316Ti vs X2CrNiMo17-12-2: 89% composition overlap. Some similarities but notable differences in alloying elements.
316Ti vs X2CrNiMo17-12-2
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.
X2CrNiMo17-12-2
1.4404
Low-carbon molybdenum-bearing austenitic stainless steel, widely known as AISI 316L. The Mo addition (2–2.5%) significantly improves resistance to pitting and crevice corrosion compared to 1.4301 (304). Low carbon content (max 0.03%) ensures resistance to intergranular corrosion after welding without post-weld heat treatment. Standard grade for pharmaceutical, petrochemical, chemical and marine applications. PREN 23–29.
