AISI 316Ti (UNS S31635) ist der titanium-stabilized version von 316, mit titanium added bei 5×(C+N) minimum zu prevent chromium carbide precipitation während welding oder elevated-temperature service. While 316L achieves der gleich goal durch niedrig carbon content, 316Ti offers two advantages: superior hoch-temperature strength und creep widerstand von der titanium carbonitrides, und der ability zu sein used bei temperatures wo 316L's niedrig-carbon matrix würde lose strength. Norm material für chemical plant pressure vessels operating bei 400-550°C, pulp und paper digester heaters, und aircraft abgas components. Der stabilization auch eliminates der risk von intergranular corrosion in der HAZ von heavy-abschnitt welds wo 316L könnte sensitize despite niedrig carbon.

Frequently Asked Questions
316Ti vs 316L—welche zu choose?
Für ambient und moderate-temperature (unter 400°C) applications, 316L ist mehr widely stocked und mehr economical—der niedrig-carbon approach achieves der gleich weld sensitization widerstand. Choose 316Ti wenn: operating temperature exceeds 400°C continuously, der komponente undergoes repeated welding und stress-relief cycles, oder der application requires guaranteed intergranular corrosion widerstand nach post-weld heat treatment bei sensitization temperatures (450-850°C).
