Hastelloy C-22 strip
ASTM B575
Hastelloy C-22 strip combines corrosion resistance across oxidising and reducing process exposures with a thin section for clips, shims and formed parts. Edge condition, temper and rolling direction affect both production feeding and the finished bend.

Solution annealedSolution annealing dissolves detrimental precipitates, followed by rapid cooling to preserve corrosion resistance.
What we can make in Hastelloy C-22
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 C-22 fits — and what matters
Chemical Processing
Chemical pump covers and reactor connectionsHastelloy C-22 strip is slit and formed into shims, retaining clips or seal-support pieces around chemical pump covers and reactor connections. Thickness, edge finish and bend direction control the finished fit. Process liquid can remain at the contact after the exposed surface drains.
Pumps, Valves & OEM
Pump casings and valve bonnetsHastelloy C-22 strip is slit and formed into shims, retaining clips or seal-support pieces around pump casings and valve bonnets. Thickness, edge finish and bend direction control the finished fit. Repeated maintenance makes fit, engagement and access part of the component specification.
Mining & Mineral Processing
Chemical-recovery pump and vessel coversHastelloy C-22 strip is slit and formed into shims, retaining clips or seal-support pieces around chemical-recovery pump and vessel covers. Thickness, edge finish and bend direction control the finished fit. Leach solution and deposits act on the installed part; corrosion duty is separate from abrasive wear.
Same strip. Different material priorities.
Hastelloy C-22 material dataHastelloy C-276
Resistance to chemically aggressive, mixed process streams.
- Connection priority
- The stiffness and recovery of the formed strip section
- Process liquid and shutdown chemistry
- C-276 is selected for its nickel–chromium–molybdenum–tungsten chemistry. Residual product, cleaning liquid and oxidising contamination can expose a sheltered connection differently from the main flow. Include liquid retained at slit edges, overlap faces and highly strained bends in the exposure description.
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.
Titanium Grade 2
Low mass, corrosion resistance and commercially pure titanium formability.
- Connection priority
- The stiffness and recovery of the formed strip section
- Commercially pure titanium
- Grade 2 favours corrosion resistance and forming characteristics over the higher strength of Grade 5. Mating-metal contact, surface condition and assembly friction remain part of the connection design. Include liquid retained at slit edges, overlap faces and highly strained bends in the exposure description.

Questions about C-22 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.
