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.
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.
