ASTM B407 UNS N08811 DIN 1.4959 / INCOLOY 800HT SEAMLESS ALLOY STEEL PIPE
Alloy 20 offers outstanding resistance to a wide range of corrosive media, especially sulfuric acid and other aggressive chemicals. This makes it ideal for applications in chemical manufacturing and storage. It also has good tensile strength and yield strength, contributing to its performance under different operating conditions.
Here are some key characteristics of Alloy 20 seamless Pipe:
Chemical Composition: Typically contains nickel (32% min), chromium (19% min), molybdenum (2.5% min), along with small amounts of iron, carbon, manganese, silicon, and sulfur.
Corrosion Resistance: Excellent resistance to sulfuric acid, phosphoric acid, and other harsh environments, making it suitable for chemical processing.
Temperature Range: Maintains strength and stability at high temperatures, often used in environments that experience elevated thermal conditions.
Mechanical Properties: Good mechanical strength and ductility, with yield strength typically around 30,000 psi and tensile strength around 70,000–80,000 psi.
Weldability: Can be easily welded and fabricated, ensuring versatility in various applications.
