What is 316Ti Stainless Steel?

Stainless Steel 316Ti (UNS S31635) is a titanium-stabilized version of Type 316 and also one of the two 316 austenitic stainless steels that is recommended for elevated temperature situations. This grade contains a small amount—typically only 0.5%—of titanium. While it still possesses many of the characteristics of other 316 grades, the addition of titanium allows 316Ti to be protected from precipitation at high temperatures, even with prolonged exposure. 316Ti also contains an addition of molybdenum in its composition. Like in other 316 grades, the molybdenum serves as increased protection against corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304, pitting from chloride solutions and offer higher creep, stress-rupture and tensile strength at elevated temperature. However, its high temperature resistance is also compounded by its titanium content, which allows 316Ti to be immune to precipitation at these temperatures. Additionally, the metal shows resistance to acids, such as sulfuric acids, hydrochloric acids, and acid sulfates.

It is also known as DIN/EN designation No. 1.4571. Type 316 stainless steel can be susceptible to sensitization ñ the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500 °F (425 to 815 °C) ñ which can result in rapid corrosion. Reduced carbon Type 316L is resistant to sensitization; however, extended exposures in this temperature range will eventually result in sensitization of even the low carbon grade. Resistance to sensitization is achieved in Type 316Ti with titanium additions to stabilize the structure against chromium carbide precipitation, which is the source of sensitization. The titanium atoms stabilise the structure of the 316 at temperatures over 800°C. This prevents carbide precipitation at the grain boundaries and protects the metal from corrosion. The main advantage of 316Ti is that it can be held at higher temperatures for a longer period without sensitisation (precipitation) occurring. Thus, the alloy can be used for extended periods at elevated temperatures without compromising its corrosion resistance. 316Ti retains physical and mechanical properties similar to standard grades of 316. The austenitic structure of 316 stainless steel gives excellent toughness, even at cryogenic temperatures.

Austenitic stainless steels can be welded together using many different welding processes. Some are more preferred for welding than others, such as 304, 308, 316, 321, and 347 which are all austenitic grades that are weldable.
