High Quality 7mm - 350mm Width 201 / 202 / 304 Cold Rolled Stainless Steel Strip In Coil

High Quality 7mm - 350mm Width 201 / 202 / 304 Cold Rolled Stainless Steel Strip In Coil

１．Product Overview

Cold rolled stainless steel strip coil is used where narrow width material, controlled thickness, and stable surface finish are required for downstream fabrication. This product range covers 201, 202, 304, 316, and 430 grades in 0.2–2.0mm thickness and 7–350mm width, making it suitable for precision strip applications rather than wide sheet processing.

The product is supplied in coil form and can be processed into cut sheets or stamped circles. For actual use, the main selection factors are grade, hardness, surface finish, edge condition, and strip width.

２．Technical Solution

The strip is produced by cold rolling and can be supplied after pickling, straightening, flattening, and leveling. This route is used to control strip geometry and surface condition for further processing.

2B finish is suitable for standard industrial use where a smooth cold rolled surface is required. BA finish is used where a brighter surface appearance is needed. The product can also be supplied in different hardness conditions, including fully hard, half hard, and soft quality, depending on whether the downstream route needs higher rigidity or better forming performance.

For narrow stainless strip, thickness tolerance, width tolerance, edge quality, and hardness state directly affect bending consistency, stamping behavior, and yield in secondary processing.

３．Specifications

４．Application

This material is suitable for narrow-width stainless strip processing in automotive parts, electrical products, hardware, and precision fabricated components.

It can also be used for telescopic slide channel parts, stamped components, cut sheets, and circular blanks where controlled width and surface finish are important.

For applications requiring corrosion resistance and stable strip supply in coil form, 304 and 316 are commonly selected. For more cost-sensitive applications, 201, 202, or 430 may be used according to the service environment.

５．Processing

• The coil can be supplied for direct recoiling, cut-to-length processing, and stamping.
• Mill edge is suitable where original edge condition is acceptable in the downstream route. Slitting edge is more suitable where narrower width control is required.
• Soft quality is generally selected for forming and bending. Fully hard or half hard is more suitable where the final part needs higher rigidity or spring effect.
• Inter paper and PVC protecting film can be added when surface protection is required during storage and fabrication.

６．Advantages

• The 7–350mm width range is suitable for narrow stainless strip processing where wide sheet is not practical.
• The 0.2–2.0mm thickness range covers light to medium strip fabrication requirements.
• 2B and BA finishes provide two practical surface options for industrial use and brighter appearance use.
• Multiple grades allow material selection according to corrosion resistance, fabrication route, and cost target.
• Controlled tolerance and selectable edge condition help improve secondary processing stability in bending, stamping, and slitting applications.

７．How to Choose

• Choose 201 or 202 when cost control is important and the service environment is not highly demanding.
• Choose 304 for general corrosion-resistant strip applications with broad processing compatibility.
• Choose 316 when stronger corrosion resistance is required.
• Choose 430 when ferritic stainless characteristics are acceptable for the application.
• Choose 2B finish for standard industrial processing and BA finish for brighter visible surfaces.
• Choose soft quality for forming and bending, and choose fully hard or half hard when higher rigidity is needed.
