316Ti vs X2CrNiN18-7: 68% composition overlap. Moderate differences, generally not direct substitutes.
316Ti vs X2CrNiN18-7
Side-by-side chemical composition and mechanical property comparison.
Overview
316Ti
1.4571
Titanium-stabilized austenitic stainless steel with molybdenum. Stabilization prevents sensitization during prolonged high-temperature exposure. Very popular in Germany for chemical, pharmaceutical, and food processing. Being replaced internationally by 316L (1.4404) for most applications.
X2CrNiN18-7
1.4318
Nitrogen-alloyed work-hardening austenitic — AISI 301LN. Lower Ni (6-8%) than 304 makes it metastable: cold work transforms austenite to martensite → UTS up to 1400 MPa in full-hard condition. N addition compensates low C for corrosion and strength. Used for rail car bodies, springs, structural parts requiring high strength-to-weight ratio, and architectural cladding.
