316Ti Stainless Steel

316Ti stainless steel is a titanium-stabilized version of 316 stainless steel, designed to maintain excellent corrosion resistance while providing superior strength and stability at elevated temperatures. The addition of titanium prevents chromium carbide precipitation during welding, reducing the risk of intergranular corrosion and maintaining long-term durability. 316Ti is ideal for applications in chemical processing, power generation, petrochemical plants, marine environments, and high-temperature equipment. It is supplied in wire rod form under standards such as ASTM A276/A479. 316Ti stainless steel is specified over standard 316 in petrochemical and power-generation piping that operates continuously at elevated temperatures, where titanium stabilization prevents sensitization during long-term service.

Features

Material Advantages

Titanium Stabilization

Titanium helps bind carbon and reduce chromium carbide precipitation during welding or elevated-temperature exposure.

Elevated-Temperature Stability

Selected for service where molybdenum-enhanced corrosion resistance and improved thermal stability are both required.

Intergranular Corrosion Resistance

Stabilized chemistry helps protect against intergranular corrosion in welded or thermally exposed components.

Chemical Process Equipment Service

Used for equipment requiring corrosion resistance, weldability and thermal exposure capability in chemical and petrochemical environments.
