The 316Ti Stainless Steel also known as 1.4571 Stainless Steel with UNS S31635 is an austenitic stainless steel that gives the ideal corrosion resistance and has very low carbon content. Stainless Steel 316Ti (1.4571) is majorly used in thermal and welding processes. In the annealed condition SS 316Ti (AISI 316Ti) is nonmagnetic and gets magnetic when welded. In the pulp and paper mills, SUS316Ti shows good resistance due to the excess acidic surrounding.
316Ti Stainless Steel Properties
316Ti Stainless Steel has special properties typical to the product. The following sums up the qualities of EN 1.4571 Stainless Steel.
- 316ti has good corrosion resistance.
- In acidic chloride environments, 316 Ti has greater corrosion.
- The resistance is high with molybdenum alloy percentage.
- AISI 316Ti is resistant to sulphuric acid at around 120 degrees Fahrenheit.
- SS316Ti has good formability and weldability.
316Ti Stainless Steel Applications
316Ti Stainless Steel (S31635) is used in flue gas desulfurization systems and is also a regular component in petrochemical industries. The chemical process vessels and pulp and paper industry also use SS 316Ti. Stainless Steel 316Ti (SUS 316Ti) is also used in condensers in power generation.
SS 316Ti Resistance and Processing
Corrosion Resistance of 316Ti
Stainless Steel 316ti (1.4571) has excellent corrosion resistance when exposed to a range of corrosive environments and media. AISI 316Ti (UNS S31635) is usually regarded as “marine grade” stainless steel but is not resistant to warm sea water. Warm chloride environments can cause pitting and crevice corrosion. 316Ti Stainless Steel is also subject to stress corrosion cracking above around 60°C.
316Ti has good resistance to oxidation in intermittent service to 870°C and in continuous service to 925°C. However, continuous use at 425-860°C is not recommended if corrosion resistance in water is required. In this instance, 316L is recommended due to its resistance to carbide precipitation. Where high strength is required at temperatures above 500°C, grade 316H is recommended.
316ti stainless steel (UNS S31635) has good machinability. Machining can be enhanced using the following rules:
- 316Ti SS Cutting edges must be kept sharp. Dull edges cause excess work hardening.
- SS 316Ti Cuts should be light but deep enough to prevent work hardening by riding on the surface of the material.
- 316ti Chip breakers should be employed to assist in ensuring swarf remains clear of the work.
- SUS 316Ti has Low thermal conductivity of austenitic alloys results in heat concentrating at the cutting edges. This means coolants and lubricants are necessary and must be used in large quantities.
Fusion welding performance for 316Ti steel (1.4571) is excellent both with and without fillers. Recommended filler rods and electrodes for 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 316 in heavy section welds. Oxyacetylene welding has not been found to be successful for joining of 316ti stainless steel.
All common hot working processes can be performed on 316Ti stainless steel (UNS S31635). Hot working should be avoided below 927°C. The ideal temperature range for hot working is 1149-1260°C. Post-work annealing is recommended to ensure optimum corrosion resistance.
Stainless Steel 316Ti is readily brake or roll formed into a variety of parts. AISI 316Ti (SUS316Ti) is also suited to stamping, heading and drawing but post work annealing is recommended to relieve internal stresses. Cold working will increase both strength and hardness of 316ti stainless steel.
Fabrication of all stainless steels should be done only with tools dedicated to stainless steel materials. Tooling and work surfaces must be thoroughly cleaned before use. These precautions are necessary to avoid cross contamination of stainless steel by easily corroded metals that may discolor the surface of the fabricated product.
