General Product Description

Toolox® 44 is a steel already heat treated to the final properties.Thus saving time, costs and risks associated with heat treatment.

The very high strength is combined with a high and guaranteed toughness as well as an excellent fatigue resistence. Making Toolox® 44 the ideal choice for the most demanding engineering and mould and die applications.

Toolox® 44 can be surface hardened with methods like nitriding, laser and induction. Giving the possibilities to even further improve the performance.

Dimension Range

Toolox® 44 is available as plates in thicknesses between 0.236 - 5.118". Other dimensions can be available on request.
