800H/AT (Incoloy® 800) is an austenitic heat resistant alloy designed for high temperature structural applications. The strength of 800H/AT is achieved by controlled levels of carbon, aluminum and titanium along with a 2100°F minimum anneal to achieve a grain size of ASTM 5 or coarser. Alloy 800 H/HT® Corrosion MaterialsAlloy 800H/800HT® is frequently used in applications that involve long-term exposure to elevated temperatures where resistance to oxidation, carburization and other types of elevated temperature corrosion is required. Heat treatment and power generation are
Alloys 800H (UNS N08810) and 800HT (UNS N08811) are dual-certifiable Nickel-Iron-Chromium materials that resist oxidation, carburization and other high temperature corrosion. The chemical composition of the two alloys are identical to Alloy 800 (UNS N08800), with the exception of the higher level of carbon present in both grades (0.050.10 High-Performance Alloys for Resistance to Aqueous Nickel and the INCONEL®, INCOLOY® and MONEL® Corrosion-Resistant Alloys A world leader in the development and production of high-perform-ance, mainly nickel-based, alloys,Special Metals has manufacturing facilities in the USA and Europe, and sales and service locations in North America,Europe and Asia. Serving markets ranging from Incoloy 800 Pipe Fittings, Alloy 800H Butt weld Fittings Incoloy 800 / 800H / 800HT Pipe Fittings have exceptional resistance to seawater even at reducing environments. These pipe fittings are stabilized against sensitization, also it resists intergranular corrosion. This grade has a sufficient amount of nickel to make resistance to
Incoloy 800 Plates/ Sheets are incoloy-chromium alloy with an addition of aluminum for outstanding resistance to oxidation and other forms of high temperature corrosion. These incoloy 800/800h/800ht sheets (UNS N08800) are used for Heat treating muffles and retorts, Catalyst support grids in nitric acid production, Radiant tubes, Steam super-heater tube supports, and more. incoloy Alloy 800 Plates are Incoloy 800H Alloy 800H Alloy 800HT Incoloy 800HT Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 percent aluminum and titanium in alloy 800HT. Incoloy 800H Alloy 800H Alloy 800HT Incoloy 800HT Today, most suppliers, including Mega Mex, only carry the dual certified 800H/HT alloy. Incoloy 800 is primarily 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
The INCOLOY® 800 series of alloys, invented by the Special Metals Corporation Group of Companies, is the result of years of monitoring and maintaining the ultimate chemical properties for high-temperature strength and resistance to oxidation, carburization and other types of high-temperature corrosion. Each one a refinement of the one before, these alloys have set the industry standard in Incoloy Alloy 800 / 800H / 800HT chemical composition and The Incoloy 800HT contains 0.5% titanium in the composition. As a result, the Alloy 800HT has higher creep resistance and strength than the 800H. The Incoloy 800 chemical composition makes it oxidation resistant and carburization resistant under high temperatures. Incoloy Alloy 800 / 800H / 800HT chemical composition and The Incoloy 800HT contains 0.5% titanium in the composition. As a result, the Alloy 800HT has higher creep resistance and strength than the 800H. The Incoloy 800 chemical composition makes it oxidation resistant and carburization resistant under high temperatures.
lncoloy® 800 is a nickel-iron-chromium alloy designed with good strength and to resist oxidation and carburization at elevated temperatures. The high nickel content (30% Min.) makes the alloy highly resistant both to chloride stress-corrosion cracking and to Incoloy, Incoloy Alloys - MEGA MEXAlloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternatives to the various Incoloy brand alloys. The corrosion-resistant superalloys are widely used in extreme environments where tremendous heat and corrosion resistance is paramount to the integrity of the end product.
