The basic hardness of 45 HRc is the right one for many tools. If this is not enough
for you, the Toolox 44 nitrided tool steel comes
Toolox tool steel is hard and solid enough to form a perfect
substrate for surface treatment. If you choose nitride, you can achieve surfacehardnesses of 58-65 HRC for
extremely wear-resistant applications. Or you can coat the steel to resist
corrosive attacks – depending on the
corrosive medium – while maintaining the super-tough core strength that can
prevent splinter and crack formation.
Fields of application are forming tools for sheet metal
forming and machine components.High
hardness and toughness
These features make Toolox a
perfect substrate for nitriding, opening up a wide range of applications
that require high resistance to surface pressure and wear.
The low carbon content and the very high
cooling rate ensure that Toolox steel is two to three times tougher than
comparable steels with a similar hardness.
Surface treatments such as nitriding and
PVD coating require high toughness. A tiny scratch in the surface layer will probably not spread into the substrate.
