ASTM A240 430 Cold Rolled Stainless Steel Sheet 1.5mm × 1219mm × 2438mm 2B

ASTM A240 430 Cold Rolled Stainless Steel Sheet 1.5mm × 1219mm × 2438mm 2B Finish is a ferritic stainless steel sheet manufactured for applications requiring good corrosion resistance, dimensional stability, attractive surface quality, and cost-effective performance.

This AISI 430 stainless steel sheet is supplied in a 1.5mm thickness with a 1219mm × 2438mm (48" × 96") size and a 2B cold rolled finish. Grade 430 contains chromium as the primary alloying element and is widely used in kitchen equipment, appliances, architectural components, automotive trim, and general fabrication.

Compared with austenitic grades such as 304, 430 stainless steel provides a lower-cost solution for applications where moderate corrosion resistance and good formability are sufficient.

Typical chemical composition requirements for ASTM A240 Type 430 stainless steel include:

Typical mechanical properties of annealed AISI 430 stainless steel sheet include:

The 2B finish is one of the most widely used cold rolled stainless steel finishes.

The typical production sequence includes:

Cold Rolling → Annealing → Pickling / Descaling → Skin Pass / Light Cold Rolling

The resulting surface is:

• Smooth
• Clean
• Relatively reflective
• Uniform in appearance
• Suitable for general fabrication
• Easy to clean
• Suitable for further polishing or decorative processing

The 430 2B stainless steel sheet can also be further processed into brushed, hairline or other decorative finishes when required.

AISI 430 contains approximately 16–18% chromium, providing good resistance to atmospheric corrosion and many mildly corrosive environments.

It is suitable for indoor and general-purpose applications where the corrosion conditions are not as severe as those requiring 304 or 316L stainless steel.

430 stainless steel performs well in applications exposed to moderate temperatures and oxidation conditions.

The 2B cold rolled finish provides a smooth, uniform surface suitable for general industrial and commercial applications.

430 contains little or no intentional nickel, making it generally more economical than 304 stainless steel.

It can therefore be an attractive option where the application does not require the higher corrosion resistance of 304.

For the supplied size:

1.5mm × 1219mm × 2438mm

the theoretical weight can be estimated using the density of 430 stainless steel.

Approximate calculation:

Weight = Thickness × Width × Length × Density

Using a density of approximately 7.7 g/cm³, the theoretical weight is about:

34.3 kg per sheet

Actual supplied weight may vary depending on dimensional tolerances and production conditions.

The production process for the 430 cold rolled stainless steel sheet generally includes:

Slab/Billet → Hot Rolling → Annealing & Pickling → Cold Rolling → Annealing → Surface Treatment → Skin Pass → Leveling → Cutting → Inspection → Packing

Cold rolling provides:

• Better thickness control
• Improved surface quality
• Better flatness
• Consistent mechanical properties
• Uniform 2B surface appearance

A: ASTM A240 Type 430 is a ferritic chromium stainless steel commonly supplied in sheet and plate form for applications requiring good corrosion resistance, oxidation resistance and cost efficiency.

A: Yes. Type 430 is a ferritic stainless steel and is magnetic.

A: 2B is a common cold rolled stainless steel surface finish produced through cold rolling, annealing, descaling/pickling and light skin passing. It provides a smooth and relatively reflective surface.

A: Neither grade is universally better. 430 is more economical and magnetic, while 304 generally offers better corrosion resistance and formability. Grade selection should be based on the application and service environment.

A: 430 can be used in some outdoor environments with moderate atmospheric exposure. However, highly humid, coastal or chloride-rich environments may require a more corrosion-resistant grade such as 304 or 316L.

A: Yes, 430 can be welded using suitable stainless steel welding procedures. However, welding performance differs from austenitic grades, so the welding process should be selected according to thickness and application.

A: Yes. The specified 1219mm × 2438mm size corresponds approximately to 48" × 96", subject to actual production tolerances and order requirements.

A: We can provide material documentation such as EN 10204 3.1 MTC, including chemical composition and mechanical test results, according to the order requirements.
