Stainless Steel

Stainless steel is highly resistant to corrosion and rust, making it suitable for situations where a part may be exposed to the elements for a long period of time. Stainless steel is also fairly malleable and ductile. Fictiv offers multiple stainless steel alloys, including a food-safe variety.

Material Finish

The finish of stainless steel varies greatly depending on surface roughness, but it’s generally characterized as being more shiny than unfinished aluminum alloys, and slightly darker and more silver in color.

Stainless steel can also be media-blasted, sanded, hand-polished, and powder coated to achieve a multitude of surface finishes.

Design Recommendations

Min Wall Thickness：0.5 mm

Min End Mill Size：0.8 mm (0.03 in)

Min Drill Size：0.5 mm (0.02 in)

Max Part Size：1200 x 500 x 152 mm[(x,y,z] (mill) 152 x 394 mm [d,h] (lathe)

Undercuts：Square profile, full radius, dovetail profiles

Radii（Depth） ：

· Depth must not exceed 12x drill bit diameter.

· For end mills, depth must not exceed 10x drill bit diameter.

Cost Saving Tip：To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
