    General Information

    100Cr6 is a through hardening bearing steels intended for rolling contact and other high fatigue applications. In the hardened condition the high hardness, high strength and high cleanliness provides the steel with the right properties to withstand high cycle, high stress fatigue. 100Cr6 is mainly used for small and medium sized bearing components. It is also regularly used for other machine components that require high tensile strength and high hardness. The hardenability approximately corresponds to a ring with max. 17 mm wall thickness.

    Variant 5620 is offered as 803F or 100Cr6

    This steel is delivered in a number of variants. The most common are listed below.

    IQ-Steel®
    803Q  -  Isotropic properties and better fatigue strength due to higher cleanliness levels, and a finer size and distribution of non-metallic inclusions

    BQ-Steel®
    803Z  -  Improved cold forming properties due to the reduced silicon content
    803D  -  Improved machinability due to the higher sulphur content.
    803P  -   With a reduced sulphur content to reduce the number of sulphide inclusions
    803A  -  With a reduced controlled sulphur content to reduce the number of sulphide inclusions but ensure consistent machinability
    803F  -   With a controlled sulphur content for consistent machining properties
    803N  -   Slightly increased carbon range to meet the requirements of some international standards
    803J   -   Standard

    5620 -  A continuous cast variant of 100Cr6

    IQ-Steel® 

    IQ-Steel® is an isotropic quality ultra clean steel optimized for high fatigue strength under multi axial loading.

    BQ-Steel® 

    BQ-steel® is a bearing quality clean steel optimized for fatigue strength and is also ideal for new design solutions outside the bearing industry.
