Super Duplex Steel Seamless Pipe ASTM A790 UNS S32750 Acid Resistant

Super Duplex Steel Seamless Pipe ASTM A790 UNS S32750 Acid Resistant


ASTM A790 S32750 Seamless Pipe is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel.


(UNS S32750) Duplex stainless steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment. It has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. Higher chromium, molybdenum and nitrogen content make it has a high ability to resist pitting corrosion, crevice corrosion and general corrosion.


Its impact strength is also very high. 2507 alloy is not suitable for use in a temperature environment higher than 570 ° C. Its toughness will decrease if it is in such an environment for a long time.

Duplex Stainless Steel Features


Duplex stainless steels have Austenitic and Ferritic stainless steel microstructure, and possess properties in two groups stainless steel, however, there are different.


Versus Austenitic

  • Higher yield strength
  • Greater corrosion resistance
  • Stress corrosion cracking resistance
  • Not common, used temperate under 250 C.
  • Fabricability not good as Austenitic
  • Strictly control heat treatment and welding process
  • Price stability

Versus Ferritic

  • Good toughness than Ferric, not hard
  • Greater corrosion
  • Fabricability is better
  • Better weldability
  • Wide usage than Ferritic
  • Higher price

APPLICATIONS:

  • Paper & Pulp Companies
  • High Pressure Applications
  • Oil and Gas Industry
  • Chemical Refinery
  • Pipeline
  • High Temperature Application
  • Water Pipe Line
  • Nuclear Power Plants
  • Food Processing and Dairy Industries
  • Boiler & Heat Exchangers
