Item Code: 800
Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys having high resistance to carburization and oxidation in high-temperature exposure and with good strength. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 % aluminum and titanium in alloy 800HT.
Incoloy 800 was the first of these alloys and it was slightly modified into Incoloy 800H. The modification made was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. Incoloy 800HT has more modifications to the combined aluminum and titanium levels (.85-1.20%) to ensure optimum high temperature properties.
The nickel alloy is dual certified (800H/HT) and combines the properties of both forms. Incoloy 800H/HT alloy was actually meant for high-temperature structural applications. These alloys are resistant to embrittlement from precipitation of sigma phase and chloride stress-corrosion cracking due to the nickel content. The corrosion resistance is quite high.
In the solution annealed condition, alloys 800H and 800HT have excellent creep and stress rupture properties. The dual certified 800H/HT alloy is commonly available also with Mega Mex.
Incoloy 800 is mainly used in applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.
Incoloy 800HT will not become embrittled even after long periods of usage in the 1200-1600° F range where many stainless steels become brittle.
Superior cold forming properties associated with the nickel-chromium alloys are exhibited with 800HT. When cold forms extensively, the grain size produces a visibly undulated surface called “orange peel”. Incoloy 800HT can be welded by the common techniques used on stainless steels.Chemical CompositionAlloy 800 (UNS N08800) Chemical Composition, %

Item Code: 825
Incoloy 825 is highly resistant to corrosion. It has a high nickel content, sufficient to resist chloride ion stress corrosion cracking, and a very stable austenite structure. The levels of molybdenum and copper enable the alloy to resist reducing agents and acids. Chromium gives resistance to oxidising conditions, such as nitric acid solutions, nitrates and oxidising salts. The alloy is titanium stabilised to resist pitting and intergranular attack after fabrication, particularly welding, which includes heating in the critical sensitisation temperature range (650°C – 760°C).
Alloy 825 offers exceptional resistance to corrosion by sulphuric and phosphoric acids and is often the most cost effective alloy in sulphuric acid service.
Incoloy 825 is approved for pressure vessel operating temperatures up to 525°C (AS1210, AS4041), 538°C (ASME Boiler & Pressure Vessel Code, Sections I, III, VIII, IX, Cases 1936, N-188). Brittle phases may form in alloy 825 at temperatures above ~ 540°C, so it is not normally used at these temperatures, where creep-rupture properties would be design factors.Applications of Incoloy 825
Typical Applications of Incoloy Alloy 825 include:
• Sulphuric acid piping and vessels
• Phosphoric acid evaporators
• Pickling tank heaters, pickling tanks and equipment
