Inconel 601 Seamless Pipes has excellent resistance to inter-granular corrosion after exposure to temperatures in the chromium carbide precipitation range. Inconel 601 Welded Pipes contains chromium, nickel and a substantial addition of titanium. In Inconel 601 EFW Pipes, the carbon combines preferentially with titanium to form harmless titanium carbide, leaving the chromium in solution to maintain full corrosion resistance. Inconel 601 ERW Pipes is often used to make radiant super-heaters, boiler tubes, high pressure steam pipes, and general refinery piping. Inconel 601 Round Pipes is the grade of choice for applications in the temperature range of up to about 900 Degree C. Inconel 601 Square Pipes is protected from temperatures ranging from 800 Degree F to 1500 Degree F. Inconel 601 Rectangular Pipes resists oxidation to 1500 Degree F (816 Degree C) and has higher creep and stress rupture properties.
