254 SMO strip
ASTM A240
254 SMO strip combines high-molybdenum austenitic resistance to chloride exposure with a thin section for clips, shims and formed parts. Edge condition, temper and rolling direction affect both production feeding and the finished bend.

What we can make in 254 SMO
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 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.
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
The final annealed or specified strengthened condition is linked to the lot; an aging treatment is not assumed for a solid-solution alloy.
Finished geometry
Thickness variation, edge burr, coil set and surface finish determine suitability for the next stamping or forming step.
Where 254 SMO fits — and what matters

Offshore & Marine
Seawater pump and cooling-system covers254 SMO 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 covers254 SMO 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 closures254 SMO 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.
Same strip. Different material priorities.
254 SMO material dataInconel 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.
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.
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 254 SMO 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.
