Product Overview – ASTM A312 TP316Ti Seamless Pipes
ASTM A312 TP316Ti is a titanium-stabilized version of SS 316 stainless steel. The addition of titanium prevents chromium carbide precipitation during welding and prolonged exposure to elevated temperatures.
SS 316Ti seamless pipes combine corrosion resistance of 316 with improved stability at high temperatures, making them suitable for heat exchangers, pressure vessels, and chemical processing systems.
Seamless construction ensures high pressure handling capability and uniform mechanical properties.
