Product Description

Product Description

 

ALLOY 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 hightemperature applications requiring optimum creep and rupture properties. Alloy 800 was introduced to the market in the 1950s to fill the need for a heat- and corrosion-resistant alloy with a relatively low nickel content since nickel was, at the time, designated a "strategic" metal. Over the past forty years it has been widely used for its strength at high temperatures and its ability to resist oxidation, carburization, and other types of high-temperature corrosion. Applications include furnace components and equipment, petrochemical furnace cracker tubes, pigtails and headers, and sheathing for electrical heating elements.

 

FEATURES

N08800 has good rupture and creep strength and  excellent resistance to oxidation, carburization and  sulfidation at temperatures up to 816ºC. It also resists general corrosion by many aqueous media. For applications requiring higher stress rupture and creep properties, especially at temperatures above 816ºC, N08810 and N08811are recommended. N08800 is readily formed, welded and machined.
 

APPLICATIONS

Chemical and petrochemical process piping, heat exchangers, furnace components, carburizing equipment, heating-element sheathing, and nuclear power steam-generator tubing.
