Specifications

430 stainless steel sheet

430 stainless steel sheet and plate is a ferritic chromium stainless steel containing approximately 16–18% chromium, offering a practical balance between corrosion resistance, formability, and cost efficiency.
It is widely used in decorative, architectural, and appliance applications where good surface quality, magnetic properties, and moderate corrosion resistance are required.
Compared with austenitic grades such as 304, 430 stainless steel provides lower material cost and stable performance in non-aggressive environments, making it a common choice for large-area sheet applications.

Chemical Composition (Typical)

Heat Treatment of 430 Stainless Steel

1.Annealing

Temperature range: 815–900°C
Process: Heating followed by air cooling
Purpose: Improves ductility, relieves internal stress, and enhances formability

2.Stress Relieving

Applied after cold forming or machining
Helps reduce deformation risk during subsequent processing

3.Hardening

430 stainless steel cannot be hardened by heat treatment
Strength improvement relies mainly on cold working

4.Performance Balance

Proper annealing ensures stable ferritic structure, uniform surface quality, and consistent forming performance.

Features of 430 Stainless Steel Sheet / Plate

Corrosion Resistance: Good resistance to oxidation and mild corrosive environments; suitable for indoor and low-humidity applications.

Magnetic Property: Naturally magnetic due to ferritic structure, distinguishing it from austenitic grades such as 304.

Formability: Adequate formability for bending, cutting, and light stamping after annealing.

Cost Efficiency: Lower alloy content makes 430 more economical than nickel-containing stainless steels.

Surface Quality: Capable of achieving high-quality decorative finishes such as hairline and mirror.

Applications of 430 Stainless Steel Sheet / Plate

Decorative Panels: elevator interiors, wall panels, appliance housings; recommended thickness: 0.6–1.2 mm.

Kitchen & Household Appliances: backsplashes, oven panels, range hoods; recommended thickness: 0.8–1.5 mm.

Architectural Components: interior cladding, trims, partitions; recommended large sheets, 4×8 ft or 5×10 ft.

Automotive Decorative Parts: non-structural trims and covers; recommended thickness: 0.8–2.0 mm.

Industrial Panels: equipment covers and enclosures; recommended thickness: 2.0–6.0 mm.

FAQ – 430 Stainless Steel Sheet / Plate

Is 430 stainless steel suitable for outdoor use?
It can be used in mild outdoor environments but is not recommended for coastal or chloride-rich conditions.

Can 430 stainless steel sheet be welded?
Yes, but welding should be carefully controlled; post-weld annealing is recommended for critical applications.

Does 430 stainless steel rust easily?
Compared to carbon steel, corrosion resistance is much better, but it is lower than 304 or 316 stainless steel.

Is 430 stainless steel food safe?
It is commonly used in kitchen appliances, but prolonged exposure to acidic food environments should be avoided.
