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.
X6Cr17
1.4016
THE standard ferritic stainless steel — 16-18% Cr, no Ni. Non-hardenable, magnetic, lower cost than austenitic grades. Good corrosion resistance for indoor/mild environments. Used for kitchen sinks, automotive trim, washing machine drums, architectural panels, and catering equipment. Not suitable for welding thick sections (grain coarsening). AISI 430.
