About Alloy 800
What is Alloy 800?
Alloy 800 also referred to as the UNS N08800/W.Nr. 1.4876 alloy.
It is the nickel-iron-chromium alloy with additions of molybdenum, copper, nitrogen and silicon.
Alloy 800 is used for heat-treating equipment such as baskets, trays, and fixtures.
In chemical and petrochemical processing, the 800 alloy is used for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required.
In the production of paper pulp, digester-liquor heaters are often made of alloy 800.
In petroleum processing, the alloy is used for heat exchangers that air cool the process stream.
The standard forms in which this alloy is available are round, flats, forging stock, tube, plate, sheet, wire and strip.
