304 Hairline Stainless Steel
304 hairline stainless steel combines excellent corrosion resistance with a refined brushed surface, making it one of the most popular materials for modern design and industrial use.
Its balance of performance, durability, and aesthetics ensures wide application across construction, decoration, and manufacturing industries. Choosing a professional supplier guarantees consistent finish quality and reliable long-term performance.
- Description
304 hairline stainless steel (also known as brushed stainless steel or HL finish) is a surface-treated 304 stainless steel sheet featuring fine, continuous linear textures. This finish combines the corrosion resistance of 304 stainless steel with an elegant, modern appearance, making it widely used in architecture, decoration, and industrial design.
The hairline finish not only enhances aesthetics but also improves surface durability and scratch resistance compared with mirror or plain finishes.
What is Hairline Finish (HL)?
Hairline (HL) is a surface processing method created by mechanical brushing or abrasive belt polishing:
- Produces uniform, straight grain lines
- Reduces surface reflectivity (matte finish)
- Improves resistance to fingerprints and minor scratches
- Provides a clean and modern metallic look
Chemical Composition of 304 Stainless Steel
| Element | Content (%) |
|---|---|
| Chromium (Cr) | 18.0 – 20.0 |
| Nickel (Ni) | 8.0 – 10.5 |
| Carbon (C) | ≤ 0.08 |
| Manganese (Mn) | ≤ 2.00 |
| Silicon (Si) | ≤ 1.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Iron (Fe) | Balance |
This composition provides excellent corrosion resistance and formability, making 304 the most widely used stainless steel grade.
Key Properties of 304 Hairline Stainless Steel
1. Excellent Corrosion Resistance
304 stainless steel offers strong resistance to oxidation, moisture, and mild chemicals, suitable for both indoor and semi-outdoor environments.
2. Decorative Surface Appearance
The hairline finish delivers a uniform brushed texture, widely used in modern architectural design.
3. Anti-Fingerprint and Scratch Resistance
Compared with mirror finishes, the brushed surface helps hide fingerprints and minor surface scratches.
4. Good Formability and Workability
304 stainless steel can be easily processed by cutting, bending, welding, and stamping.
5. Durability and Low Maintenance
The material maintains its appearance over time with minimal maintenance requirements.
Typical Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥ 520 MPa |
| Yield Strength | ≥ 205 MPa |
| Elongation | ≥ 40% |
| Density | ~7.93 g/cm³ |
