Alloy 20 Products Manufacturer & Supplier in India

Alloy 20 is a type of austenitic stainless steel alloy that is designed to have good corrosion resistance particularly in the sulfuric acid environment. The alloy 20 material is also extensively applied in chemical processing, food processing plants, pharmaceutical, oil and gas as well as marine industries where acidic and aggressive media resistance is of great importance.

The attribute that makes Alloy 20 products superior in many aspects is that they are resistant to sulfuric acid, phosphoric acid, as well as nitric acid. Alloy 20 has better mechanical capacity, good fabrication and long-term durability, thus it has become a favorite nickel-iron-chromium alloy in the challenging industrial environments.

Frequently Asked Questions About Alloy 20 Products

Is Alloy 20 better than stainless steel?

Alloy 20 offers superior corrosion resistance compared to standard stainless steels, especially in sulfuric acid and acidic environments, making it a better choice for chemical and process industries.

Is Alloy 20 magnetic?

No, Alloy 20 is generally non-magnetic in the annealed condition due to its fully austenitic structure. However, slight magnetism may occur after cold working.

What is Alloy 20 material used for?

Alloy 20 is widely used in chemical processing equipment, sulfuric acid plants, heat exchangers, pharmaceuticals, food processing units, and marine applications.

What makes Alloy 20 unique for sulfuric acid applications?

The addition of copper and niobium (columbium) gives Alloy 20 exceptional resistance to sulfuric acid and prevents intergranular corrosion, especially during welding.
