In the field of razor manufacturing, the choice of materials directly determines the product's performance, service life and user experience. The core secret of a high-quality razor is often hidden in the stainless steel material it uses. This article will take you to an in-depth understanding of the scientific selection method of stainless steel materials for razors to help you make the best decision.
Choosing the right blade material first is critical to ensure sharpness, durability, corrosion resistance, and shaving comfort.
Hardness and sharpness
Razor blades need to be HRC 55+, and scalpels HRC 58-60 to ensure that the edge remains sharp.
Corrosion resistance
Need to resist pitting when exposed to water, sweat or body fluids.
Medical devices need to pass salt spray testing
Good edge sharpness
To achieve a smooth shave, the steel must be able to form an ultra-thin edge (typically less than 0.1 micron).
Why choose DSM razor blade steel?
DSM's 6Cr13 stainless steel, as a high-quality blade steel widely used in the industry, has become the best choice for economical and disposable razors due to its excellent corrosion resistance, moderate hardness and good processing performance.
Core Advantages
High corrosion resistance
Contains 13% chromium, which can effectively resist corrosion from moisture, sweat and shaving foam, ensuring safe and hygienic use.
Moderate hardness
After heat treatment, the hardness can reach HRC52-56, which is sharp and avoids brittleness, suitable for daily shaving.
Excellent processability
Whether cold rolling, stamping, quenching or polishing, 6Cr13 performs stably and can meet the needs of high-speed mass production.
High cost performance
Compared with high-end knife steel, 6Cr13 significantly reduces costs while meeting performance standards, making it an ideal choice for large-scale manufacturing.
Application
Primarily used in disposable razors, disposable scalpels, medical instruments, and other related fields.

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.
