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
