304L vs X2CrNi19-11: 77% composition overlap. Some similarities but notable differences in alloying elements.
304L vs X2CrNi19-11
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.
X2CrNi19-11
1.4306
Low-carbon 18/10 austenitic stainless — AISI 304L. C max 0.030% prevents sensitization after welding without stabilizing elements. THE welding-grade 304. Slightly higher Ni (10-12.5%) than 1.4301 (304) for better austenite stability. Used for welded vessels, piping, food equipment, and any 304 application requiring post-weld corrosion resistance without solution annealing.
