Alloy 20 (UNS N08020) is an austenitic, nickel-iron-chromium based super alloy with additions of Copper and Molybdenum which provide resistance to hostile environments, pitting, and crevice corrosion. It is also stabilized with Columbium to minimize carbide precipitation during welding. Alloy 20 appears to fall between both the stainless and nickel categories as it contains characteristics of both. It was designed for maximum resistance to acid attack and demonstrates superior resistance to stress-corrosion cracking in boiling 20% to 40% sulfuric acid, and also has excellent general corrosion resistance to sulfuric acid and to chloride stress corrosion cracking. Alloy 20 has good mechanical properties at both ambient and elevated temperatures, up to approximately 930°F (500°C) and is readily fabricated by usual industrial processes.

The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.
Alloy 20 was originally designed for use in sulfuric acid related applications; however, it is now frequently used in a wide variety of industries. Applications that commonly use Alloy 20 include:
