316T​ Stainless Steel Flanges in Various Industries with Material for Secure Connections

Crafted from 316Ti stabilized stainless steel (UNS S31635), these high-performance flanges are engineered to excel in aggressive environments where standard 316/316L steels may fail. With added titanium (Ti) to prevent carbide precipitation, 316Ti delivers superior resistance to intergranular corrosion, pitting, and high-temperature oxidation, making it ideal for chemical processing, marine engineering, power plants, and exhaust systems.

Key Advantages

✅ Unmatched Corrosion Resistance:

• Titanium Stabilization: Eliminates sensitization risks in welded joints, ensuring durability in chloride-rich media (seawater, brine, acids) and sulfur-containing atmospheres.

• PREN ≥27: Superior pitting resistance compared to 316L, perfect for coastal plants, desalination units, and offshore platforms.

✅ High-Temperature Stability:

• Retains strength and oxidation resistance up to 800°C (1472°F), ideal for heat exchangers, boiler components, and automotive exhaust manifolds.

• Resists scaling in cyclic thermal environments, reducing maintenance costs.

✅ Robust Mechanical Performance:

• High Tensile Strength (≥530 MPa) and creep resistance for high-pressure systems (Class 150 to 2500) and vibration-prone applications.

• Excellent fatigue strength for pipelines, pump housings, and valve assemblies.

✅ Global Compliance & Traceability:

• Manufactured to ASTM A182, ASME B16.5, EN 1092-1, and PED 2014/68/EU standards.

• Full MTC 3.1 material certification, ISO 9001/14001 compliance, and PMI (Positive Material Identification) testing.

✅ Cost-Efficient Lifespan:

• Outperforms 316L in harsh conditions, reducing downtime and replacement frequency.

• Compatible with cryogenic (-196°C/-321°F) to high-heat applications.
