Features:
- Despite
hardness of nominal 45 HRC, this
new steel is easy to
machine.
- Particularly
suitable for manufacturing
plastic molds because it can be
polished and etched with very
good results.
- Great
for guide rails, bending tools,
etc. when high stability materials
are required.

Toolox 44 is a new
quenched and tempered steel designed to have high
impact resistance and low residual stresses and
therefore good dimensional stability. Despite a
hardness of 45 HRC, the new steel is easily
machined. Toolox 44 is particularly suitable for
manufacturing plastic molds because it can be
polished and etched with very good results. Fields
of application: plastic molds, rubber molds, wear
components and machine components, such as guide
rails, bending tools, etc., where stability
materials are required.

can be machined on conventional machines. It is
important that sharp tools are used with a
positive cutting angle and that vibration is
avoided. Use the following recommendations as
guidelines and the starting point for your own
evaluation of best practice.
