ASTM A789 UMS S32205 Duplex Steel Seamless tube Resistant To Seawater Corrosion

ASTM A789 S32205 Duplex Steel Seamless tube Resistant To Seawater Corrosion

ASTM A789 S31803/S32205 is a specification for seamless duplex steel tube. Duplex steel is a type of stainless steel that contains both austenitic and ferritic microstructures, providing excellent strength and corrosion resistance.

Seamless Tubes are manufactured without any welding seams, which makes them more reliable and suitable for high-pressure and high-temperature applications.

These tube are commonly used in industries such as oil and gas, chemical processing, and marine engineering. They are known for their superior performance in harsh environments and are highly resistant to corrosion, pitting, and cracking.
