Material Characteristics
UNS S31635 (316Ti) is a titanium-stabilized version of 316 molybdenum-bearing austenitic stainless steel. The 316 alloys offer superior resistance to general corrosion and pitting/crevice corrosion compared to conventional chromium-nickel austenitic stainless steels such as 304. They also provide higher creep, stress-rupture, and tensile strength at elevated temperatures.
Titanium additions stabilize the structure against chromium carbide precipitation, significantly reducing susceptibility to sensitization. This allows the alloy to be used for extended periods at elevated temperatures without compromising corrosion resistance. 316Ti provides equivalent corrosion resistance to sensitization as the low carbon version 316L.
