BU GREY CI continuous cast bars consist of a uniform partial pearlitic structure from the bar surface to the core. This material is ideally suited to high speed machining with
significant improvements in cutting tool life and reductions in drill wander which occurs when the drill point gravitates to a softer surface. Grade has a typical fine grain size of 7-8 in dense homogeneous matrix. These properties ensure its suitability in applications demanding the ability to withstand high pressures without leaking.
