316Ti vs X12CrNi25-21
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.
X12CrNi25-21
1.4845
Heat-resistant 25Cr-21Ni austenitic stainless — AISI 310S (low-C variant). Oxidation resistance to 1050°C continuous, 1150°C intermittent. Higher Cr+Ni than 304/316 = much better high-temperature scaling resistance. Used for furnace parts, radiant tubes, heat treatment fixtures, kiln linings, and thermocouple protection tubes. Also used in petrochemical cracker tubes.
