1. What is 316Ti Stainless Steel?

316Ti stainless steel is an austenitic stainless steel alloy, a variant of 316 stainless steel, enhanced with titanium (typically 0.4–0.7%) to prevent intergranular corrosion during welding or exposure to high temperatures (425–815°C). This titanium stabilization makes 316Ti stainless steel ideal for applications requiring durability in aggressive environments, such as chemical processing, marine, and power generation. Gangsteel’s 316Ti stainless steel is engineered to meet stringent standards like JIS G4304 SUS316Ti and ISO TR15510, ensuring reliability for critical projects.
