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.

Type 430 is a chromium-based ferritic stainless steel. Its relatively simple alloy system is one reason it can provide an economical alternative to nickel-bearing austenitic grades for suitable service environments.
| Grade | C | Mn | Si | P | S | Cr | Ni |
|---|---|---|---|---|---|---|---|
| 430 | ≤0.12% | ≤1.00% | ≤1.00% | ≤0.040% | ≤0.030% | 16.0–18.0% | ≤0.75% |
Mechanical properties depend on thickness, processing condition and the applicable material specification. The following values are retained from the existing product page as general reference data.
| Tensile Strength | Yield Strength (0.2% Offset) | Elongation |
|---|---|---|
| 450 MPa | 205 MPa | 22% |
Final acceptance values should follow the applicable standard, ordered thickness and batch-specific material certificate.
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.
430 stainless steel sheet can be supplied with different surface finishes according to appearance, fabrication and end-use requirements. The original product range includes 2B, BA, No.1, No.3, No.4, HL and polished finishes.
| Finish | Surface Character | Typical Applications |
|---|---|---|
| 2B | Smooth cold-rolled finish with a moderate reflective appearance | Appliances, fabrication, equipment and general sheet applications |
| BA | Bright annealed surface with higher reflectivity | Decorative parts, appliances and visible components |
| No.3 | Coarse polished finish | Kitchen equipment and architectural fabrication |
| No.4 | Brushed / polished finish with a uniform directional appearance | Kitchen equipment, appliances and decorative panels |
| HL | Hairline finish with continuous polishing lines | Interior decoration and architectural components |
| No.1 | Hot-rolled, heat-treated and pickled surface | Industrial fabrication and thicker plate applications |
430 stainless steel sheet can be supplied as standard sheets or processed according to downstream fabrication requirements.
| Processing | Supply Capability |
|---|---|
| Cut-to-Size | Custom width and length according to order requirements |
| Slitting | Sheet and coil can be processed into narrower widths where applicable |
| Polishing | No.3 / No.4 / Hairline and other agreed decorative finishes |
| Protective Film | Available for finished surfaces when required |
| Fabrication | Cutting and other processing requirements can be reviewed according to drawings |
Inspection can be arranged according to the applicable material standard and confirmed purchase requirements. The original 430 sheet page includes both destructive and nondestructive inspection capabilities.
| Inspection Item | Purpose |
|---|---|

| Metallographic Testing | Available when metallurgical examination is required |
| Additional Inspection | Penetrant, corrosion or third-party inspection can be reviewed when applicable and specified before order |
430 stainless steel sheet is commonly selected for applications requiring an economical ferritic stainless steel with good appearance, formability and corrosion resistance in relatively mild service environments.
| Kitchen EquipmentAppliance panels and kitchen components | Home AppliancesRefrigerator, dishwasher and equipment panels | Automotive TrimDecorative and interior trim components |
| ArchitectureInterior panels and decorative fabrication | Food EquipmentSelected equipment in mild service conditions | Industrial FabricationPanels, covers and formed components |
Packaging is selected according to sheet thickness, dimensions, surface finish and transportation requirements. Finished decorative surfaces can receive additional protection to reduce scratching during handling and international shipment.
430 is a ferritic chromium stainless steel commonly identified as UNS S43000 and EN 1.4016. It is widely used for appliances, decorative components and general fabrication in relatively mild corrosion environments.
Yes. 430 is a ferritic stainless steel and is normally magnetic, unlike annealed austenitic grades such as 304.
430 is a ferritic chromium stainless steel with lower alloy cost and magnetic behavior, while 304 is an austenitic chromium-nickel stainless steel with generally better corrosion resistance and broader use in demanding environments.
BA, No.4 and hairline finishes are commonly considered for visible decorative components. The correct finish depends on the required appearance, fabrication process and cleaning conditions.
