W.Nr.1.4876 Nickel base alloy steel

W.Nr.1.4876 is a nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature exposure.W.Nr.1.4876/HT alloy was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties.

W.Nr.1.4876 Nickel alloy similar material are : UNS N08810,Incoloy 800H,X5 NiCrAlTi 31-20

W.Nr.1.4876 Nickel alloy usually used in the following industries :
Ethylene furnace quench boilers
Hydrocarbon cracking
Valves, fittings and other components exposed to corrosive attack from 1100-1800° F
Industrial furnaces
Heat-treating equipment
Chemical and petrochemical processing
Super-heater and re-heaters in power plants
Pressure vessels
Heat exchangers
