Alloy 20, a nickel-iron-chromium austenitic stainless steel, is highly resistant to aggressive
media. It possesses copper content, rendering it resistant to sulfuric acid. Amardeep Steel stands
as a leading supplier and manufacturer, offering a wide range of Alloy 20 sheets and plates in
various shapes, types, and sizes.
Carpenter's 20 steel sheets can conform to the ASTMB463 specification, which encompasses stainless
steel sheets and plates for high-temperature and high-pressure services. The UNS N08020 plate
exhibits robustness with a minimum tensile strength of 551 MPa and a minimum yield strength of 241
MPa. Such strength makes it ideal for storage tanks, containers, and panels.
The WNR 2.4660 sheet demonstrates remarkable resistance against chloride ions, sulfuric acid, and other
corrosive media. Hence, these sheets can serve as effective cladding material for protecting other
corrosive structures. Moreover, the ASTM B463 Alloy 20 plate finds application in the food processing
and pharmaceutical industries, as well as in mixing tanks, agitators, pumps, valve parts, and more.
Our Alloy 20 steel provides a solution for mitigating stress corrosion cracking that can occur when
stainless steel interacts with chloride solutions. We supply Alloy 20 steel for various applications,
assisting in determining the appropriate quantity for your specific project. Its composition includes
carbon, chromium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, and sulfur. It
finds usage in control valves, pressure relief valves, centrifugal pumps, and more. Trust Amardeep Steel
for high-quality Alloy 20 sheets and plates tailored to your requirements.
