Datasheet: Stainless Steel 316Ti
Stainless Steel 316Ti
316 Ti has better high temperature strength and mechanical strength than 316L, thanks to the additions of Titanium, which means Stainless Steel 316Ti can be used for extended periods at elevated temperatures without compromising its corrosion resistance.
Stainless Steel 316Ti is also known as AISI 316Ti, Supra316Ti, Nirosta 4571, Polarit 761, and Remanit 4571.
Available in all profile options
