensile te kaha, te kaha o te manawanui, te kaha ngokingoki me te kaha pakaru i te 700 ℃.
3.High inoxidability at1000 ℃.
4.Steady mahi miihini i roto i te iti o te pāmahana.
Ko te huinga Alloy 31 e pa ana ki te matū me te ahumahi matū hinu, te kaupapa taiao me te hinu, hau, me era atu mara ahumahi.
