Titanium-Stabilised Alloy for High-Temp Exhaust Architecture Specifically engineered for thermal-critical exhaust manifold fabrication, this Schedule 10 weld-on fitting is formed from AISI 321 austenitic stainless steel, a titanium-stabilised variant designed to mitigate carbide precipitation during high-temp service. Unlike 304 or 316, 321 maintains structural integrity under prolonged exposure to elevated exhaust gas temperatures, making it the alloy of choice for turbocharged, track-duty, and endurance builds.
• Alloy Composition: Fe–Cr–Ni base with Ti stabilisation • Thermal Stability: Withstands >850°C without loss of grain boundary cohesion • Weldability: Schedule 10 wall thickness ideal for TIG fusion with minimal distortion • Corrosion Profile: Superior resistance to intergranular attack post-weld • Use Case: Primary tubes, turbo collectors, and high-velocity exhaust transitions
This is not a cosmetic stainless. It’s a function-first metallurgy solution for fabricators who demand longevity, weld consistency, and thermal resilience in every pass.
