Brushed
It is suitable for scenes such as chassis panels and decorative cosmetic parts that require a consistent texture direction; it is recommended to mark the drawing direction and visible surface in the drawings or notes.

Finishing
polish
Improves surface finish and appearance texture, suitable for visible and touch surfaces; if mirror effect is required, it is recommended to provide target reference.
electropolishing
It improves the micro surface condition while improving the smoothness. It is often used for parts that have higher requirements for cleanliness and appearance consistency (subject to engineering evaluation).
Passivation
Enhances corrosion resistance and improves surface stability; suitable for applications in humid, salt spray or mild chemical media environments.
Laser engraving
Suitable for serial number, nameplate information, logo and logo engraving; it is recommended to provide vector files and location and size instructions.
Why choose stainless steel_SUS316 (sheet metal fabrication)
Corrosion resistant and more stable
It performs more stably in humid, salt spray and mild chemical media environments, and is suitable for long-term use and sheet metal parts with higher environmental requirements.
Structural strength and reliability
It is used for structural parts such as chassis cabinets, brackets, connectors, etc., taking into account strength and durability; it is recommended to mark tolerances and conduct DFM review on key assembly parts.
Controllable appearance and texture
Supports appearance paths such as brushing/polishing/electrolytic polishing, suitable for visible surfaces and shell panel parts that require texture.
Marking and protection are more convenient
Optional passivation improves corrosion resistance and stability, and can be combined with laser engraving to achieve traceable marking, making it suitable for equipment and mass production management scenarios.
Recommended Applications
- Corrosion resistance is preferred: Sheet metal parts, casings and brackets used in humid/salt spray/oil pollution environments
- long-term use: Terminal parts that require more stable appearance and durability
- Appearance requirements: Texture control such as consistent drawing direction, polishing or electrolytic polishing is required
- Equipment structural parts: Chassis cabinets, panels, connectors, mounting brackets
It is not recommended to choose directly (it is recommended to change materials/change routes)
- Strong cost constraints and general environmental requirements: Can evaluate more economical materials such as SUS304/430 (subject to engineering evaluation)
- Extreme wear resistance/high hardness requirements: Recommend evaluation of heat-treatable stainless steel or other wear-resistant systems
- Extremely lightweight: Can evaluate aluminum alloy sheet metal and other solutions (depending on strength and environmental requirements)
- High decorative mirror grade: It is recommended to clarify appearance standards and evaluate process paths and costs.
Design and DFM Guidelines
- Plate thickness and bending priority definition: Please clarify the plate thickness, bending angle/number and key benchmarks in the 2D drawings; for bent parts, it is recommended to avoid arranging holes and sharp corner slots that are too close to the bending line.
- Appearance surface and drawing direction: Please specify the "front/back" and drawing direction for the visible appearance; if you are sensitive to the visibility of the weld, please indicate the appearance grade in the remarks.
- Hole location and assembly: It is recommended to mark tolerances and benchmarks for key hole positions/fitting holes; if more stable assembly positioning is required, priority should be given to using positioning edges/positioning holes and providing 2D markings.
- Welding and deformation control: For large-area thin plates or multi-solder joint structures, it is recommended to use stiffeners/flanges and a reasonable welding sequence to reduce the risk of thermal deformation (the operating conditions can be explained in the remarks).
- Corrosion resistant path: If the use environment is humid/salt spray, it is recommended to evaluate passivation and cleaning and maintenance requirements; please indicate the medium and usage cycle in the remarks.
