NC1250 Incoloy 800H (Alloy 800H, UNS N08810) Flange

Incoloy 800H (Alloy 800H, UNS N08810) Flange Description:

Incoloy alloy is a range of superalloys produced by Special Metals Corporation. They are nickel-iron-chromium alloys that are used for applications that require high corrosion-resistant and high-temperature strength. Incoloy alloys are quite similar to Inconel alloys but their different composition makes some distinctions in their applications.
Incoloy 800H is an iron-nickel-chromium alloy having the same basic composition as Incoloy 800, with significantly higher creep-rupture strength. The higher strength results from close control of carbon, aluminum, and titanium contents in conjunction with a high temp anneal. The 800H modification was to control carbon (0.05 to 0.10%) and grain size (>ASTM 5) to optimize stress rupture properties. Incoloy 800H has further modifications to the combined titanium and aluminum levels (0.85 to 1.2%) to ensure optimum high-temperature properties. The alloy is dual-certified and combines the properties of both forms.
