304 / 316 / 430 Cold Rolled Steel Strip In Coil With 2B / BA Finish, 7mm - 350mm Width

304 / 316 / 430 Cold Rolled Steel Strip In Coil With 2B / BA Finish, 7mm - 350mm Width

1．Product Overview

Cold rolled stainless steel strip coil is used where narrow width precision material and controlled surface finish are required. Compared with wider cold rolled stainless coil, strip material in 7mm–350mm width is more suitable for downstream slitting, roll forming, stamping, profiling, spring-related use, hardware fabrication, and precision component processing.

This specification covers 201, 202, 304, 316, and 430 grades, with 0.2–2.0mm thickness and 2B or BA finish. It is intended for users who need narrow-width stainless strip in coil form with selectable hardness and stable edge condition for further manufacturing.

2．Technical Solution

The product is supplied as cold rolled stainless steel strip after pickling, cold rolling, and annealing. This processing route determines the dimensional range, surface condition, and hardness selection of the finished strip.

2B finish is generally used where a standard cold rolled industrial surface is required. BA finish is more suitable where a brighter surface appearance is needed. Hardness can be selected as fully hard, half hard, or soft quality according to bending, stamping, profiling, or springback control requirements.

For narrow-width stainless strip, width tolerance, coil build, hardness state, and surface finish are the main factors that affect downstream forming efficiency and finished-part consistency.

3．Specifications

4．Application

• This material is suitable for automobile manufacturing and vehicle-related strip components.
• It can be used for electrical products, electric metal boxes, and precision instrument parts.
• It is also suitable for telescopic slide channel production, hardware components, U profile, C profile, and shutter rolling door parts.
• For stainless strip routes requiring narrow width coil, it can also be used in hollow section, steel pipe tube manufacturing, aerospace-related fabricated parts, and canned food package components depending on grade selection.

5．Processing

• The coil can be supplied in strip form for direct recoiling and secondary slitting.
• It is suitable for bending, stamping, profiling, roll forming, and narrow-width fabrication.
• Grade and hardness should be selected according to final forming route. Softer condition is generally more suitable for deeper forming or repeated bending, while higher hardness is more suitable where higher rigidity or spring property is needed.
• Surface finish should be selected according to whether the final application is appearance-oriented or process-oriented.

6．Advantages

• The 7–350mm width range is suitable for narrow stainless strip processing rather than wide sheet applications.
• The 0.2–2.0mm thickness range covers light to medium stainless strip fabrication requirements.
• 2B and BA finishes provide two different surface options for industrial use and brighter appearance use.
• Multiple grades including 304, 316, and 430 allow users to match corrosion resistance, cost, and forming route to the final application.
• Fully hard, half hard, and soft quality options allow the strip to be selected according to downstream bending and profiling requirements.

7．How to Choose

• Choose 304 when general corrosion resistance and broad application compatibility are required.
• Choose 316 when stronger corrosion resistance is needed, especially in more demanding service conditions.
• Choose 430 when cost and ferritic stainless characteristics are more important than austenitic grade performance.
• Choose 2B finish for standard industrial processing applications.
• Choose BA finish when a brighter surface appearance is required.
• Choose soft quality for deeper forming and repeated bending.
• Choose fully hard or half hard when the final part requires more rigidity or higher springback control.
