Alloy 321 (UNS S32100) jẹ titanium diduro austenitic alagbara, irin pẹlu ti o dara gbogbo ipata resistance. O ni atako to dara julọ si ipata intergranular lẹhin ifihan si awọn iwọn otutu ni iwọn ojoriro carbide chromium ti 800 – 1500°F (427 – 816°C). Awọn alloy koju ifoyina si 1500 ° F (816 ° C) ati pe o ni awọn ohun elo ti nrakò ati wahala ju awọn alloys 304 ati 304L. O tun ni lile iwọn otutu kekere ti o dara.

Alloy 321H (UNS S 32109) jẹ erogba ti o ga julọ (0.04 – 0.10) ẹya alloy. O jẹ idagbasoke fun imudara resistance ti nrakò ati fun agbara ti o ga julọ ni awọn iwọn otutu ju 1000oF (537°C). Ni ọpọlọpọ awọn iṣẹlẹ, akoonu erogba ti awo naa jẹ ki iwe-ẹri meji ṣiṣẹ.

Alloy 321 ko le ṣe lile nipasẹ itọju ooru, nikan nipasẹ iṣẹ tutu. O le ni irọrun weled ati ni ilọsiwaju nipasẹ awọn iṣe iṣelọpọ ile itaja boṣewa.
