High Speed Steels

High-speed steel offers high wear resistance. M-2 high speed steel provides six to ten times more wear than conventional blade steel, while M-4 is three times more durable than M-2. High-speed steel also has excellent temper resistance, holding hardness even when exposed to temperatures up to 1,000 ° F.

We now make razor blades from M-2 High Speed Steel for increased performance vs carbon or stainless blades - more information on our Industrial Razor Blades

We have also recently introduced the most wear resistant steel blade available for paper, foil, and film slitting - more for information on our Industrial Razor Blades
