430 Stainless Steel Sheet
Short Description:
430 Stainless Steel Sheet is a ferritic chromium stainless steel sheet offering good corrosion resistance, formability and an economical alternative to nickel-bearing austenitic grades for suitable environments. SAKY STEEL supplies 430 / UNS S43000 / EN 1.4016 sheet and plate to ASTM A240 / ASME SA240 with 2B, BA, No.4, HL, No.8 and other surface finishes, custom dimensions and processing available.
430 Stainless Steel Sheet Overview
430 Stainless Steel Sheet is a chromium-based ferritic stainless steel flat product combining good atmospheric corrosion resistance, formability, decorative surface capability and economical material cost.
Unlike 304 stainless steel, Type 430 does not rely on significant nickel alloying and is magnetic in normal conditions. It is widely selected for kitchen equipment, appliance panels, architectural trim, decorative components, automotive trim and general indoor fabrication where the higher corrosion resistance of 304 or 316 is not required.
SAKY STEEL supplies 430 / UNS S43000 / EN 1.4016 stainless steel sheet, plate, coil and strip in hot-rolled and cold-rolled conditions with 2B, BA, No.1, No.4, HL, mirror and other surface finishes.

430 vs 304 Stainless Steel Sheet
430 and 304 stainless steel sheets are both widely used, but their alloy structure, corrosion resistance, magnetic behavior and cost are different. Grade selection should be based on the service environment and fabrication requirements.
| Feature | 430 Stainless Steel | 304 Stainless Steel |
|---|---|---|
| Structure | Ferritic | Austenitic |
| Nickel Content | Low / residual nickel | Nickel-alloyed |
| Corrosion Resistance | Suitable for mild atmospheric and indoor environments | Better general corrosion resistance |
| Magnetic | Yes | Generally non-magnetic in annealed condition |
| Relative Material Cost | Generally lower | Generally higher |
| Typical Selection | Appliances, decorative trim, kitchen equipment and indoor architectural parts | Food processing, industrial equipment and more corrosive environments |
430 is not a direct substitute for 304 in every environment. Chloride exposure, cleaning chemicals, temperature, fabrication and required service life should be considered before material selection.
