Toolox44 is a pre-hardened steel with a hardness of 45 HRC and a yield strength of 1300 N/mm². It is easy to work with suitable tools. Because of the low levels of internal stress, large sections may be machined without movement and stress relieving is neither necessary nor recommended. This steel which is used in mechanical engineering and tool making may be polished and etched with excellent results.
