Alloy 20 is an alloy composed of nickel, chromium, and iron used in various industries. It has great resistance properties to corrosion and acids, making it an ideal material for many applications. Alloy 20 is a highly corrosion-resistant nickel, chromium, and molybdenum alloy. Alloy 20 Sheets offer superior resistance to pitting, crevice corrosion, and stress corrosion cracking. It is also resistant to sulfuric acid up to 98% concentration at room temperature and is excellent for applications requiring superior corrosion resistance properties. It can be used in temperatures ranging from cryogenic to over 1000°F. ASTM B463 Nickel Alloy 20 Sheets come in various sizes and thicknesses. The most common type is the 2B finish sheet which is cold rolled with a bright annealed finish to ensure a smooth surface. This sheet type is highly resistant to corrosion and can be used in various industrial applications such as chemical processing, food processing, pharmaceuticals, paper industry, etc. It can be used in higher-temperature applications like petrochemical plants or nuclear reactors.

ASME SB463 Plates are mainly used in chemical process equipment like tanks, vessels, piping systems, etc., providing excellent corrosion resistance against organic acids like acetic acid, formic acid, etc. It also offers good resistance to stress corrosion cracking when exposed to chloride-containing environments. The plates are typically cut from larger sheets or rolled into coils before forming into desired shapes for specific applications. Alloy 20 Round Bars, Alloy 20 Flanges and many more grades are also available.

One major benefit of using Alloy 20 Coils for industrial applications is its ability to resist localized attack by intergranular corrosion caused by sulfuric acid or other acidic solutions at room temperature. This makes it an ideal material for use in chemical process plants that regularly handle these types of liquids or gases. It has superior creep-rupture strength compared to other materials making it suitable for high-pressure applications requiring long-term stability under extreme temperatures over extended periods without deforming or failing prematurely. Different types of products are available, such as SMO 254 UNS S31254 Pipe Fittings, Flat Bars, etc.

Alloy 20 Sheets & Plates
Nickel Alloy 20 Sheets provide excellent resistance against corrosive environments making it the ideal material for many different industrial applications requiring high levels of durability and performance under extreme conditions, such as high temperatures or harsh chemicals in some manufacturing processes. Its ability to resist localized attack by intergranular corrosion caused by sulfuric acid or other acidic solutions at room temperature helps protect components from premature failure due to environmental factors.
