Introduction:
Google Search Super Duplex Stainless Steel 2205 Coil
Duplex 2205 duplex stainless steel alloy is 22% chromium, 2.5% molybdenum, and 4.5% of nickel, nitrogen alloyed stainless steel. 2205 is characterised by:
1. high mechanical strength – roughly twice the proof strength of austenitic stainless steels.
2. physical properties that offer design advantages.
3 .good weldability.
4. high resistance to stress corrosion cracking in chloride-bearing environments and in environments containing hydrogen sulphide.
5. high resistance to general corrosion, pitting and crevice corrosion.
6. high resistance to erosion corrosion and corrosion fatigue.
Applications:
Alloy duplex 2205 Stainless Steel is used in a wide variety of home and commercial applications, 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.
Effluent scrubbing systems
Pulp and paper industry-digesters,bleaching equipment,and stock-handling systems.
Cargo tanks for ships and trucks
Food processing equipment
