301 vs X6CrNiTi18-10: 49% composition overlap. Significantly different materials serving different application areas.
301 vs X6CrNiTi18-10
Side-by-side chemical composition and mechanical property comparison.
Overview
301
1.4310
Austenitic stainless steel with the highest work-hardening rate of all 300-series grades. Lower Cr and Ni (17/7 vs 18/9 for 304) makes it metastable — cold working induces martensite transformation for extreme strength (UTS >1300 MPa in full-hard temper). THE stainless spring steel. Used for stainless springs, washers, clips, structural components requiring high strength + corrosion resistance, and railway car bodies.
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).
