ASTM A789 UNS S31803 Duplex 2205 seamless tube is a high-quality product that is widely used in many industries for its exceptional properties. The seamless tube is made from a duplex stainless steel which has excellent resistance to corrosion, high strength, and excellent toughness.
The ASTM A789 specification covers the standard requirements for seamless tubes that are made from duplex 2205 stainless steel. Duplex stainless steels are made up of a mixture of austenitic and ferritic stainless steels, which provide improved corrosion resistance and high strength properties. The duplex 2205 stainless steel is a cost-effective and reliable material that is commonly used in many industries including chemical processing, marine, oil and gas, pulp and paper, and more.
