304 Stainless Steel vs X6CrNiTi18-10: 69% composition overlap. Moderate differences, generally not direct substitutes.
304 Stainless Steel vs X6CrNiTi18-10
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.
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).
