In austenitic stainless steels containing more carbon, titanium is utilized as a stabilizing element to prevent the production of chromium carbides. It can increase the ability of higher carbon grade welds to resist water corrosion. Much as 321 is connected to 304, 316Ti Stainless Steel is a derivation of 316. While 316Ti is uncommon in the petrochemical and aerospace industries, 321 is the titanium stabilized variant of 304.
316Ti is essentially nonexistent in North American stock and typically needs a mill manufacturing run. 316Ti is extremely well-liked in Europe for historical reasons. European nations primarily maintain the grade's existence as the chosen material in many standards.

Properties of 316TI Stainless Steel Grade

Since a long time ago, 316/316L has become the material of choice for chemical processes and aqueous corrosion applications in different countries. The minimum yield stress for the three variations, 316, 316L, and 316Ti, in any of the fundamental EN standards, EN 10088-2 (General application), EN 10088-4 (Structural application), and 10028-7 are the same. And notwithstanding the possibility of a larger carbon content (Pressure vessel application). The YS is specified as a minimum of 220 MPa (32 KSI) for plate in all three Euro norms. Although the YS for 316L is slightly lower in ASTM standards than for 316 and 316Ti (30 KSI), there is practically no difference because almost all 316L is dual certified as 316.

Advantages of SS 316TI Grade

There is no benefit to utilizing 316Ti Stainless Steel over 316H for high-temperature service (over 1000° F). A stabilized grade may be required in selected circumstances where equipment may experience both elevated temperature service and sporadic aqueous corrosion problems. Catalytic cracking and hydrogenation are two petroleum refining processes that may run into these circumstances. The corrosion resistance of 321 is sufficient in these environments. It is more typical to take into consideration alloys like Alloy 20 or 825 if the predicted aqueous corrosion is too severe for 321.
