Alleima® 13C26 is a martensitic stainless steel designed for razor blades, surgical instruments, and precision cutting tools. It delivers exceptional sharpness, durability, and corrosion resistance, ensuring long-lasting edge retention and hygienic properties.
Supplied as cold-rolled strip steel with tight dimensional tolerances, superior flatness, and high straightness accuracy, it guarantees efficient razor production and consistent blade quality.

Why choose Alleima’s razor blade steel?
Optimal hardness and sharpness - our 13C26 steel undergoes a carefully controlled heat treatment, resulting in a fine martensitic structure with small carbides. This provides outstanding edge retention and long-lasting sharpness.
Corrosion resistance - The high chromium content ensures excellent corrosion resistance, essential for hygienic applications such as razors and medical instruments. Ideal for use in humid environments, such as bathrooms.
Custom solutions - We offer tailor-made dimensions and surface finishes, ensuring optimal performance for each specific application.
Applications of razor blade steel
Our blade steel is used in various types of razor blades, including:
- Disposable razor blades
- Multi-blade systems
- Razor blades for straight razors

Slitting
Wide strip is slit into finished sizes in special slitters with cemented carbide tools, which give a very high edge quality and extremely close tolerances. After slitting, a corrosion-preventive oil is applied to the strip.
Width tolerances
+/- 0.020 mm (0.0008 in.) for widths up to 20 mm (0.787 in.)
+/- 0.035 mm for widths over 20 mm (0.787 mm)
The variation within a coil is max. +/- 0.010 mm (0.0004 in.).
Delivery forms for Razor blade steel
To support diverse manufacturing processes, we offer razor blade steel in multiple formats:
Coils – Wound on plastic cores (Ø 280 mm / 11 in.) for continuous production with minimal handling. Available in 1-5 kg/mm strip width, with an outer diameter of 500-1000 mm (20-40 in.).
Bundles – Long, welded strips on paper cores (Ø 305 mm / 12 in.) with high-strength welds and precise tolerances. Maximum weight: 300 kg (660 lbs).
Strips – Cut-to-length options for specific applications and smaller production runs.
All formats are carefully packed according to customer requirements, destination, and transport method.
