UNS S31803 / S32205

Duplex 2205 strip

ASTM A240

Duplex 2205 strip combines duplex strength and chloride-corrosion resistance with a thin section for clips, shims and formed parts. Edge condition, temper and rolling direction affect both production feeding and the finished bend.

Raw Material Specifications

Heat Treatment

Solution annealed and rapidly cooled

Solution annealing followed by rapid cooling controls harmful precipitates and preserves the ferrite–austenite structure.

What we can make in Duplex 2205

Coiled strip

Coiled strip

Use for progressive stamping, spring clips and repeated forming. Strip width, thickness and coil dimensions must suit the tool and feed line to maintain consistent component geometry.

Cut strip length

Cut lengths

Use for short-run brackets, shims and fabricated pieces when coil handling adds unnecessary setup. Flatness and length tolerance help the blank seat consistently in the tool.

Strip camber relative to straight reference

Edge & camber

For narrow stamped or formed parts, control slit-edge burrs to protect tools and contact surfaces. Excess camber pulls the strip away from the intended feed path and affects registration.

Supply & preparation

Slitting and cut-length preparation follow the requested width, thickness and edge condition. Rolling direction is retained where the forming drawing needs it.

Material condition

Solution treatment and cooling control the duplex structure. Subsequent processing must preserve the ordered corrosion and mechanical condition.

Finished geometry

Thickness variation, edge burr, coil set and surface finish determine suitability for the next stamping or forming step.

Where Duplex 2205 fits — and what matters

Ship machinery compartment with green pumps, insulated pipes and pressure gauges

Offshore & Marine

Seawater pump and cooling-system covers

Duplex 2205 strip is slit and formed into shims, retaining clips or seal-support pieces around seawater pump and cooling-system covers. Thickness, edge finish and bend direction control the finished fit. The assembled contact is exposed to saltwater, deposits and neighbouring metals.

Water Treatment & Desalination

Filter housings and treatment-pump covers

Duplex 2205 strip is slit and formed into shims, retaining clips or seal-support pieces around filter housings and treatment-pump covers. Thickness, edge finish and bend direction control the finished fit. The water stream, cleaning cycle and retained liquid define exposure at the installed part.

Oil & Gas

Process valves and equipment closures

Duplex 2205 strip is slit and formed into shims, retaining clips or seal-support pieces around process valves and equipment closures. Thickness, edge finish and bend direction control the finished fit. Utility connections and pressure-boundary parts have separate acceptance requirements on the equipment drawing.

Duplex 2205 material data
UNS N06625

Inconel 625

Solid-solution strength and resistance to aggressive process liquids.

Connection priority
The stiffness and recovery of the formed strip section
Annealed or solution-annealed 625
The delivery condition affects strength and high-temperature response. Keep the specified condition with the component’s mechanical acceptance; 718-style aging is not the strengthening route for 625. Include liquid retained at slit edges, overlap faces and highly strained bends in the exposure description.

UNS S32750

Super Duplex 2507

Super-duplex strength and resistance to chloride pitting.

Connection priority
The stiffness and recovery of the formed strip section
Final duplex structure
S32750 chemistry and final solution treatment belong together. Forming, section size and cooling affect the structure represented by the mechanical and corrosion records. Include liquid retained at slit edges, overlap faces and highly strained bends in the exposure description.

UNS N05500

Monel K-500

Age-hardened strength in the nickel–copper alloy family.

Connection priority
The stiffness and recovery of the formed strip section
Strength and hydrogen exposure
K-500 gains strength through aging. Cathodic protection, hydrogen exposure and the ordered condition need joint consideration in highly loaded marine components. Include liquid retained at slit edges, overlap faces and highly strained bends in the exposure description.

Questions about Duplex 2205 strip

Why does edge condition belong on a strip order?

A slit edge can become the most highly strained edge during forming. Burr direction, edge finish and the chosen bend radius affect the next operation and the finished contact surface.
