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.
Duplex 2205
1.4462
The most widely used duplex (austenitic-ferritic) stainless steel. Balanced 50/50 microstructure provides twice the yield strength of 304/316L with superior chloride and stress corrosion resistance. Used in oil & gas, chemical processing, marine, and pulp & paper industries.
