ASTM A789 S32750 Duplex Steel Seamless Tube For Heat Exchanger Tube

Product Overview

The ASTM A789 S32750 Duplex Steel Seamless Tube is manufactured from S32750 duplex stainless steel, which combines both austenitic and ferritic properties to offer superior corrosion resistance, strength, and toughness. This tube is designed for heat exchanger systems, particularly in aggressive environments such as seawater, chemical processing, and petrochemical industries. Duplex steel ensures long-lasting performance in high-pressure, high-temperature applications, providing excellent resistance to stress corrosion cracking (SCC) and pitting corrosion.

Chemical Composition – ASTM A789 S32750 Duplex Steel

Mechanical Properties – S32750 Duplex Steel

Advantages
