430 Stainless Steel Sheet

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 Stainless Steel Chemical Composition

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%

430 Stainless Steel Mechanical Properties

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 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.

430 Stainless Steel Sheet Surface Finishes

Frequently Asked Questions

What is 430 stainless steel sheet?

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.

Is 430 stainless steel magnetic?

Yes. 430 is a ferritic stainless steel and is normally magnetic, unlike annealed austenitic grades such as 304.

What is the difference between 430 and 304 stainless steel?

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.

Which surface finish is suitable for decorative 430 sheet?

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.
