Nickel alloys have a high resistance to corrosion at temperatures of about 540o C. In return for the use of the commercial nickel at elevated temperatures, it is essential to consider both its limits.
200 nickel alloy comprising the minor content of about 0.10% carbon, is subjected to embrittlement of carbon or graphite intergranular precipitated when kept at a temperature of 425oC to 760oC or 800oF 1400oF for long periods of time. You can buy high performance alloy materials from the companies such as https://rjtechnical.com/.
Nickel alloy 201 at low cost carbon nickel, the maximum carbon content of 0.01 to 0.02%, are not prone to this embrittlement providing carbonaceous materials are not in contact with it.
In applications where compounds of sulfur atoms are available, or where high temperature resistance is required, Inconel 600 is quickly replaced by Nickel 200 or Nickel 201.
A too high temperature for the proper performance of metals, sometimes used in fused silica, silica brick lining or graphite.
However the family of chromium-nickel stainless steels appears to offer superior corrosion resistance to the limit temperature 400 ° C to 425oC or 750oF or 800F, a case of stress corrosion of stainless steel 347 was found in the wetsuit gas in the presence of HCL.
It is ensured that the chromium-nickel-iron alloys are proven by successful applications in the components of muriatic furnaces of a cast alloy, the chemical composition: Ni-37% Cr 27%, Mo 3%, Cu 2%, 0.25% and C rem. The iron.
