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.:

Mechanical values

Annealing condition:

Chemical Analysis

 

 

C = 0,05% – 0,10% Ti = 0,15% – 0,60%
AL + Ti = 0,30% – 1,20% Al = 0,15% -0,60%
Ni = 30% – 35% Cr = 19% – 23%
Fe = bal
