The prehardened steel for extrusion dies and engineering components
Toolox® 44 prehardened steel is suitable for extrusion dies and engineering components that require high strength. It possesses good workshop properties.
Toolox® 44 is a prehardened engineering and tool steel. Despite its high hardness, Toolox® 44 combines very good machinability with dimensional stability during machining.
Its nominal 450 HBW/45 HRC hardness makes Toolox® 44 your ideal choice for demanding mold and die applications. The high steel cleanliness gives Toolox® 44 very good polishing, A2 gloss, and texturing capabilities.
In applications that demand additional surface hardness to counteract wear, you can nitride and PVD coat Toolox® 44 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).
