General Product Description

The pre-hardened, exceptionally clean engineering and tool steel.

Toolox® 40 is a pre-hardened steel suitable for engineering components and mold applications. It possesses good dimensional stability after machining.

Toolox® 40 features the same machinability as the conventional P20/W.Nr 1.2311 steel, despite its nearly 100 HBW higher nominal hardness, in combination with the renowned high dimensional stability of Toolox®. This makes Toolox® 40 your ideal choice in engineering components that require higher strength, or in molds and dies that demand higher wear resistance.

Dimension Range

Toolox® 40 is available as plates in thicknesses between 6.0 - 130.0 mm. Other dimensions can be available on request.
