Description

ASTM A312 UNS S31254 / 254SMO Duplex Stainless Steel Seamless Pipe

Duplex stainless steels are characterized by their high levels of both ferrite and austenite phases, which give them excellent strength and corrosion resistance. ASTM A312 254SMO / UNS S31254 duplex stainless steel seamless pipes are commonly used in industries such as chemical processing, oil and gas, and pulp and paper. These pipes are made using a seamless manufacturing process, which ensures that they have a uniform wall thickness and smooth surface finish. They are available in various sizes and thicknesses, and can be customized to meet specific requirements.
