SUS430 Stainless Steel Sheet
SUS430 is a magnetic ferritic stainless steel with better corrosion resistance than unprotected carbon steel, generally less than 304, and a lower cost than many austenitic grades. Its relatively high thermal conductivity and low thermal expansion can be useful in heat-related structures. Ductility and weldability are more limited; complex deep drawing or demanding welds require assessment. Brushing and polishing provide useful cosmetic options.
Typical Applications
Appliance panels and liners, kitchen-equipment trim, indoor decorative panels, guards and structures requiring general corrosion resistance. Suitable for cost-sensitive cosmetic applications outside aggressive corrosive environments.
Reference Properties & Manufacturing Parameters
Reference values are indicative and are not guaranteed specifications. Material grade, stock condition, processing, test method and part geometry can change the result. A listed temperature is not a continuous-use rating.
| Dimensional tolerance | ±0.2 mm |
|---|---|
| Minimum wall thickness | 0.8 mm |
| Reference temperature range | ≤750 °C |
| Reference tensile strength | 450–600 MPa |
| Reference density | 7.7 g/cm³ |
- Reference values vary with grade, material condition, part geometry and manufacturing process. Confirm final specifications during drawing review.
- Temperature figures are source reference values; the test method, loading and exposure duration are not specified and must be confirmed for the application.
Finishing Options
Confirm compatibility with the exact material grade and application. Define cosmetic surfaces, coating thickness, masking and any dimensional or performance requirements before manufacture.
Design & Manufacturing Review
- Specify sheet grade, thickness, finish and rolling direction where relevant. Confirm the selected stock before finalizing bend geometry.
- Review bend radii, bend reliefs, hole-to-bend distances and fastener access. Flat patterns must account for the actual forming process.
- Define weld locations, cosmetic surfaces and any coating or masking requirements.
