Super Duplex 2507 plate & sheet
ASTM A240
Super Duplex 2507 plate and sheet provide super-duplex strength and resistance to chloride pitting for cut, formed or fabricated components. Thickness, flatness and thermal history determine how the stock becomes a usable cover, liner or structural section.

Heat Treatment
Solution annealed and rapidly cooledSolution annealing followed by rapid cooling controls harmful precipitates and preserves the ferrite–austenite structure.
What we can make in Super Duplex 2507
Plate
Use for machined covers, tube sheets and equipment plates. Include finishing allowance where machining must remove mill scale or achieve flat gasket and bearing faces.
Sheet
Use for formed covers, ducting and thermal shields where bendability and thickness consistency matter. Surface finish and grain direction can affect visible surfaces and bend quality.
Cut blanks
Use cut profiles to reduce workshop cutting and material waste before fabrication. Hole position, edge finish and heat-affected edges matter when the blank goes directly into forming or welding.

Supply & preparation
Plate or sheet is prepared as full pieces or cut blanks, with stock condition retained through cutting and identification.
Material condition
Solution treatment and cooling control the duplex structure. Subsequent processing must preserve the ordered corrosion and mechanical condition.
Finished geometry
Thickness, flatness, squareness and edge condition determine the usable blank.
Where Super Duplex 2507 fits — and what matters
Offshore & Marine
Marine equipment enclosuresSuper Duplex 2507 plate & sheet are cut and formed into marine equipment enclosures, support plates or cover blanks. Thickness and flatness set the available section before cutting, bending or joining. The assembled contact is exposed to saltwater, deposits and neighbouring metals.
Water Treatment & Desalination
Filtration-equipment coversSuper Duplex 2507 plate & sheet are cut and formed into filtration-equipment covers, support plates or cover blanks. Thickness and flatness set the available section before cutting, bending or joining. The water stream, cleaning cycle and retained liquid define exposure at the installed part.
Oil & Gas
Instrument and auxiliary-equipment enclosuresSuper Duplex 2507 plate & sheet are cut and formed into instrument and auxiliary-equipment enclosures, support plates or cover blanks. Thickness and flatness set the available section before cutting, bending or joining. Utility connections and pressure-boundary parts have separate acceptance requirements on the equipment drawing.
Same plate & sheet. Different material priorities.
Super Duplex 2507 material dataInconel 625
Solid-solution strength and resistance to aggressive process liquids.
- Connection priority
- Plate stiffness or the load carried by a formed 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 formed corners, cut edges and welded seams in the exposure description.
Monel K-500
Age-hardened strength in the nickel–copper alloy family.
- Connection priority
- Plate stiffness or the load carried by a formed 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 formed corners, cut edges and welded seams in the exposure description.
Duplex 2205
Duplex strength and chloride-corrosion resistance.
- Connection priority
- Plate stiffness or the load carried by a formed section
- S31803 or S32205
- The specified UNS fixes the chemistry. Solution treatment, section size and the ordered mechanical or corrosion tests establish the final duplex condition. Include liquid retained at formed corners, cut edges and welded seams in the exposure description.

Questions about Super Duplex 2507 plate & sheet
Which stock details matter beyond alloy and thickness?
Flatness, surface finish, edge preparation and any directional forming requirement influence the usable component. A cut blank also needs a heat identity that survives separation from the original sheet or plate.
