304L vs X2CrNiMoN22-5-3: 60% composition overlap. Moderate differences, generally not direct substitutes.
304L vs X2CrNiMoN22-5-3
Side-by-side chemical composition and mechanical property comparison.
Overview
304L
1.4307
Low-carbon version of 304. Maximum 0.030% C prevents sensitization during welding — no post-weld heat treatment needed. The standard choice for welded structures in food, chemical, and pharmaceutical industries. Often dual-certified with 1.4301.
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.
