Stainless steel 316Ti

Fusion welding performance for 316 stainless steel is excellent both with and without fillers. Recommended filler rods and electrodes for  Stainless steel 316 and 316L are the same as the base metal, 316 and 316L respectively. Heavy welded sections may require post-weld annealing. Grade 316Ti may be used as an alternative to Stainless steel 316 in heavy section welds.

Oxyacetylene welding has not been found to be successful for joining of  Stainless steel 316.

316Ti

Another variation of 316 is available. This variation is 316Ti. Stainless steel 316Ti contains a small amount of titanium. Titanium content is typically only around 0.5%. The titanium atoms stabilise the structure of the 316 at temperatures over 800°C. This prevents carbide precipitation from 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. 316Ti retains physical and mechanical properties similar to standard grades of 316.

Applications of Stainless steel 316

Initially developed for use in paper mills  Stainless steel 316 is now typically used in:

• Food processing equipment
• Brewery equipment
• Chemical and petrochemical equipment
• Laboratory benches & equipment
• Coastal architectural panelling
• Coastal balustrading
• Boat fittings
• Chemical transportation containers
• Heat exchangers
• Mining screens
