Monel K-500 plate & sheet
ISO 6208
Monel K-500 plate and sheet provide age-hardened strength in the nickel–copper alloy family for cut, formed or fabricated components. Thickness, flatness and thermal history determine how the stock becomes a usable cover, liner or structural section.

Raw Material Specifications
Heat Treatment
Annealed or age hardenedAnnealing provides a workable starting condition, while controlled aging develops the higher strength specified for age-hardened K-500.
What we can make in Monel K-500
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 the specified aging condition are recorded against the production lot; final dimensions are checked after thermal processing.
Finished geometry
Thickness, flatness, squareness and edge condition determine the usable blank.
Where K-500 fits — and what matters

Offshore & Marine
Marine equipment enclosuresMonel K-500 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 coversMonel K-500 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 enclosuresMonel K-500 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.
Monel K-500 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.
Super Duplex 2507
Super-duplex strength and resistance to chloride pitting.
- Connection priority
- Plate stiffness or the load carried by a formed 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 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 K-500 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.
