Side-by-side chemical composition and mechanical property comparison.
Overview
316 / X5CrNiMo17-12-2
1.4401
Standard-carbon austenitic stainless steel with molybdenum. Higher C than 316L (max 0.07% vs 0.03%) giving slightly higher strength. Same corrosion resistance as 316L. Used where welding is not required or post-weld solution annealing is possible.
X6CrNiMoTi17-12-2
1.4571
Titanium-stabilized austenitic Cr-Ni-Mo steel — AISI 316Ti. THE German standard industrial stainless (known as "V4A"). Ti prevents Cr-carbide precipitation at 450-850°C giving intergranular corrosion resistance after welding. Better high-temp stability than 316L (up to 550°C). PREN 23-27. Used extensively in chemical/pharmaceutical plants, pressure vessels, food processing, apparatus construction, and shipbuilding.
