1. What is 316Ti Stainless Steel?

316Ti Stainless Steel (UNS S31635, Werkstoff Nr. 1.4571)is an austenitic stainless steel alloy with added titanium to enhance its resistance to sensitization and intergranular corrosion at elevated temperatures. The "Ti" in 316Ti stands for titanium, which stabilizes the material by forming titanium carbides, preventing chromium depletion during prolonged exposure to high heat (425–815°C or 900–1500°F). This makes 316Ti ideal for high-temperature piping systems in industries like chemical processing, oil and gas, and power generation.

Compared to 316L, 316Ti offers better high-temperature strength and creep resistance due to its titanium content, while maintaining excellent corrosion resistance in chloride-rich environments. It’s a versatile choice for applications requiring durability under thermal stress. Learn more about related grades at Gangsteel Stainless Steel Solutions.

2. Chemical Composition of 316Ti Stainless Steel

The chemical composition of 316Ti stainless steel is designed for corrosion resistance and high-temperature stability, as outlined in ASTM A312 and related standards. Below is the typical composition:

Note: The titanium content, typically at least five times the carbon content, prevents carbide precipitation, enhancing resistance to sensitization during high-temperature exposure. This composition provides superior performance compared to standard 316 stainless steel in corrosive and high-heat environments.
