ASTM A790 S32205 Duplex Steel Pipe is a ferritic-austenitic stainless steel pipe that is commonly used in industrial applications due to its excellent strength and corrosion resistance. It is made from a combination of chromium, molybdenum, and nickel, which gives it superior resistance to pitting, crevice corrosion, and stress corrosion cracking.

The process of manufacturing ASTM A790 S32205 Duplex Steel Pipe involves two main stages: melting and fabrication. The steel is melted in an electric furnace, and then cast into various shapes such as billets or ingots. The next step involves forging, rolling, or drawing the steel into the desired shape and size. This process is followed by heat treatment, which ensures that the steel pipe has optimum strength and corrosion resistance.
