Stainless Steel Strip Product Series
Stainless steel strip, also known as narrow stainless steel coil or SS strip, is typically sold in coil form. Based on different surface finishes and material grades, it can meet the diverse needs of users in various fields regarding corrosion resistance, heat resistance, formability, and aesthetic appearance.
Classification by Surface Finish Series
The surface treatment determines the appearance, glossiness, and stain resistance of the stainless steel.
No.1/2D Stainless Steel Strip (Hot Rolled/Cold Rolled Dull Finish)
- No.1 features a hot-rolled surface, which is rough with visible rolling textures and high strength. 2D is a cold-rolled and annealed surface, slightly dull, non-reflective, and cost-effective.
- Surface Characteristics: No.1 is rough with texture; 2D is smooth but matte. Both are wear-resistant and impact-resistant.
- Processing Characteristics: Suitable for heavy-load, wear-resistant applications.
2B Stainless Steel Strip (Matte Finish)
- Produced by slitting stainless steel coils that have undergone cold rolling, annealing, pickling, and skin pass rolling. The surface is uniformly matte, smooth, and flat. This is the most common type of stainless steel strip surface.
- Surface Precision: Ra ≤ 0.4μm, smooth with no scratches, oxidation, or inclusions.
- Features: Uniform and smooth surface, medium gloss, less prone to fingerprints, and the most widely used surface.
BA Stainless Steel Strip (Bright Annealed Finish)
- The surface is bright annealed, resulting in a mirror-like, highly reflective finish.
- Surface Precision: Ra ≤ 0.1μm, uniform mirror effect, no scratches, pits, or color difference.
- Features: Good ductility, excellent gloss, fine surface texture, more decorative than 2B.
No.4 / HL Stainless Steel Strip (Brushed / Hairline Finish)
- Produced by mechanical grinding and polishing to create continuous linear textures, presenting uniform straight lines. HL (Hairline) features long, continuous lines, while No.4 has a coarser ground pattern.
- Brushed Types: Straight grain, non-directional grain. Texture coarseness can be customized (#400-#1200).
- Features: Unique metallic textured pattern, scratch-resistant, effectively conceals minor scratches, wear-resistant.
8K Stainless Steel Strip (Mirror Finish)
- Undergoes fine grinding and polishing to achieve a mirror-like surface with extremely high reflectivity.
- Surface Precision: Ra ≤ 0.05μm, reflectivity typically above 90%, surface free from any micro-scratches or pinholes.
- Features: Extremely bright, strong visual impact, clear and undistorted reflected images.
Patterned / Embossed Stainless Steel Strip
- Specific textures are pressed onto the surface using embossing rollers, such as diamond patterns, checkered/weave patterns, water droplet/pearl patterns, orange peel patterns, wood grain, stone/leather grain, etc.
- Processing Technology: Single-side embossing, double-side embossing, embossing + coloring.
- Features: Enhances three-dimensional effect, anti-slip, combines aesthetics with functionality.
Classification by Material Grade Series
The material grade determines the corrosion resistance, mechanical properties, and temperature resistance of the stainless steel.
Austenitic Stainless Steel Strip (300 Series)
- Main Grades: 304 (General-purpose, good corrosion resistance, most widely used), 316 (Contains molybdenum, better resistance to chloride ion corrosion, suitable for marine environments), 301 (Can achieve high strength through cold working, suitable for springs and shrapnel).
- Features: Non-magnetic, significant work hardening, excellent overall performance.
Ferritic Stainless Steel Strip (400 Series)
- Main Grades: 430 (Most common, good heat resistance, low thermal expansion coefficient), 410 (Martensitic series, can be strengthened by heat treatment).
- Features: Magnetic, low thermal expansion coefficient, strong oxidation resistance, relatively stable price.
Martensitic Stainless Steel Strip
- Main Grades: 420J2, 420J1.
- Features: Mechanical properties can be adjusted via heat treatment, high hardness, wear-resistant.

Advantages of Stainless Steel Strip
- Superior Corrosion Resistance: Relies on chromium, nickel, and molybdenum in the base material to form a passive film. Suitable for ordinary environments, coastal salt spray environments, and acidic/alkaline environments. Long service life, no additional anti-corrosion treatment required.
- High-Precision Slitting: All slitting processing is completed by Wanzhi Factory. Strips are ready for machine use upon arrival, eliminating secondary cutting, reducing processing waste, and improving production efficiency.
- Cost Optimization: Factory direct supply, no intermediate links, avoiding losses and labor costs associated with self-slitting.
- Processing Flexibility: Stainless steel offers excellent ductility, high slitting precision, and a smooth surface, allowing for smooth deep processing such as bending, stamping, welding, cutting, and roll forming.
- Diverse Surfaces: Covers various surface types like 2B, BA, HL, No.1, and various materials like 201, 304, 316, allowing flexible selection based on application scenarios.
- Flexible Customization: Thickness, width, surface type, material, surface effect, protective film, coil weight, packaging, etc., can be customized according to the application field.

We use imported blades and high-precision equipment to strictly control the slitting gap. Burr height is typically controlled to ≤ 0.02mm, meeting the requirements of precision electronics stamping.
Yes, we support film lamination. We can apply PE protective film or PVC protective film to prevent surface scratches during transportation and stamping.
Yes, we provide free A4 size sample pieces or small coil samples (width as needed, length 1-2 meters) for you to test hardness, elasticity, and stamping performance.
For common grades and finishes (e.g., 304/2B), we have master coils in stock; slitting lead time is approximately 5-7 days. For special materials or custom surfaces (e.g., 316L/8K), it takes 15-30 days.
Typically, one coil is the standard. Sample orders or trial orders for first-time cooperation can be negotiated.
