Duplex 2205 Plate Applications by Industry

3 sectors account for most Duplex 2205 plate orders:

Oil & Gas Industry

Alloy 2205 plates are commonly chosen for constructing offshore platform topsides and subsea manifolds due to their superior corrosion resistance.

Chemical Processing

This grade is commonly selected for fabricating pressure vessels and for manufacturing tubesheets in heat exchangers across process industries.

Marine & Desalination

DSS 2205 plates provide reliable performance in marine structures exposed to seawater and in structural frames for desalination reverse osmosis systems.

Duplex 2205 Plate vs 316 Stainless Steel Plate

For buyers comparing 2205 duplex stainless steel plate against 316L, the key factors are strength and chloride resistance. The table below explains in detail.

Parameter Duplex 2205 316L SS
Yield Strength (min) 450 MPa (65 ksi) 205 MPa (30 ksi)
Tensile Strength (min) 620 MPa (90 ksi) 485 MPa (70 ksi)
PREN (typical) ~35 ~25
Chloride SCC Resistance Up to 150 degrees C Limited above 60 degrees C
Relative Cost Higher per kg Lower per kg

Thinner Duplex 2205 sections can replace heavier 316L sections, lowering material weight and total project cost.

Frequently Asked Questions:

How thick is a 2205 Duplex Plate? +
Duplex 2205 plate comes in thicknesses from 3 mm to 150 mm per ASTM A240.
What is the difference between Duplex 2205 Plate and 316 SS Plate? +
The primary difference is strength. Duplex 2205 plate has a minimum yield of 450 MPa, compared to 205 MPa for 316L. Chloride stress corrosion cracking resistance is also far superior. It is reliable up to 150 °C versus roughly 60 °C for 316L.
What is the price of Duplex 2205 plate per kg? +
Prices range from ₹300 to ₹450 per kg in India and $8 to $15 in USD. Thickness, finish, and quantity are factors that affect the final rate.
Can Duplex 2205 Plate be welded? +
Yes. Use filler metal 2209 and keep interpass temperature below 150 °C. Avoid autogenous welding to prevent excessive ferrite.
What sizes of Duplex 2205 Plate are available? +
Duplex 2205 plate is available in thickness ranging from 3mm to 150 mm, width upto 2500 mm and length upto 12000 mm. Custom dimensions are available on request.
Is Duplex 2205 Plate suitable for marine applications? +
Yes. PREN of approximately 35 provides strong pitting resistance in seawater. Common uses include desalination plants, offshore platforms, and cargo tank linings.
What is the chloride resistance of Duplex 2205 Plate? +
The plate resists chloride stress corrosion cracking up to approximately 150 °C (302 °F). PREN of ~35 exceeds 316L's ~25. Service above 300 °C (572 °F) isn't recommended because of sigma phase embrittlement.
