ASTM A789 / ASME SA789 S32205 Duplex Steel Tube
Overview
ASTM A789 covers seamless and welded ferritic/austenitic stainless steel tubing for general corrosion-resistant and low- or high-temperature service. S32205 is a specific grade of duplex stainless steel that is covered by this specification.
S32205, also known as Duplex 2205, is a duplex stainless steel that offers a combination of high strength and excellent corrosion resistance. It has a balanced microstructure of austenite and ferrite, which provides improved resistance to stress corrosion cracking, pitting, and crevice corrosion. This makes it suitable for a wide range of applications in industries such as oil and gas, chemical processing, desalination plants, heat exchangers, pulp and paper, and marine environments.
