Toolox® 33
General Product Description
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.
Dimension Range
Toolox 33 is available as plates in thicknesses between 6.0 – 130.0 mm. Other dimensions can be available on request.
Mechanical Properties
| 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.
Impact Properties

Delivery Conditions
Quenched and Tempered at a minimum temperature of 590 °C.
On delivery from SSAB the plates meet the following specifications:
- Free from mill scale
- Not repair welded
Delivery requirements can be found in SSAB’s brochure Toolox Guarantees or at www.toolox.com.
Fabrication and Other Recommendations
Welding, bending and machining
For information concerning welding and fabrication, see SSAB’s brochures on www.ssab.com or consult Tech Support.
Toolox® products is not intended for further heat treatment. If Toolox is heated above 590 °C after delivery from SSAB 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.

Toolox® 44 round bars
General Product Description
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.
Dimension Range
Toolox 44 round bars is available in diameters 21.0 – 282.0 mm. Other dimensions can be available on request.
Mechanical Properties
| 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.
Impact Properties
| 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 Testing
Ultrasonic inspection is carried out according to : EN 10 160 with extra demands according to specification SSAB V6.
Tolerances
Tolerances for Toolox® round bars are according to EN 10 060.
