FAQ's
What is Austenitic Stainless Steel 316Ti and how is it different from 316 stainless steel?
Austenitic Stainless Steel 316Ti is a titanium stabilized version of SS 316, designed to resist intergranular corrosion caused by carbide precipitation during welding. While both alloys offer excellent corrosion resistance in chloride and acidic environments, 316Ti provides better high temperature strength and stability, making it ideal for continuous service up to 800°C.
What are the main properties of Stainless Steel 316Ti?
SS 316Ti is known for:
- Superior resistance to intergranular corrosion due to titanium stabilization.
- Excellent performance in chloride and acidic environments.
- High strength retention at elevated temperatures.
- Good weldability and fabrication properties.
- Suitability for hygienic and high temperature applications.
Where is Stainless Steel 316Ti commonly used?
316Ti stainless steel is widely used in industries such as:
- Chemical & petrochemical plants (vessels, piping, heat exchangers).
- Power generation (boiler tubes, superheaters, turbines).
- Marine environments (pumps, valves, and seawater exposed components).
- Pharmaceutical & food processing (sanitary fittings and hygienic equipment).
- Automotive & aerospace (exhaust systems and high-temperature engine parts).
Why is Stainless Steel 316Ti preferred for high-temperature applications?
The titanium content in SS 316Ti prevents carbide precipitation during welding and prolonged heating, which enhances resistance to intergranular corrosion. This stabilization allows it to maintain mechanical strength and corrosion resistance even at temperatures up to 800°C, making it ideal for power plants, heat exchangers, and chemical processing equipment.
