Stainless Steel 316Ti Flanges Manufacturer
Stainless Steel 316Ti Flanges are titanium stabilized flanges, made from the austenitic stainless steel alloy UNS S31635. Even at high temperatures, these flanges retain their superior mechanical qualities and provide strong resistance against intergranular corrosion. Midland Alloys Inc. is a reputable manufacturer and global supplier of Stainless Steel 316Ti Flanges. We offer a wide range of types, including weld neck, blind, slip-on, and RTJ flanges. Our flanges are manufactured in accordance with ASTM A182 / ASME SA182 standards and meet high-performance pressure and structural integrity criteria. With chemical balance enhanced with titanium, chromium, nickel, and molybdenum, and surface treatments such as rough-turned, machined, or mirror-polished. In corrosive and hot conditions SS 316Ti flanges guarantee durability and strength.
Key Benefits of Stainless Steel 316Ti Flanges
SS 316Ti flanges deliver long-term reliability across industries due to their enhanced corrosion resistance, thermal strength, and easy weldability.
- Corrosion Resistance – Titanium stabilization prevents intergranular corrosion during welding or heat exposure.
- High Temperature Stability – Performs effectively in temperatures exceeding 500°C without compromising structural integrity.
- Weldability: By avoiding carbide precipitation during welding, titanium ensures stronger, cleaner connections.
- Strength and Durability: These flanges function effectively under load and pressure, because of their strong mechanical construction.
- High Strength: Even under the most severe service conditions, it retains its tensile and yield strength.

Stainless Steel 316Ti Flanges vs ASTM A350 LF2 Flanges
Stainless Steel 316Ti flanges offer superior corrosion and heat resistance due to their titanium content, making them ideal for aggressive chemical and high-temperature environments. In contrast, ASTM A350 LF2 flanges are low-temperature carbon steel flanges with moderate corrosion resistance and are generally preferred for cryogenic applications. While 316Ti provides austenitic properties with enhanced weldability, LF2 is favored in systems requiring toughness at sub-zero temperatures but lacks the chemical resistance of 316Ti. Both meet different industry needs based on environmental demands and application temperature ranges.

Applications of Stainless Steel 316Ti Flanges
Steel 316Ti flanges play a key role in high-stress industrial systems. They are utilized in heat exchangers, pipelines and processing columns in the petrochemical and oil and gas industries because of their resilience to corrosive environments and changing pressure. The chemical processing industry relies on them for handling acids, chlorides, and solvents. In power generation, especially in boilers and turbine connections, their high-temperature tolerance ensures safety and performance. Marine engineering uses these flanges for pump systems and underwater pipelines where saltwater corrosion is a challenge.

FAQ
Yes, 316Ti flanges can be welded without post-weld heat treatment, due to titanium stabilisation that prevents carbide precipitation and intergranular corrosion.
316Ti provides superior corrosion resistance in mildly acidic to moderately aggressive environments, including diluted sulfuric and hydrochloric acids.
For SS 316Ti, TIG (GTAW) and MIG (GMAW) welding techniques are often used. The titanium content of the alloy contribute to stability when welding.
No, When annealed, SS 316Ti flanges are typically non-magnetic. However, slight magnetism may occur after cold working.
