Toolox 44 General Information

Toolox 44 comes with a lot of plus points like the very low residual stresses, high impact toughness and fatigue resistance. Due to the low carbon and alloy content this material is suitable for both welding and thermos-cutting. With the ability to nitrate this material the surface hardness can be additionally increased and service life extended. The combination of those characteristics makes Toolox 44 suitable for demanding engineering and is especially suited for plastic molds as it has excellent polishing and photo-etching properties due to the cleanliness of the material.


Heat treatment

Further heat treatment for this steel grade is not intended as it comes in a quenched and tempered condition.


Tempering

Toolox is tempered (delivery condition) at 1094°F (590°C), this removes all residual stresses and allows excellent precision when machining.


Cold working

With the combination of high strength, fatigue resistance and toughness, Toolox is used in cold work for forming, bending and drawing but also finds its uses in components like guide plates, support plates and staple holder plates.


Machinability

Toolox 44 is easy to machine and has a very good dimensional stability.


Welding

Toolox can be welded by all conventional methods and can be joint to any other kinds of weldable steels. Before welding the base metal should be cleaned from contaminations such as grease, rust, oil and moisture and sharp edges removed. Consumables suitable for Toolox are stainless, unalloyed and low-alloyed consumables.


Surface treatment


Induction or laser hardening and nitriding

For applications needing better surface properties, Toolox can be induction or laser hardened and nitrited. This gives Toolox a high surface hardness with a very resistant core, increased fatigue resistance and therefore a longer service life.

Induction hardening, as well as with the other surface hardening processes, will increase the surface properties further. Induction hardening is a very common method to increase the surface hardness with a relatively large thickness.

Laser hardening has the added advantage of a very smooth surface which reduces friction and the risk of material sticking to the surface. To increase the surface hardness while laser hardening the material, a carbon powder is put on the surface.

Nitrating Toolox, it can reach a surface hardness of 572-711HBN (58-65HRC), is used when high wear resistance is needed for a longer service life. If PVD coating the nitrated surface, an even higher surface hardness as well as a corrosion resistance can be reached. Toolox 44 can reach a surface hardening of 800 HV with this procedure and a hardening depth of 1/64 to 5/64 inches (0.2 to 2mm).

Note: Any surface treatment should not exceed the temperature of 1094°F (590°C).
