- Titanium (Ti): 0.5-0.8%
- Copper (Cu): 0.5% (maximum)
- Manganese (Mn): 0.5% (maximum)
- Silicon (Si): 0.5% (maximum)
- Phosphorus (P): 0.02% (maximum)
- Sulfur (S): 0.01% (maximum)
- Carbon (C): 0.05% (maximum)
Production standards:
The production standards of INCOLOY 832 include ASTM B435, UNS N08332, etc.
Corrosion resistance:
INCOLOY 832 has good corrosion resistance and is suitable for various environments with strong corrosive media. It can resist the corrosion of strong acids such as sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, phosphoric acid, and strong alkalis such as chloride, ammonia, and cyanide, and oxidizing media. In addition, INCOLOY 832 is also resistant to corrosive media such as seawater, salt spray and sulfuric acid. Therefore, it is widely used in marine engineering, chemical equipment, oil refining and chlor-alkali production and other fields.
High temperature performance:
INCOLOY 832 has good high temperature resistance, and still maintains high strength and toughness at high temperatures. Its maximum service temperature can reach 815°C, so it is widely used in equipment and pipelines under high temperature conditions.
Typical application range:
INCOLOY 832 is widely used in chemical industry, petroleum, electric power, nuclear industry and other fields. It can be used in the manufacture of chemical equipment, oil refining equipment, chlor-alkali production equipment, marine engineering, nuclear industry equipment, heat exchangers, piping systems, etc.
