Product Description

ASTM A790 / ASME SA790 UNS S32750 Super Duplex Stainless Steel Seamless Pipes

 

 

A790 S32750 pipes refer to pipes made from the duplex stainless steel grade S32750, which is also known as 2507 stainless steel. These pipes are highly resistant to corrosion and have excellent mechanical properties, making them ideal for use in harsh environments such as offshore oil and gas platforms, chemical processing and marine engineering.

 

 

What are the characteristics of Duplex 2507 / UNS S32750?

  • High resistance to chloride stress corrosion cracking
  • High Strength
  • Superior resistance to chloride pitting and crevice corrosion
  • Good general corrosion resistance
  • Suggested for applications up to 600° F
  • Low rate of thermal expansion
  • Combination of properties given by austenitic and ferritic structure
  • Good weldability and workability
