Toolox 44 - Quenched and tempered up to 419 BHN (45HRC)

What kind of steel is the Toolox 44?

Toolox 44 comes with a lot of plus points like the very low residual stresses, high impact toughness and fatigue resistance. Due to its low carbon and alloy content, this tool steel material is suitable for both welding and thermal-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.

Toolox 44 General Information

Where can Toolox 44 be used?

With its high strength, good toughness and good mechanical properties, Toolox 44 can be used in many industries. Toolox 44 can be used in engineering and tooling due to its wear resistance, durability, dimensional stability (as well under high temperatures) and toughness for molds, die casting, stamping and forging. Due to its surface hardness, impact strength and wear resistance it can be used for machine components like bearings, cylinders, pins and bushings. The former properties make the Toolox 44 useful for mining equipment, wear plates, pump parts, wind turbines, gears and armor plates as well as shredders and for manufacturing agricultural equipment like plough sheares.

Is Toolox 44 a stainless steel?

No, Toolox 44 is not a stainless steel.

Is Toolox 44 corrosion resistant?

Toolox 44 is not a corrosion resistant steel. To be classified as a corrosion resistant steel it has to have a mass fraction of 10.5% of carbon. The Toolox 44 has a mass fraction of approx. 1.35%. 

Is  Toolox 44 magnetizable?

As a ferrous based material the Toolox 44 is magnetizable.

Heat treatment Toolox 44

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

Any further heat treatment of this steel grade has to be considered very well to preserve the given properties of this grade by the manufacturer. To preserve those properties one has to have a detailed understanding of the metallurgy of the Toolox 44 and how the heating process may change its properties.

Tempering Toolox 44

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

Dimensional changes Toolox 44

Toolox 44 is made for dimensional stability after machining but may still experience dimensional changes when for example welding due to rapid heat changes.


Toolox 44 Electrical Discharge Machining (EDM)

Selecting the correct process, finishing requirements, power input as well as electrodes and dielectric fluid is important for any steel. As Toolox 44 is produced to have certain properties, it is very important to ensure that the process is planned and controlled to maintain the intrinsic properties and to meet the specifications of the intended application.

Toolox 44 surface treatment

For applications needing better surface properties, Toolox 33 can be induction or laser hardened and nitrited. This gives Toolox 44 a high surface hardness with a very resistant core, increased fatigue resistance and therefore a longer service life.

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

Induction hardening Toolox 44

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 Toolox 44

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.

Nitriding Toolox 44

Nitriding Toolox 33, can reach a surface hardness of 572 - 711 HBN (58 - 65 HRC), is used when high wear resistance is needed for a longer service life. If PVD (Physical Vapor Deposition) coating, the nitrided 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).

Machinability Toolox 44

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

Welding Toolox 44

Toolox 44 can be welded by all conventional methods and can be joined to any other kinds of weldable steels. Before welding the base metal should be cleaned from contaminants such as grease, rust, oil and moisture and sharp edges removed. Consumables suitable for Toolox are stainless, unalloyed, and low-alloyed consumables. 

Toolox 44 wear resistance

Toolox 44 has a wear resistance of 4 on a scale where 1 is low and 6 is high.

Toolox 44 tensile strength

Toolox 44 has a tensile strength of approx. 205.9 KSI on delivery (0.145 KSI = 1MPa). In order to reach this value, a tensile test is performed to show how much force is needed to stretch or elongate a sample before it breaks.

Toolox 44 yield strength

The yield strength shows how much stress can be applied to a material before it plastically deforms. Beyond that point the material will not return to its original form if the stresses are taken away but will stay deformed or even break.

The yield strength for Toolox 44 is 189 KSI (1300 MPa).

Working hardness Toolox 44

The working hardness for the Toolox 44, on delivery, 419 BHN (45 HRC)

Toolox 44 Steel Properties

Toolox 44 cold work

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.

Toolox 44 thermal conductivity

The heat conductivity for Toolox 44 is at 28.0 W/(m*K) (194 BTU/(h-ft*°F)) at room temperature.

Toolox 44 thermal expansion coefficient

The thermal expansion coefficient shows how much Toolox 44 might expand or contract when the temperature is changed. This is very important information, especially when working with high temperatures, or where there are strong temperature changes during applications. The thermal expansion coefficient is typically in the region of approx. 13.5 10-6m/(m*K) at room temperature. 

Is Toolox 44 a knife steel?

Toolox 44 has good wear resistance which lets this material hold an edge, it has good toughness preventing chipping and breaking under stress and has been produced to have good dimensional stability which is vital in maintaining precise tolerances during machining but though it has some corrosion resistance it does not have enough to be used in corrosive environments.

Conclusion

Quenched and tempered material may streamline the manufacturing process and costs, Toolox 44 also comes with properties like good wear resistance, good dimensional stability and good machinability that make machining this material grade a good choice for a lot of applications needing accurate dimensions and tolerances, durable performance in abrasive environments with a good balance between wear resistance and manufacturing ease.
