ASTM A790 S31803 Duplex Steel Seamless Pipe

 

 

 

ASTM A790 S31803 is a specification for seamless duplex steel pipes. Duplex steel is a type of stainless steel that contains both austenitic and ferritic microstructures, providing excellent strength and corrosion resistance.

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

These pipes 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.
