Non-alloyed tool steels

Non-alloyed tool steels have a carbon content of between 0.5 and 1.5 % and often contain small amounts of tungsten. For example, non-alloyed tool steels are used in plug tools for pneumatic hammers which are used in the field of mining and road construction (drill bit steel).

Non-alloyed tool steels are cold-working steels and as such, they are not suitable for operating temperatures above 200°C. Due to the lack of alloy, they are cheaper to produce, however compared to alloyed tool steels, they cannot be fully hardened. Unalloyed tool steel is therefore somewhat more susceptible to wear and is not designed for very high mechanical stress. Non-alloyed tool steel is therefore somewhat more susceptible to wear and is not designed for very high mechanical stress.

Die Wilhelm Jungermann GmbH supplies its customers with non-alloyed tool steel / drill bit steel (material C 70 W2) for pneumatic plug tools.
