BÖHLER E185


The low alloy BÖHLER E185 steel is designed for components to be used in particularly demanding sectors such as motorsport, automotive, earthmoving machinery and precision mechanics. The low carbon content facilitates moulding and can be used for both final elements and prototypes.

Thanks to its chemical composition, it is also the first steel specifically designed for the production of 3D printing components that undergo classic thermochemical treatments, such as case hardening, nitriding and carbonitriding.

BÖHLER E185 is therefore the ideal material for the production, by means of 3D printing with metals, of components for transmission parts such as gears, pinions, pins, crowns, shafts, synchronisers and bevel gears.
