Duplex 2205 Stainless Steel

Why Duplex 2205 Stainless Steel ?

For jobs that need reliable steel métier and good corrosion resistance, Duplex 2205 Stainless Steel is the key. Because this 2205 Duplex stainless steel is both ferritic and austenitic, it syndicates the top benefits of both alloys. In the past, builders would have to detriment corrosion resistance in conversation for a strong and flexible steel. Though, with its high chromium and molybdenum levels, Duplex 2205 stainless steel will resist erosion and cracking while upholding an excellent degree of strength.

TYPICAL APPLICATIONS OF DUPLEX 2205 STAINLESS STEEL

Sideways with water treatment and electrical industries, 2205 is useful for a wide variety of industries, as found in numerous different products. For instance, this alloy is chiefly helpful for:

  • Heat exchangers, pipe, and tubes
  • For handling oil and gas
  • In desalination plants
  • Pressure vessels, pipe, and tanks
  • For processing and transporting chemicals
  • In process industries for chloride handling
