In the industrial landscape, the need for materials that can endure extreme conditions while maintaining their integrity is paramount. Our Incoloy 201/Incoloy 200 capillary tubes are engineered to meet these exacting requirements. These tubes are a cornerstone in various industrial applications, offering a unique blend of properties that make them stand out in the market.
Incoloy 201
Incoloy 201 is a nickel - based alloy. Nickel forms the base of this alloy, providing it with excellent resistance to corrosion in a wide range of environments. It also contributes to the alloy's high - temperature stability. The addition of chromium in Incoloy 201 is crucial. Chromium reacts with oxygen in the air to form a thin, adherent chromium oxide layer on the surface of the alloy. This passive layer acts as a barrier, preventing further oxidation and corrosion. Additionally, small amounts of other elements are added to enhance specific properties. For example, certain trace elements may improve the alloy's formability and weldability.
Incoloy 200
Incoloy 200 is also a nickel - rich alloy. Its composition is optimized to provide a balance between corrosion resistance and mechanical strength. The high nickel content gives it good resistance to reducing environments, such as those containing hydrogen sulfide. Similar to Incoloy 201, it contains chromium, which aids in the formation of the protective oxide layer. Incoloy 200 may also have small amounts of other alloying elements like iron and manganese, which can influence its physical and mechanical properties.
