Figure-8 Stainless Steel Profile Wire
Short Description:
Figure-8 Stainless Steel Profile Wire is a precision-shaped stainless steel wire with a double-lobe or figure-eight cross section for custom mechanical, guiding, sealing, retaining and industrial assemblies. SAKY STEEL supplies Figure-8 profile wire in 304, 316 and other stainless steel grades with customized overall width, lobe dimensions, center-web thickness, radius, tolerance and delivery form according to customer drawings.
Figure-8 Stainless Steel Profile Wire Overview
Figure-8 Stainless Steel Profile Wire is a precision-shaped stainless steel wire with a double-lobe or figure-eight cross section. The profile can provide two enlarged working areas connected by a narrower center section for positioning, retaining, guiding, sealing or custom mechanical functions.
SAKY STEEL supplies Figure-8 profile wire in 304, 316 and other stainless steel grades. Overall width, lobe dimensions, center-web thickness, overall height, corner radius, tolerance and delivery form can be customized according to customer drawings.
Because Figure-8 profile geometry can vary between applications, final dimensions should be defined by an approved cross-sectional drawing rather than profile name alone.

Figure-8 Profile Design
A Figure-8 cross section normally consists of two enlarged lobes connected by a narrower center section. The two lobes can be equal or different depending on the mating component and mechanical function.
| Profile Parameter | Description |
|---|---|
| Overall Width | Maximum width across the complete Figure-8 section |
| Upper / First Lobe | Width, height and radius according to drawing |
| Lower / Second Lobe | Equal or different dimensions according to design |
| Center Web | Connecting section thickness between the two lobes |
| Overall Height | Total height of the complete cross section |
| Radius | Internal and external radii according to profile design |
| Tolerance | Critical dimensions controlled according to approved drawing |
Custom Figure-8 Cross Sections
Figure-8 profile wire can be produced with symmetrical or asymmetrical lobes. The center connecting section, working surfaces and radii can also be adjusted according to installation and mechanical requirements.

304 vs 316 Figure-8 Stainless Steel Wire
| Grade | Main Characteristic | Typical Selection |
|---|---|---|
| 304 | Good general corrosion resistance and forming capability | General mechanical and precision-profile applications |
| 316 | Improved corrosion resistance in chloride-containing environments | Marine, chemical and more demanding wet-service applications |
Figure-8 Profile Wire Manufacturing
The production route depends on stainless steel grade, lobe geometry, center-web thickness, cross-sectional area, dimensional tolerance and delivery condition.
Complex profiles may require multiple forming passes to achieve the specified lobe geometry and dimensional consistency.
