Winfast Steel Export Duplex Steel 2205 Plate To South Koera

 

Winfast Steel Export  150 tons Duplex Steel 2205 Plate To South Koera

 

 

SAF 2205 is a duplex (austenitic-ferritic) stainless steel characterized by:

  • High resistance to stress corrosion cracking (SCC) in chloride-bearing environments
  • High resistance to stress corrosion cracking (SCC) in environments containing hydrogen sulfide
  • High resistance to general corrosion, pitting, and crevice corrosion
  • High resistance to erosion corrosion and corrosion fatigue
  • High mechanical strength - roughly twice the proof strength of austenitic stainless steel
  • Physical properties that offer design advantages
  • Good weldability
