Grade 316Ti or UNS S31635 is an austenitic titanium stabilised version of grade 316 stainless steel. Compared to the conventionally used chromium-nickel austenitic stainless steels like alloy 304, grade 316 Ti alloys are more resistant to general corrosion as well as to pitting and crevice corrosion. The Stainless Steel 316Ti Flanges also offers higher creep, stress-rupture and tensile strength properties. Although its tensile strength properties are unaffected to elevated temperature, the stainless steel grade 316 H could be susceptible to sensitisation, the formation of grain boundary chromium carbides especially at a temperature ranging between 900 to 1500°F. Thus resulting in intergranular corrosion. However, this problem could be solved by using the ASTM A182 316Ti Blind Flange. Grade 316Ti is an alloy which has the ability to resist sensitisation. This, in turn, can be achieved by alloying the metal with titanium. Titanium, when added to stainless steel grades acts as a stabilizing agent.

ASTM A182 316Ti Blind Flange
ASME SA182 F316Ti Slip on Flanges
Titanium added in the UNS S31635 Slip On Flange combines with carbon to form titanium carbides. The newly formed titanium carbide is not only quite stable but it is hard to dissolve in steel. Thereby effectively minimizing the occurrence of intergranular corrosion in SS 316Ti Blind Flange. Hence, the 316Ti Stainless Steel Flanges could be used for an extended period of time at an elevated temperature without compromising its mechanical and corrosion resistance properties. 316Ti stainless steel has corrosion resistance properties equivalent to sensitisation as the low carbon version 316L.
