Product Details

430 stainless steel is a ferritic stainless steel known for its excellent corrosion resistance, formability, and bright surface finish.

Unlike austenitic grades such as 304, it contains no or very little nickel, making it more cost-effective.
It is widely used for decorative panels, kitchen equipment, and automotive components due to its attractive surface appearance.

Chemical Composition of 430 Stainless Steel

Element	Typical Content (%)
Chromium (Cr)	16 – 18
Carbon (C)	≤ 0.12
Manganese (Mn)	≤ 1.0
Silicon (Si)	≤ 1.0
Phosphorus (P)	≤ 0.04
Sulfur (S)	≤ 0.03
Nickel (Ni)	≤ 0.75

Key Points:

Chromium provides good corrosion resistance
Low carbon content ensures ductility and formability
Nickel-free design reduces cost while maintaining bright surface finishes

Mechanical Properties

Property	Typical Value
Yield Strength	≥ 205 MPa
Tensile Strength	450 – 600 MPa
Elongation	≥ 22%
Hardness	≤ 95 HRB

Highlights:

Good balance of strength and ductility
Moderate hardness suitable for forming, bending, and stamping
Non-magnetic in annealed condition

Corrosion Resistance

Excellent resistance in indoor, mildly corrosive, or atmospheric environments
Less resistant than austenitic grades (304, 316) in chloride or marine conditions
Suitable for kitchen appliances, wall panels, and decorative trims

Fabrication and Processing

Welding

Weldable using standard methods, but post-weld corrosion resistance is slightly lower than austenitic grades

Machining

Good machinability due to low carbon content
Easy to cut, stamp, and roll

Surface Finishes

2B finish – standard industrial bright finish
BA finish – highly reflective mirror-like finish
HL (hairline) finish – decorative linear brushed texture

Common Applications of 430 Stainless Steel Sheet

Household Appliances

Refrigerator panels, ovens, and microwaves
Washing machine panels and dishwasher components

Architectural & Decorative

Wall panels, ceiling trims, and elevator panels
Decorative railings and handrails

Industrial & Automotive

Automotive trim components
HVAC panels and ducting
Light structural parts requiring corrosion resistance and formability
