Toolox 44 - pre-hardened engineering and tool steel with a nominal hardness of 450 HBW/45 HRC. 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 an ideal choice for demanding mould/die applications. The high steel cleanliness gives Toolox 44 very good polishing, A2 gloss, and texturing capabilities.
In applications where further increased surface hardness is required counteract wear can Toolox 44 be of nitrided/PVD-coated to tailor-make mould/die properties. Surface engineering can be carried out as long as the deposition temperature is kept below 590 °C.
