Alloy 20 Pipes

Alloy 20 pipe is a high-performance stainless steel pipe specifically designed for exceptional resistance to corrosion, particularly in environments containing sulfuric acid. Made from a nickel-iron-chromium alloy with added copper and molybdenum, Alloy 20 demonstrates excellent resistance to pitting, stress corrosion cracking, and crevice corrosion. It is commonly used in industries such as chemical processing, pharmaceuticals, food production, and petrochemicals, where corrosive conditions are frequent. Its durability and strength make it ideal for transporting corrosive materials safely and effectively in demanding applications.

Alloy 20, also known as Carpenter 20 or UNS N08020, is a nickel-iron-chromium austenitic alloy with added elements such as molybdenum and copper, which provide it with exceptional resistance to corrosion, especially in sulfuric acid environments. This grade is highly effective against stress corrosion cracking, pitting, and crevice corrosion, making it ideal for use in aggressive environments in the chemical, pharmaceutical, food, and petrochemical industries. Its balance of strength, corrosion resistance, and workability makes Alloy 20 a popular choice for applications requiring reliability in challenging conditions.

The wall thickness of Alloy 20 pipe can vary widely depending on the pipe’s intended use, pressure requirements, and standards it must meet. Alloy 20 pipes are typically available in standard wall thicknesses such as Schedule 5, Schedule 10, Schedule 40, and Schedule 80, with measurements ranging from approximately 1.65 mm (for Schedule 5) up to 7.62 mm or more (for Schedule 80), depending on the pipe’s diameter. For specific applications, custom wall thicknesses can also be manufactured to meet precise operational and safety needs.
