INCOLOY 800/N08800 NICKEL ALLOY PIPE/TUBE

Incoloy 800 is a solid solution strengthened alloy of nickel, chromium, and iron with small additions of aluminum and titanium. ASTM B163 B407 ASME SB163 SB407 N08800 Incoloy 800 Seamless Tubing is particularly useful for high-temperature equipment in the petrochemical industry because the alloy doesn\'t form the embrittling sigma phase after long time of exposure at 1200°F (649°C). Excellent resistance to chloride stress-corrosion cracking is another important feature of alloy 800 pipe, alloy 800 tube.
