High Quality Custom Cut 2B / BA / 8K Finish AISI, SUS Cold Rolled Stainless Steel Coil / Coils

1. Product Overview

Cold rolled stainless steel coil is used where stable thickness, clean surface finish, and corrosion-resistant stainless grades are required for downstream fabrication. This specification is suitable for custom cutting and slitting, and it covers the common industrial grades 201, 304, 316, and 430.

The product is supplied in coil form for further conversion into sheets, blanks, or formed parts. The main finish options in this page are 2B, BA, and 8K, which cover standard industrial processing, brighter visible surfaces, and mirror-type decorative applications.

2. Technical Solution

• The material is supplied as cold rolled stainless steel coil with selectable grade and finish.
• 2B finish is generally used for standard fabrication where a smooth cold rolled surface is required.
• BA finish is more suitable where a brighter and cleaner visible surface is needed.
• 8K finish is typically selected where a mirror-like decorative surface is required.
• Grade selection should match the service environment and fabrication route. 201 is commonly used where cost control is important. 304 is the general-purpose stainless choice for fabrication and indoor or moderate outdoor exposure. 316 is more suitable where stronger corrosion resistance is needed. 430 is often selected where ferritic stainless characteristics and cost balance are important.

4. Application

• This material is suitable for sheet cutting, slitting, panel fabrication, bending, welding, and general stainless steel processing.
• 304 coil is commonly used for general equipment panels, kitchen-related parts, decorative trim, and fabricated components.
• 316 coil is more suitable for applications with stronger corrosion exposure.
• 201 and 430 grades are commonly used for cost-sensitive fabricated parts, appliance-related panels, and general indoor applications where the selected grade matches the service condition.
• For appearance-focused products, BA and 8K finishes are more suitable than standard 2B.

​5. Processing

• The coil can be supplied for custom cut sheets, slitting, and downstream fabrication according to size requirement.
• It is suitable for shearing, bending, profiling, welding, polishing, and general sheet metal processing.
• When the final part requires a visible surface, finish selection should be confirmed before cutting and forming.
• Protective packing should be matched to surface requirement, especially for BA, mirror, and 8K type finishes.

​6. Advantages

• The thickness range of 0.30–4.0mm covers light to medium stainless coil processing requirements.
• The width range of 200–1220mm supports both narrow and mainstream sheet fabrication routes, while customized sizes are also available.
• 2B, BA, and 8K finishes allow the material to match standard industrial processing and decorative surface requirements.
• Multiple grade options make it easier to balance corrosion resistance, forming route, and cost target.
• The coil can be supplied in standard export packing or customized package according to shipment and surface protection needs.

​​7. How to Choose

• Choose 201 when cost control is important and the service environment is not highly demanding.
• Choose 304 for general stainless applications with balanced corrosion resistance and fabrication performance.
• Choose 316 when stronger corrosion resistance is required.
• Choose 430 when ferritic stainless sheet is acceptable for the application.
• Choose 2B finish for standard industrial processing.
• Choose BA finish when a brighter and cleaner surface is needed.
• Choose 8K finish when a mirror-like decorative surface is required.
