Key Features of Alloy 20 Plate
- Corrosion Resistance: Both alloys have better resistance to chemicals and acids but 904L is better in dealing with sulfuric acid whereas Alloy 20 Plate is resistant to both phosphoric and sulfuric acids and hence more versatile for different industries.
- Mechanical Properties: 904L possesses improved low-temperature toughness, but Alloy 20 Plate exhibits good resistance to stress corrosion cracking, particularly in highly acidic conditions.
- Cost-Effective: Alloy 20 Plate is comparatively affordable than 904L without compromising on the integral characteristics like durability and resistance to corrosion, thus proving to be a cost-effective option for most applications.
Compositions and Properties of Alloy 20 Plate
The chemical composition of Alloy 20 Plate is specially designed to achieve maximum strength and resistance in severe environments.Nickel (Ni) – 32% is the main component that offers resistance to chloride stress corrosion cracking, whereas Chromium (Cr) – 20% increases its oxidation resistance. The inclusion of Molybdenum (Mo) – 3% provides better resistance to pitting and crevice corrosion, making Alloy 20 Plate suitable for environments that are exposed to aggressive chemicals such as sulfuric acid.
The high Iron content balances the alloy’s cost while maintaining its mechanical properties and corrosion resistance. Its regulated Carbon content makes the alloy stable at high temperatures without being affected by carbide precipitation. The balanced content gives Alloy 20 Plate higher strength and endurance, guaranteeing long lasting service life in severe applications like chemical processing, food processing and pharmaceutical manufacturing.
