Cold-rolled steel strip Alleima® 13C26

stainless steel

Razor blade strip steel in Alleima® 13C26 martensitic stainless chromium steel delivered as cold-rolled strip steel with close dimensional tolerances and high accuracy on flatness and straightness. Combined with excellent metallurgical properties, our razor blade steel contributes to efficient razor blade production and high-quality razor blades. Our razor blade steel characteristics Low content of non-metallic inclusions Smooth dull surface Very close tolerances and high accuracy on flatness and straightness Good blanking and hardening properties Good grinding and honing properties 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 Our razor blade strip steel can be supplied in coils or bundles, both carefully packed with various packing materials according to customer requirements, destination or method of transport. Coils The razor blade strip steel is wound into pancake coils on plastic cores with an inner diameter of 280 mm (11.0 in.). The coils can be supplied in weights between 1 and 5 kg/mm strip width which means an outer diameter from about 500 to 1000 mm (20-40 in.). Bundles The razor blade strip steel is welded into a long, continuous length, which is wound on a paper core with an inner diameter of 305 mm (12.0 in.).
