Alloy 20 flanges are a highly engineered grade of corrosion-resistant material specially designed for corrosive environments. These flanges provide superior resistance to general and localized corrosion, pitting, crevice corrosion, stress cracking, and many other forms of chemical attack. Alloy 20 is an austenitic stainless steel alloy comprising copper, nickel, and chromium materials that provide excellent resistance to chloride ion stress corrosion cracking. In addition, it has superior resistance to sulfuric acid and nitric acid.
Table of Content
These flanges are ideal for use in extreme temperature applications such as those found in petrochemical plants and the food processing industry where they are often used as a primary source of protection against aggressive chemicals such as sulfuric acid. They also offer excellent performance in acidic or alkaline environments, making them suitable for a wide range of applications. Due to their outstanding resistance to corrosion, Alloy 20 flanges are widely used in the chemical and petrochemical industries where they provide protection against aggressive chemicals such as sulfuric acid. Additionally, they can be used in high-pressure piping systems where they offer superior performance over traditional materials.
Alloy 20 flanges are available from a variety of manufacturers in various sizes and configurations, making them an ideal choice for any application requiring reliable corrosion resistance and durability. They are typically made from carbon steel with additions of molybdenum and copper which increases the alloy’s strength and corrosion-resistance properties.
