FAQs

What is the main difference between 430 and 304 stainless steel bars?
430 is ferritic and magnetic, offering lower cost and moderate corrosion resistance compared to 304's non-magnetic austenitic type.
Can 430 stainless steel be used for decorative applications?
Yes. With polishing (Ra≤0.8μm), it provides a bright surface suitable for visible fixtures and furniture parts.
Is 430 stainless steel magnetic?
Yes. It shows strong magnetism, which simplifies assembly in mechanical and appliance components.
Can Walmay supply custom lengths and diameters?
Yes. Bars can be cut to any length ≥0.5m, with diameters up to Φ200mm or more on request.
What industries commonly use 430 stainless steel bars?
Widely applied in furniture hardware, household appliances, kitchen utensils, and light machinery.
