MATERIAL DESCRIPTION
The material 2.4817 is a nickel-chromium-iron alloy with a very limited carbon content. It is the LC variant of the material 2.4816.
The more limited carbon content favours a higher resistance to alkaline solutions contaminated with sulphur and offers a slightly higher temperature resistance.
It should also be noted that the mechanical properties are lower than those of the non-LC variant 2.4816.
AN OVERVIEW OF THE PROPERTIES OF 2.4817:
- Good oxidation resistance
- Good resistance to carburisation and nitriding
- Good resistance to stress corrosion cracking (room and elevated temperatures)
- Good resistance to dry chlorine and hydrogen chloride (up to approx. 500-550 °C)
- Good resistance to acetic, hydrofluoric and fatty acids as well as caustic soda
- Resistance in alkaline solutions contaminated with sulphur
APPLICATIONS
- Industrial furnace construction
- Chemical engineering
- Production of hydrocarbons (chlorinated and fluorinated)
- Production of caustic alkalis (with sulphur compounds)
