Product Details
330HBW hardened tool and engineering steel round bar
Description
Pre-hardened, precise, predictable steel, now in round bars
330HBW tool steel 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
330HBW tool steel round bars are available in diameters 21 - 141 mm. Other dimensions can be available on request.
Mechanical Properties
Diameter (mm) | Hardness (HBW) |
| 21 - 141 | 275 - 325 |
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 10083.
Impact Properties
| Test temperature | Impact energy, Charpy-V, Min J |
| 20 °C | 35 min J |
Impact testing according to EN 10083.
Ultrasonic testing
Ultrasonic inspection is carried out according to EN 10308.
Diameter and Length
Tolerances according to EN 10060.
Straightness
Straightness according to EN 10060.
Surface Properties
Peeled surface.
Delivery Conditions

Fabrication and Other Recommendations
Welding, bending and machining
330HBW tool steel is not intended for further heat treatment. If 330HBW 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.
