- Descripción
304 hairline stainless steel (also known as brushed stainless steel or HL finish) es un surface-treated 304 hoja de acero inoxidable featuring fine, continuous linear textures. This finish combines the corrosion resistance of 304 acero inoxidable with an elegant, apariencia moderna, making it widely used in arquitectura, decoración, 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)?
Línea de pelo (HL) is a surface processing method created by mechanical brushing or abrasive belt polishing:
- Produces uniform, straight grain lines
- Reduces surface reflectivity (acabado mate)
- Improves resistance to fingerprints and minor scratches
- Provides a clean and modern metallic look
Composición química de 304 Acero inoxidable
| Elemento | Contenido (%) |
|---|---|
| Cromo (cr) | 18.0 – 20.0 |
| Níquel (En) | 8.0 – 10.5 |
| Carbón (do) | ≤ 0.08 |
| Manganeso (Minnesota) | ≤ 2.00 |
