Incoloy 800 wire mesh Screen is a solid solution strengthened alloy of nickel, chromium and iron with small additions of aluminum and titanium.
Incoloy 800 wire mesh/Screen is widely used in equipment that must have high strength and resistance to oxidation, carburization and other harmful effects of high temperature exposure. Incoloy 800H or 800HT are used for service requiring optimum creep and rupture properties. The high contents of nickel and chromium in the alloys also give good corrosion resistance.
Mesh: 0.5-250 mesh/Inch Thickness: Min0.05mm
What are the characteristics of Incoloy 800H/HT Mesh?
1. High temperature strength
2. High creep rupture strength
3. Resistant to oxidation and carburization in high temperature environments
4. Good corrosion resistance in many acidic environments
5. Good resistance to many sulfur-containing atmospheres
Oxidation Resistance of Incoloy 800 Wire Mesh/ Screen:
The chromium and nickel contents of the alloy give excellent oxidation resistance, good resistance to carburization and resistance to sulphidation at low concentrations of oxidizing and reducing sulphur. The alloy also has reasonable resistance to nitridation in cracked ammonia, but falls short of the resistance of Inconel 600 wire.
Corrosion Resistance of Incoloy 800 Wire Mesh/ Screen:
Incoloy 800/800H/800HT wire is generally free from both chloride stress corrosion cracking and inter granular corrosion caused by sensitization. The alloy can be used in sea water. Incoloy 800/800H/800HT has resistance to acids similar to austenitic stainless steels. It has excellent resistance to both oxidizing and non-oxidizing salts, except for halide salts, where pitting may occur.
Typical Applications of Incoloy 800 Wire Mesh/ Screen :
1.Thermal processing equipment in industrial applications, such as baskets, trays, and fixtures.
2.In chemical or petrochemical processing it is used for heat exchangers and piping systems in nitric acid media, especially where resistance to chloride stress corrosion cracking is required.
3.In nuclear power plants, it is used for steam-generator tubing.
4.In petroleum processing, the alloy is used for heat exchangers that air-cool the process stream.
5.The alloy is often used in domestic appliances for sheathing of electric heating elements. In the production of paper pulp, digester liquid heaters are often made of alloy 800.
