304 Stainless Steel vs X2CrNi19-11: 69% composition overlap. Moderate differences, generally not direct substitutes.
304 Stainless Steel vs X2CrNi19-11
Side-by-side chemical composition and mechanical property comparison.
Overview
304 Stainless Steel
1.4301
The most widely used austenitic stainless steel. Excellent corrosion resistance, good formability and weldability. Standard choice for food processing, chemical, and architectural applications.
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.
