Material 1.4571

Stainless steel

Grade 1.4571 is an austenitic titanium stabilized stainless steel. 1.4571/316Ti got a good corrosion resistance as well as good mechanical properties. This steel grade is still often being used in Germany.Internationally 1.4404/316L is offten being used instead since itts corrosion resistance is the same but 1.4404 is way simpler to process.
