Incoloy Alloy 800 pipe is an austenitic stainless steel alloy composed of iron, nickel and chromium. It is widely regarded as having excellent high temperature oxidation resistance and corrosion resistance. It is suitable for a variety of extreme environments, such as high temperature and highly corrosive media.
Material composition and basic properties
Chemical composition: Incoloy Alloy 800 is mainly composed of chromium, nickel and iron, of which the nickel content is very high, accounting for about 30%-35%.
Physical properties: The alloy has good thermal conductivity and low thermal expansion coefficient, which makes it stable in temperature-changing environments and not easy to deform.
Mechanical properties and processing characteristics
Strength and ductility: Incoloy Alloy 800 has high tensile strength and good ductility.
Welding performance: Incoloy Alloy 800 has excellent welding performance.
Corrosion resistance and high temperature resistance
Corrosion resistance: Due to its unique chemical composition, Incoloy Alloy 800 shows excellent corrosion resistance to a variety of acids and alkalis, including hydrochloric acid, sulfuric acid, etc. This corrosion resistance makes it an ideal material for handling corrosive media in the chemical and petrochemical industries.
High temperature oxidation resistance: Incoloy Alloy 800 can maintain stable performance at temperatures up to 1150°C, which makes it very suitable for high temperature applications such as heat treatment equipment and furnace structures.
Application areas and cases
Petrochemical industry: In the petrochemical industry, Incoloy Alloy 800 is used to manufacture key components such as heat exchange equipment, boiler feed water heaters, pipelines, containers, towers, tanks, valves, pumps, reactors, etc.
