6Cr13 is a martensitic stainless steel belonging to the medium carbon stainless steel series, mainly obtained through quenching and tempering treatment to achieve high hardness and wear resistance

The following are the main features of 6Cr13:

Carefully designed microstructure

Good grinding hardening and hardening performance

Supply Form

For razor blade steel, DSM provides precision stainless steel cold-rolled strips in coil form.

Supply size

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

(Length: coil type or it can be produced as customer requirements)

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.

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.

The edges of the steel strips are trimmed with burr heights of 0.001-0.002 mm. For special edge requirements, additional edge grinding treatments can be provided.

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.

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.

Microstructure

The size and quantity of carbides are crucial to the razor blade edge;

Carbides can be improved through optimization of rolling and annealing
