Supply Form
For razor blade steel, DSM provides precision stainless steel cold-rolled strips in coil form.
| Thickness | Thickness Tolerance | Width | Width Tolerance | ||
| mm | Inches | mm | mm | inches | mm |
| 0.075-0.1 | 0.003-0.004 | MIN ±0.003mm | 1.2-700 | 0.047-27.560 | MIN ±0.02 |
| 0.12-0.5 | 0.005-0.020 | MAX ±0.005mm | - | - | MAX ±0.1 |
Precision stainless steel cold-rolled strips are wound on plastic reels with an inner diameter of 280 mm (11.024 inches). The maximum outer diameter of the steel strip reel is 870 mm (34.252 inches). This means that a single strip with a width of 22.1-22.4 mm (0.870-0.882 inches) can have a maximum weight of approximately 91-93 kg.
(Note: Delivery sizes and special dimension requirements can be customized as per request.)
Surface
To meet various customer needs, we offer a range of surface finishes, including 2B matte, 2B surface, and 2B bright. The surface roughness (Ra) ranges from 0.04 to 0.08 µm.
Packaging
DSM uses various packaging standards to ensure that products are neatly and attractively packaged. The packaging provides protection against rust, moisture, dust, pressure, impact, and scratches, ensuring that the materials arrive at the customer's warehouse in perfect condition. Small wooden blocks are placed between the strips to facilitate easy handling.
Lable
Each steel strip is labeled with relevant material information, including coil number, steel grade, dimensions, and net weight. Additionally, a main sample is included with each bundle to facilitate customer inspection and testing.
