E185

    Product Description

    The newly developed, patent pending, BÖHLER E185 AMPO is an AM powder, fulfilling the highest demands from various industries, ranging from motorsport to engineering components and any kind of prototype applications. This low alloyed steel with easy printability and the possibility for surface treatments (e.g. case hardening or nitriding) was developed especially for the demands of the 3D printing industry. The material shows an excellent combination of strength and toughness.

    Property Features

    Particle size distribution 15 – 45 µm:
    D10[µm]                            18 – 24
    D50[µm]                            29 – 35
