UNS N08811 - EN/DIN 1.4876
UNS N08811 is a Nickel Chrome Iron Alloy with the same composition as UNS N08800, but with significantly higher creep rupture strength, which is a result of the control of the carbon, aluminium and titanium content. Compared to UNS N08800 it is also corrosion resistant in many aqueous environments.
TPS Technitube Roehrenwerke GmbH supplies UNS N08811 in a big variety of forms incl.:
Seamless Tubes & Pipes
Welded Tubes and Pipes
Buttweld Fittings
Forged Fittings
Flanges and Forgings
Plates, Sheets and Bars
Mechanical values
