Final pricing depends on raw material rates, finish (2B vs BA vs #4 vs #8), quantity, and delivery terms. Contact our sales team for a competitive quote.

Chemical Composition of Stainless Steel 430 Sheet

The table below shows the chemical composition of SS 430 Sheet according to ASTM A240 / ASME SA-240 (UNS S43000).

Chromium at 16.0–18.0% forms the passive oxide layer responsible for corrosion resistance. The absence of nickel separates Type 430 from austenitic grades like 304 and keeps material cost lower.

Carbon C
Max 0.12%
Manganese Mn
Max 1.00%
Phosphorus P
Max 0.040%
Sulfur S
Max 0.030%
Silicon Si
Max 1.00%
Chromium Cr
16.0 – 18.0%
Nickel Ni
Max 0.75%

Mechanical Properties of 430 Stainless Steel Sheet

Per ASTM A240 / ASME SA-240, Grade 430 sheet meets these minimum mechanical property values.

These are specification minimums; actual mill test results often exceed them. The 22% elongation confirms adequate ductility for bending, stamping, and moderate deep drawing.

Industrial Applications of 430 Stainless Steel Sheet

430 stainless steel sheet serves 4 primary sectors: appliance manufacturing, automotive trim, architectural uses, and food service equipment.

Appliance Manufacturing

Appliance panels, dishwasher liners, and range hoods account for the largest consumption of 430 SS sheet. The #4 brushed finish delivers a polished stainless look at a lower cost than 304.

Automotive Trim and Components

Grade 430 sheet is stamped into wheel covers, exhaust trim rings, and decorative mouldings. Intermittent oxidation resistance up to ~815°C.

Architectural and Decorative Uses

Interior wall cladding, elevator door panels, and column covers frequently use 430 sheet in BA or #8 mirror finish. The material holds up well in climate-controlled environments.

Food Service Equipment

SS 430 sheets are used in kitchen countertops, sinks, and serving trays. The grade is considered food safe for contact with dry and low-acid foods under FDA and EU food contact regulations.

430 Stainless Steel Sheet vs 304 Stainless Steel Sheet

Refer to the following comparison table to understand how the absence of nickel differentiates Type 430 from Type 304 in terms of magnetism and performance.

Feature SS 430 (Ferritic) SS 304 (Austenitic)
Nickel Content 0% (Nickel-free) 8.0% – 10.5%
Chromium Content 16.0% – 18.0% 18.0% – 20.0%
Magnetism Strongly Magnetic Non-Magnetic (Annealed)
Weldability Limited (Brittle in welds) Excellent
Ductility Moderate Superior
Corrosion Resistance Moderate (Indoor/Dry) High (General/Outdoor)
Cost Significantly Lower Higher (Due to Nickel)

Type 430 is ferritic: 16.0–18.0% chromium, no nickel. Type 304 is austenitic with 18.0–20.0% chromium and 8.0–10.5% nickel. Nickel stabilises the austenitic structure, giving 304 better ductility and weld integrity. 430 is magnetic; a magnet test distinguishes the two on a receiving dock.

Frequently Asked Questions:

Is 430 Stainless Steel Sheet food safe? +
Yes, Food-safe 430 stainless steel sheet is used in commercial kitchens and restaurants. All FDA and EU food contact regulations for dry and low-acid surfaces are met. Manufacturers specify this grade for service counters to meet tight regulations.
Is 430 Stainless Steel Sheet rust proof? +
430 stainless steel sheet offers good resistance to atmospheric corrosion and mild oxidation due to 16.0–18.0% chromium. It isn't fully rust proof in marine, chloride-rich, or acidic environments. For harsh exposure, grades like 304 or 316L perform better.
Can 430 Stainless Steel Sheet be welded? +
430 SS sheet can be welded, but pre-heating to 150–200°C and post-weld annealing at 790–815°C are recommended. These steps reduce grain growth and embrittlement. Weldability is more limited than 304 because 430 isn't stabilised.
Is 430 Stainless Steel Sheet magnetic? +
Yes, a 430 stainless steel sheet is magnetic. All ferritic grades are magnetic. This distinguishes 430 from non-magnetic austenitic grades like 304 and 316. A magnet test confirms whether incoming material is ferritic or austenitic.
What is the difference between 430 and 304 Stainless Steel Sheet? +
430 is a ferritic grade that costs less because it doesn't have nickel in it. 304 is an austenitic steel that has 8.0–10.5% nickel in it. This makes it very easy to weld and resistant to rust. Choose 430 for situations where cost is important and corrosion is not a big deal.
