Uses of Stainless Steel 2205 Duplex Sheets - SV Stainless Steel

Duplex stainless steel is a combination of austenite and ferrite structures. This type of stainless steel features excellent strength, toughness, oxidation resistance, and corrosion resistance. One of the most popular duplex stainless steels is 2205 duplex stainless steel, which has a higher chromium and nitrogen content, providing higher strength and better corrosion resistance than other types of stainless steel.

In this blog post, we will closely examine the uses of stainless steel 2205 Duplex Sheets!

Duplex Steel 2205 sheet is a nitrogen-enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steel. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex stainless steel consists of austenite pools surrounded by a continuous ferrite phase. In the annealed condition, ASTM A240 Duplex 2205 Sheets contain approximately 40-50% ferrite. The workhorse grade 2205 is often referred to as the most widely used grade in the duplex family of stainless steel.

Characteristics of Stainless Steel 2205 Duplex Sheets

  • High resistance to chloride stress corrosion cracking
  • Resistance to chloride pitting and crevice corrosion
  • Good general corrosion resistance
  • Good sulfide stress corrosion resistance
  • High Strength
  • Good weldability and workability

Uses of Stainless Steel 2205 Duplex Sheet:

Stainless Steel 2205 Duplex Sheet (UNS S32205) is widely applied in commercial and industrial settings for its exceptional robustness, tenacity, and resistance to corrosion. This category of steel is employed in a variety of capacities, from structural components of ships, boats, and well-drilling equipment, to tanks, pressure vessels, valves, and other piping systems. 

Furthermore, it is well-suited for use in pump shafts and other corrosive environments of great severity. Its ability to resist pitting and stress-corrosion cracking makes it particularly suitable for many high-demand saline water applications. Beyond these uses, it is also effective for use in cryogenic temperatures and in temperatures surpassing 300°F. Its duplex nature makes it amenable to being formed into bankable shapes with low-cost weldability in comparison to other stainless steels.

Applications of Stainless Steel 2205 Duplex Sheets

2205 (1.4462) Duplex sheets are used in various industries, including:

  • Chemical processing, transport, and storage – pressure vessels, tanks, piping, and heat exchangers
  • Oil and gas exploration and processing equipment – piping, tubing, and heat exchangers
  • Marine and other high-chloride environments
  • Pulp and paper industry – digesters, bleaching equipment, and stock-handling systems
  • Cargo tanks for ships and trucks
  • Food processing equipment
  • Biofuels plants and so on.
