Toolox 33 Engineering and Tool Steel - Quenched and tempered
What kind of steel is Toolox 33?
Toolox 33 comes with a lot of plus points like the very low residual stresses, high impact toughness and crack resistance. Due to the low carbon and alloy content this tool steel 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 33 suitable for construction and wear parts and other mechanical components as well as plastic and rubber injection molds. It may also be polished and etched with exceptional results.On this Page

Toolox 33 General Information
Where can Toolox 33 be used?
With its high strength, good toughness and good mechanical properties, Toolox 33 can be used in many industries. Toolox 33 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 33 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 33 a stainless steel?
No, Toolox 33 is not a stainless steel.Is Toolox 33 corrosion resistant?
No, Toolox 33 is not corrosion resistant. To be corrosion resistant a steel needs to have a mass fraction of a minimum of 10.5% chromium to be classed stainless steel and therefore be corrosion resistant.Is Toolox 33 magnetizable?
As a ferrous based material the Toolox 33 is magnetizable and suitable for magnetic clamping.Toolox 33 heat treatment
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 33 and how the heating process may change its properties.
Tempering Toolox 33
Toolox 33 is tempered (delivery condition) at 1094°F (590°C), this removes all residual stresses and allows excellent precision when machining.Dimensional changes of the Toolox 33
Toolox 33 is made for dimensional stability after machining but may still experience dimensional changes when for example welding due to rapid heat changes.Electrical Discharge Machining (EDM) for Toolox 33
Selecting the correct process, finishing requirements, power input as well as electrodes and dielectric fluid is important for any steel. As Toolox 33 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 33 surface treatment
For applications needing better surface properties, Toolox 33 can be induction or laser hardened and nitrited. This gives Toolox 33 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 33
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 33
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 33
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 33 can reach a surface hardening of 700 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).
Machinability of Toolox 33
Welding Toolox 33
Toolox 33 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 33 wear resistance
The wear resistance for Toolox 33 is 3 on a scale where 1 is low and 6 is high.Toolox 33 tensile strength
The tensile strength for Toolox 33 is approx. 163.1 KSI (0.145KSI = 1MPa). This value is the result from a tensile test to show how much force is needed before the material starts to stretch or elongate before it breaks.Yield strength Toolox 33
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 33 is 123 KSI (850 MPa).
Toolox 33 working hardness
The working hardness for the Toolox 33, on delivery and without nitriding, 277 - 331 BHN (30 - 36 HRC)Steel Properties for Toolox 33
Cold work Toolox 33
With the combination of high strength, fatigue resistance and toughness, Toolox 33 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 33 thermal conductivity
The heat conductivity for Toolox 33 is at 35.0 W/(m*K) (243 BTU/(h-ft*°F)) at room temperature.
Value | By temperature |
---|---|
35.0 | 68 °F |
35.0 | 392°F |
30.0 | 572°F |
23.0 | 1112°F |
Thermal expansion coefficient Toolox 33
The thermal expansion coefficient shows how much the Toolox 33 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. 13.1 10-6m/(m • K) at room temperature.Is Toolox 33 a knife steel?
Toolox 33 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 33 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.Datasheet Toolox 33
