What is Incoloy 825 alloy bar？

Incoloy 825 alloy bar is a high-performance material primarily composed of nickel, iron, chromium, and molybdenum, providing exceptional resistance to a wide range of corrosive environments and elevated temperatures. Known for its outstanding resistance to sulfuric acid, chloride stress corrosion cracking, and oxidation, Incoloy 825 is widely used in industries that require materials to perform reliably in harsh conditions, such as chemical processing, wastewater treatment, marine applications, and pickling lines.

• Exceptional Corrosion Resistance
  Incoloy 825 alloy bar excels in environments where resistance to sulfuric acid and other aggressive chemicals is required. Its high nickel content ensures superior resistance to chloride-induced stress corrosion cracking, while the addition of molybdenum provides resistance to both pitting and crevice corrosion, making it a preferred choice for industries handling corrosive materials.

• High-Temperature Strength
  Incoloy 825 alloy bars maintain their strength and structural integrity even in high-temperature applications, with excellent resistance to oxidation and scaling. The alloy can withstand continuous service at temperatures up to 815°C (1500°F) and short-term exposure to even higher temperatures, making it suitable for various high-temperature industrial applications.

• Versatile Fabrication
  Incoloy 825 bars are easily fabricated using common machining, welding, and forming techniques. Their weldability and ease of fabrication make them ideal for complex components that require high strength, corrosion resistance, and thermal stability.

• Resistant to Stress Corrosion Cracking
  Incoloy 825 offers excellent resistance to stress corrosion cracking, especially in chloride-rich environments. This makes it ideal for applications in the oil and gas industry, chemical processing, and wastewater treatment, where other alloys may be prone to failure.
