440HBW hardening high strength tool and engineering steel plate for offshore
Description
The pre-hardened steel for extrusion dies and engineering components.
440HBW pre-hardened steel is suitable for extrusion dies and engineering components that require high strength. It possesses good workshop properties.
440HBW tool steel is a pre-hardened engineering and tool steel. Despite its high hardness, 440HBW tool steel combines very good machinability with dimensional stability during machining.
Its nominal 450 HBW/45 HRC hardness makes 440HBW tool steel your ideal choice for demanding mold and die applications. The high steel cleanliness gives 440HBW tool steel very good polishing, A2 gloss, and texturing capabilities.
In applications that demand additional surface hardness to counteract wear, you can nitride and PVD coat 440HBW tool steel to customize the mold or die properties. Surface engineering can be carried out as long as the deposition temperature does not exceed 590°C (1,094°F).
Dimension Range
440HBW tool steel is available as plates in thicknesses between 6 - 130 mm. Other dimensions can be available on request.
Mechanical Properties
| Thickness (mm) | Hardness (1) (HBW) |
| 6- 130 | 410- 475 |
(1) Hardness is measured, according to EN ISO 6506-1, on a milled surface 0.5 - 2 mm below the plate surface.
Impact Properties
| Test temperature | Min. impact energy, Charpy-V, transverse direction (2) J |
| 20 °C | 18 |
(2) Impact testing according to EN 10025, EN ISO 148.
Ultrasonic testing
Ultrasonic inspection is carried out according to EN 10160
Thickness
Tolerances according to the requirements of EN 10029 Class C
Length and Width
Tolerances according to EN 10029.
Flatness
Flatness tolerances are according to EN 10029 Class N (steel type L).
Surface Properties
Surface properties of 440HBW tool steel are according to EN 10163-2 Class B, Subclass 3.
Delivery Conditions
Quenched and Tempered at a minimum temperature of 590 °C.
On delivery from VANFORGE the plates meet the following specifications:
• free from mill scale
• not repair welded
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.
