SUS316Ti Stainless Steel: Titanium-Stabilized 316 Variant

316L is considered to be more resistant to oxidation than type 316, especially in warm marine environments. Once again, its low levels of carbon protect it against carbon precipitation. The metal also shows resistance in extremely low temperatures, even down to cryogenic levels. In regards to heat, 316L shows better resistance to creep, stress to rupture and overall strength than other stainless steel grades.

Many of the same work practices effective on type 316 may also be employed on 316L, including weldability and work hardening through cold working. In addition, 316 does not require post-work annealing to maximize its corrosion resistance, however annealing may be utilized in certain situations.

Stainless Steel 316Ti is referred to as the stabilized grade of the 316 types, and also one of the two 316 stainless steels that is recommended for higher 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 elevated 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, pitting from chloride solutions and increased strength when placed in high temperature environments. 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.

316Ti is commonly utilized in heat exchangers, paper mill equipment, and architectural components in marine environments.
