316Ti Stainless Steel: Titanium-Stabilized for High Heat

 

What's unique about 316Ti's chemical composition?​

It contains 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and 0.10-0.20% titanium. Titanium binds with carbon, preventing chromium carbide formation at high temps, which enhances corrosion resistance in welded areas.​

 

How does 316Ti perform in high-temperature settings?​

316Ti retains strength up to 800°C, outperforming 316 in prolonged heat exposure. It resists creep and oxidation, making it ideal for heat exchangers and furnace components in chemical plants.​

 

What are its corrosion resistance properties?​

Similar to 316, it excels in chloride-rich environments like seawater and chemical solutions. The titanium stabilization ensures post-weld corrosion resistance, critical for welded structures in harsh settings.​

 

How does 316Ti compare to 316L in fabrication?​

316Ti is slightly harder to form than 316L but offers better high-temperature strength. It welds well with standard techniques, with no need for post-weld heat treatment thanks to titanium stabilization.​

 

What are 316Ti's typical applications?​

Commonly used in heat exchangers, pressure vessels, and chemical reactors. It's also found in offshore oil equipment and desalination plants where heat and corrosion resistance are vital.
