The pre-hardened, exceptionally clean tool and engineering steel.
Thanks to its low carbon and alloy content, Toolox® 33 is perfectly adaptable for welding as well as hot cutting. Giving the possibility to product components more cost efficient by saving machining time.
Toolox 33 is available as plates in thicknesses between 6.0 – 130.0 mm. Other dimensions can be available on request.
| Thickness (mm) | S Hardness (HBW) | Yield strength Rp0.2 (min MPa) | Tensile strength Rm (min MPa) | Elongation A5 (min %) |
|---|---|---|---|---|
| 6.0 – 130.0 | 275 – 325 | 700 | 800 | 10 |
Hardness is measured, according to EN ISO 6506-1, on a milled surface 0.5 – 2 mm below the plate surface.
| Thickness (mm) | Min impact energy for transversal testing, Charpy V 10×10 mm test specimen |
|---|---|
| 6.0 – 130.0 | 35 J / 20 °C |
1) Unless otherwise agreed, transverse impact testing according to EN 10025-6 option 30 will apply. For thicknesses between 6 – 11.9 mm, sub-size Charpy V-specimens are used. The specified minimum value is then proportrional to the cross-sectional area of the specimen compared to a full-size specimen (10 x 10 mm).
Ultrasonic inspection is carried out according to : EN 10 160 with extra demands according to specification.
More details are given in brochure Toolox® Guarantees and on www.toolox.com.
Tolerances according to Toolox® Thickness Guarantee.
Toolox® Guarantees meets the requirements of EN 10029 Class C but offers more narrow tolerances.
Tolerances according to EN 10029.
Tolerances are according to Toolox® Flatness Guarantees, which are more restrictive than EN 10029 Class N (steel type L).
According to EN 10163-2 Class B, Subclass 3.
Quenched and Tempered at a minimum temperature of 590 °C.
On delivery the plates meet the following specifications:

Welding, bending and machining
For information concerning welding and fabrication, see brochures on consult Tech Support.
Toolox® products is not intended for further heat treatment. If Toolox is heated above 590 °C after delivery no guarantees for the properties of the steel are given. Nitriding or surface coating may be carried out if the temperature is below 590 °C.
Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on the product. Grinding, especially of primer coated plates, may produce dust with high particle concentration.

Pre-hardened, precise, predictable steel, now in round bars.
Toolox® round bars are pre-hardened, ready-to-use quenched and tempered tool steels that come in a wide range of diameters from small to large.
Suitable for engineering applications in tool holders and in different types of shafts and rolls, the diameter dimensions also provide a better solution for round parts in tooling applications like molding and in dies for aluminium die casting.
Toolox 44 round bars is available in diameters 21.0 – 282.0 mm. Other dimensions can be available on request.
| Diameter (mm) | Hardness (HBW) |
|---|---|
| 21.0 – 282.0 | 410 – 475 |
Hardness is measured, according to EN ISO 6506-1, on a milled surface 0.5 – 2 mm below the plate surface. Bar hardness is measured on a milled surface, with indents positioned as impact test according to EN 10 083.
| Diameter (mm) | Hardness (HBW)Min. impact energy for longitudinal testing, Charpy V 10×10 mm test specimen |
|---|---|
| 21.0 – 141.0 | 410 – 475 |
Impact testing according to EN 10 083.
Ultrasonic inspection is carried out according to : EN 10 160 with extra demands according to specification.
Tolerances for Toolox® round bars are according to EN 10 060.
