Side-by-side chemical composition and mechanical property comparison.
Overview
304 / X5CrNi18-10
1.4301
The world's most widely used stainless steel — the original 18/8 austenitic. Good corrosion resistance in atmospheric, organic, and inorganic environments. Excellent formability and weldability. Not recommended for chloride-rich or marine environments (use 316L). Used in food processing, kitchen equipment, architecture, tanks, and general engineering.
X2CrNiMoN22-5-3
1.4462
The most widely used duplex stainless steel worldwide (SAF 2205 / UNS S31803/S32205). Austenitic-ferritic microstructure provides ~2× yield strength of 304/316 (≥450 MPa) with excellent resistance to stress corrosion cracking, pitting (PREN 33-38), and intergranular corrosion. Service temperature -50°C to 300°C. Used for oil & gas production tubing, chemical processing vessels, desalination plants, pulp & paper digesters, heat exchangers, and bridge structures. Weldable with ER2209 filler.
