Abstract : This revised sheet quality 'specification' differs from MAB-184-M (report of the Subpanel on Quality Specifications) in that it is limited to tungsten, and includes tensile property minimum values. These tensile minimums reflect realistic producer capabilities and as such should be of particular interest to aerospace weapons designers. These quality standards apply in general to sheet which is to be used in the as-furnished condition. Quality sampling specifications for plate, such as would be used in shear spinning, are covered in another publication (MAB-190-M). Sheet destined for drastic working operations, such as cupping or drawing, might require a different microstructure (retaining a greater capacity for additional deformation) than that corresponding to the material in this report.
