440HBW quenched and tempered tool and engineering steel round bar
Description
Pre-hardened, precise, predictable steel, now in round bars.
440HBW tool steel round bars are pre-hardened, ready-to-use quenched and tempered tool steels that come in a 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
440HBW tool steel round bars are available in diameters 21 - 172 mm. Other dimensions can be available on request.
Mechanical Properties
| Diameter (mm) | Hardness (HBW) |
| 21 - 150 | 410 - 475 |
Bar Hardness is measured on a milled surface, with indents positioned as impact test according to EN 10083.
Impact Properties
| Diameter (mm)
| Min. Impact Energy for Charpy-V, longitudinal direction |
| 21 - 141 | 18 J / 20 °C |
| 142 - 150 | 11 J / 20 °C |

Fabrication and Other Recommendations
Welding, bending and machining
440HBW tool steel is not intended for further heat treatment. If 440HBW tool steel is heated above 590°C after delivery from VANFORGE, 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.
