304L vs X6CrNiTi18-10: 65% composition overlap. Moderate differences, generally not direct substitutes.
304L vs X6CrNiTi18-10
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.
X6CrNiTi18-10
1.4541
Titanium-stabilized austenitic stainless — AISI 321. Ti (5×C min) prevents Cr-carbide sensitization during welding or service at 400-800°C. Same approach as Nb-stabilized 347 (1.4550) but with Ti instead. Better creep resistance than 304/304L at elevated temperature. Used for exhaust manifolds, aircraft exhaust systems, expansion bellows, and high-temperature chemical plant (to ~800°C).
