316Ti vs 409 / X2CrTi12
Side-by-side chemical composition and mechanical property comparison.
Overview
316Ti
1.4571
Titanium-stabilized austenitic stainless steel with molybdenum. Stabilization prevents sensitization during prolonged high-temperature exposure. Very popular in Germany for chemical, pharmaceutical, and food processing. Being replaced internationally by 316L (1.4404) for most applications.
409 / X2CrTi12
1.4512
Lowest-chromium ferritic stainless steel with Ti stabilization. Developed specifically for automotive exhaust systems as a cost-effective alternative to austenitic grades. Good oxidation resistance to ~800°C. Used for exhaust manifolds, catalytic converters, mufflers, and heat shields.
