316Ti is a variant of 316 stainless steel that is alloyed with titanium. The addition of titanium to the steel gives it improved resistance to corrosion, particularly in environments with high temperatures and high concentrations of chlorides. The titanium content of 316Ti is typically around 0.5%.

316Ti is often used in the construction of heat exchangers, furnace parts, and chemical and petrochemical equipment. It is also used in the food and pharmaceutical industries, as well as in marine environments. The high resistance to corrosion makes it suitable for use in applications where the steel will be exposed to saltwater or other corrosive substances.

The mechanical properties of 316Ti are similar to those of standard 316 stainless steel, with a slightly higher yield strength and a lower elongation at break. The material is also non-magnetic and has a good weldability and formability.

316Ti also has a higher resistance to intergranular corrosion than standard 316 stainless steel, making it less susceptible to sensitization, which is a phenomenon that occurs when the steel is exposed to high temperatures. This can cause the steel to become brittle and susceptible to cracking.

When it comes to welding 316Ti, it is best to use a filler metal with a higher titanium content than the base metal. This will help to prevent the formation of carbides in the weld zone and ensure that the weld has the same corrosion resistance as the base metal.

Overall, 316Ti is a versatile stainless steel that is well suited for a wide range of applications in harsh environments. Its high resistance to corrosion, combined with its good mechanical properties, make it an ideal choice for a wide range of industries.
