Stainless Steel 430 Explained
Stainless Steel 430 is a general-purpose ferritic stainless steel offering good corrosion resistance in mild environments, excellent formability, and an attractive surface finish. With stable chromium content and non-hardenable characteristics, it is widely used in kitchen equipment, household appliances, decorative panels, architectural trim, and food processing equipment. Grade 430 provides dependable performance at a lower cost than austenitic grades, making it an economical solution for applications requiring aesthetic appeal and moderate corrosion resistance.

💡 Practical Difference in Use
Use Stainless Steel 430 when: good corrosion resistance, excellent formability, and moderate strength are required in non-critical applications, with cost-effectiveness. → Example: kitchen appliances, automotive trim, architectural panels, and decorative applications.
Applications of Stainless Steel 430 Sheets and Plates
Stainless Steel 430 is a ferritic stainless steel with approximately 16–18% chromium, offering good corrosion resistance, excellent formability, and magnetic properties for decorative and industrial applications.
- Kitchen & Household Appliances: Dishwashers, refrigerators, microwave panels, and sinks.
- Automotive & Trim Parts: Decorative trims, exhaust covers, and interior panels.
- Architectural & Decorative: Wall panels, cladding, and building facades.
When to Choose Stainless Steel 430?
Stainless Steel 430 is chosen for applications where good corrosion resistance, formability, and aesthetic finish are required, and high strength or extreme corrosion resistance is not critical.
Choose SS 430 when:
- Moderate corrosion resistance is sufficient
- Good formability and surface finish are important
- Used in household appliances, automotive trim, and architectural panels
- Magnetic stainless steel is preferred
- Cost-effective ferritic stainless steel is desired
