SUS316Ti Austenitic Stainless Steel – Titanium-Stabilized High-Temp 316 Alloy

Product Introduction

SUS316Ti is a titanium-stabilized austenitic stainless steel, derived from SUS316 to enhance high-temperature stability and post-weld corrosion resistance. Containing 0.10-0.20% titanium, this grade forms stable carbides that prevent chromium depletion, eliminating sensitization during welding and prolonged heating. It retains the full molybdenum-enhanced chloride corrosion resistance of SUS316, with improved creep resistance at temperatures up to 800°C. Unlike standard SUS316, SUS316Ti maintains structural and corrosion integrity in thermal-cycling environments, making it ideal for high-heat corrosive applications.
