Bright Surface UNS N08800 ASTM B407 Incoloy 800 Tubing

ASTM B407 ASTM B163 Incoloy 800 909 825 840 tubing

B407 Standard Specification for Nickel-Chromium-Iron Alloy Seamless Pipe and Tube

Most common grades: (800H, 800HT)

The alloy has good corrosion resistance in high temperature steam, including steam air CO2 mixture. In some high temperature and high pressure water medium, its stress corrosion resistance is obviously better than 18-8 stainless steel and inconel600; in H2 + H2S medium, it also has good corrosion resistance, and in alkaline medium containing NaOH, it has good corrosion resistance The stress corrosion resistance is better than that of inconel600 and other high nickel alloys.
