Toolox® Engineering & Tool steel

Toolox® is engineering and tool steel delivered in quenched and tempered condition. Due to high hardness at the time of delivery, Toolox® is ready to use without additional heat treatment. Extreme steel cleanliness as well as strictly controlled alloying gives incredible mechanical and utility properties. Toolox® has high hardness but is easy to machine and it keeps dimensional stability like no other steel. Toolox® has heat resistance up to 590°C and can be nitrided as well as PVD-coated in order to increase surface hardness.

The main purpose of using Toolox® is to decrease costs. Parts made of Toolox® will have increased lifetime and can be produced faster with less processing in comparison with conventional steels for heat treatment. Toolox® is the best choice for tooling and engineering applications working in temperatures up to 590°C.

Toolox® is also available as round bars.
