Product Description

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.

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.
