ASTM A240 304 Brushed Stainless Steel Sheet 1.5mm × 1219mm × 2438mm No.4 Finish

Products Description

The 304 stainless steel material offers a practical combination of corrosion resistance, formability, weldability, and surface appearance, making this brushed sheet suitable for both decorative and functional applications. It can be used for elevator panels, wall cladding, kitchen equipment, machine covers, architectural components, furniture panels, and other fabricated parts.

For project requirements that differ from the standard 1.5mm × 1219mm × 2438mm size, custom cutting and cut-to-size service are available. PVC protective film can also be provided to help protect the No.4 brushed surface during processing, handling, transportation, and installation.

Chemical Composition of 304 Stainless Steel

No.4 brushed finish is a commonly used stainless steel surface finish produced by abrasive grinding to create a consistent, directional satin texture. On 304 brushed stainless steel sheet, the No.4 finish provides a uniform appearance with a controlled linear grain pattern rather than the smooth reflective surface of a 2B finish.

For architectural and fabricated products, No.4 brushed stainless steel offers a balance of appearance, durability, cleanability, and practical surface performance. It is commonly selected for elevator panels, kitchen equipment, wall cladding, furniture components, and decorative metalwork.
The surface direction and appearance can vary slightly depending on the abrasive process and production conditions. For projects requiring consistent appearance across multiple sheets, surface inspection and finish matching are recommended before bulk production.

No.4 vs 2B Stainless Steel Finish

This ASTM A240 304 brushed stainless steel sheet is supplied in the specified 1.5mm × 1219mm × 2438mm size with a No.4 brushed finish. The 1219mm × 2438mm format is suitable for applications where standard sheet dimensions are preferred for fabrication and material planning.

Standard Product Size

The theoretical weight of a 1.5mm × 1219mm × 2438mm 304 stainless steel sheet can be estimated using a density of approximately 7.93 g/cm³.

Calculation:

1.5 × 1219 × 2438 × 7.93 ÷ 1,000,000 ≈ 35.3 kg/sheet

Therefore, one sheet of ASTM A240 304 stainless steel, 1.5mm × 1219mm × 2438mm has a theoretical weight of approximately 35.3 kg.

 The combination of 304 stainless steel and No.4 brushed finish makes this sheet suitable for applications requiring both functional corrosion resistance and a uniform decorative surface.

When selecting brushed stainless steel sheet, grade and surface finish should be considered separately. No.4 describes the surface appearance, while 304, 316L, and 430 describe different stainless steel grades.

304 vs 316L Brushed Stainless Steel Sheet

304 is widely used for general architectural, kitchen, fabrication, and industrial applications. 316L contains molybdenum and generally provides better resistance to chloride-related corrosion, making it more suitable for marine, coastal, chemical, and other demanding environments.

For general-purpose applications where extreme chloride resistance is not required, 304 No.4 brushed stainless steel sheet can provide a practical combination of performance and cost.

304 vs 430 Brushed Stainless Steel Sheet

304 is an austenitic stainless steel, while 430 is a ferritic stainless steel. 304 generally offers better corrosion resistance and forming performance, while 430 is often selected for applications where cost, magnetic properties, and moderate corrosion resistance are important.

Our ASTM A240 304 Brushed Stainless Steel Sheet is supplied for customers requiring a defined grade, surface finish, and sheet size rather than generic stainless steel material.

Q1. What is ASTM A240 304 brushed stainless steel sheet?

A: It is a 304 / UNS S30400 stainless steel sheet manufactured to ASTM A240 requirements and supplied with a No.4 brushed surface finish. The brushed finish creates a directional satin appearance suitable for both decorative and functional applications.

Q2. What is the size of this 304 brushed stainless steel sheet?

A: The specified product size is 1.5mm thickness × 1219mm width × 2438mm length.

Q3. What does No.4 finish mean?

A: No.4 is a brushed stainless steel finish with a uniform directional satin grain. It is commonly used where a consistent decorative appearance is required.

Q4. Is 1.5mm 304 stainless steel sheet suitable for fabrication?

A: Yes. 304 stainless steel has good formability and weldability, making 1.5mm sheet suitable for many fabricated components, panels, kitchen equipment, and architectural applications.

Q5. How much does a 1.5mm × 1219mm × 2438mm 304 sheet weigh?

A: The theoretical weight is approximately 35.3 kg per sheet, based on a density of 7.93 g/cm³.

Q6. Can you provide custom sizes?

A: Yes. Cut-to-size 304 brushed stainless steel sheet can be supplied according to customer requirements, subject to available material dimensions and processing capabilities.

Q7. Can the No.4 surface be protected with PVC film?

A: Yes. PVC protective film can be applied to help protect the brushed surface from scratches and contamination during handling, cutting, transportation, and installation.
