Stainless Steel 316Ti Seamless Tubes Manufacturer in India
What Are Stainless Steel 316Ti Seamless Tubes?
Stainless Steel 316Ti Seamless Tubes are titanium-stabilized austenitic stainless steel tubes developed for applications requiring reliable corrosion resistance and structural stability during prolonged exposure to elevated temperatures. Grade 316Ti is identified by UNS S31635 and is based on the 316 stainless steel composition with titanium added to improve resistance to sensitization.
The titanium stabilization of 316Ti helps prevent chromium carbide precipitation when the material is exposed to elevated temperatures. This characteristic allows Stainless Steel 316Ti Seamless Tubes to maintain their corrosion-resistant properties in applications involving extended thermal exposure. The presence of molybdenum also contributes to improved resistance against pitting and crevice corrosion in chloride-containing environments.
For industrial requirements, Stainless Steel 316Ti Seamless Tubes can be supplied according to applicable ASTM and ASME specifications. Common requirements include ASTM A213 for seamless alloy-steel boiler, superheater and heat-exchanger tubes and other applicable standards based on the tube's intended service. Dimensions can be supplied according to outside diameter, wall thickness, schedule, length and finish requirements.
These tubes are suitable for heat exchangers, chemical processing equipment, petrochemical systems, refinery equipment, power generation plants, high-temperature process lines, marine equipment and pharmaceutical machinery. The combination of titanium stabilization, molybdenum-bearing chemistry and austenitic structure makes 316Ti useful where both corrosion resistance and elevated-temperature stability are important.
