Alloy 20 Flanges / UNS N08020 / DIN 2.4660

Among the most common alloys, Alloy 20 contains nickel and low carbon, making it an austenitic niobium-stabilized alloy. There are several elements which will be included in the chemical composition of Alloy 20 Flanges, which consists mainly of nickel, chromium, and iron with some additional elements like molybdenum and copper as well. Even in harsh chemical environments, Alloy 20 Flanges are known for their excellent corrosion resistance. ASTM B462 Uns N08020 pipe flanges are one of the most durable materials available at present, and their excellent mechanical properties make them a great choice for use in an environment that contains citric acid, phosphoric acid, sulfuric acid, and chlorides. The ASTM B462 material is known for its good mechanical properties, even at elevated temperatures.

Blind flanges ASTM B462 UNS N08020 are designed to be used without a bore at the center of the flange.

In the oil and gas industry, these flanges are used mostly to blank the flow in the system. They are frequently used in high pressure and temperature systems. A DIN 2.4660 Weld Neck Flange is distinguished by its long tapered hub that allows them to provide better stability to the piping equipment in high pressure and temperature systems. UNS N08020 Slip on Flanges are slid onto pipes and can be easily welded on their interior or exterior using fillet welding techniques. They can be used for repeated bending conditions. UNS N08020 Slip on Flanges are suitable for use in repeated bending conditions. It is not uncommon to see these flanges in the oil and gas industry because they are reliable and affordable. It has the same strength as a slip on flange and is preferred for setups where there are low pressures and temperatures. The 20cb3 Alloy 20 Socket Weld Flanges are commonly seen in pipes with smaller bore sizes.
