What is Incoloy800? Material Chemical composition list Application fields Characteristics
Incoloy800 application areas:
Incoloy 800 (N08800) alloy chemical industry, nuclear generators, nitric acid coolers, acetic anhydride cracking tubes, heat exchange equipment, heat exchange tubes, etc.
GNEE Steel's additional features of Incoloy800:
The alloy has a high chromium content and sufficient nickel content, so it has high high temperature corrosion resistance and is widely used in industry. It has excellent resistance to stress corrosion cracking in chloride, low-concentration NaOH aqueous solutions and high-temperature and high-pressure water, so it is used to manufacture equipment that is resistant to stress corrosion cracking. The corrosion resistance is better than that of general austenitic stainless steel and better than Inconel 600 alloy; in the manufacture of corrosion-resistant stress cracking equipment, it is better than Inconel 600 and Monel 400 alloy.
GNEE Steel's introduction to thermal processing of Incoloy 800 (N08800) alloy:
(1) The temperature range is 1200℃~950℃, and the cooling method is water quenching or rapid air cooling.
(2) In order to obtain the best performance and creep resistance, solution treatment must be carried out after thermal processing.
(3) The material can be directly fed into a furnace that has been heated to 1200°C, kept warm for a sufficient time and then quickly discharged from the furnace for thermal processing within the specified temperature range. When the material temperature drops below the thermal processing temperature, it needs to be reheated.
GNEE Steel's introduction to cold working of Incoloy 800 (N08800) alloy:
(1). The work hardening rate is greater than that of austenitic stainless steel, so processing equipment needs to be selected. Cold-worked materials should be in a solution heat-treated state, and intermediate annealing should be performed when the amount of cold work is large.
(2) If the amount of cold working is greater than 10%, the workpiece needs to be subjected to secondary solution treatment.
GNEE Steel introduces the welding process of Incoloy 800 (N08800) alloy:
Suitable for using any traditional welding process with the same material or other metals, such as tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal pole inert gas shielded welding, melting pole inert gas shielded welding, among which pulse arc welding is the preferred option. If manual arc welding is used, it is recommended to use (Ar+He+H2+CO2) as the shielding gas.
