Abstract : DESCRIPTORS: *Steel, *Melting, Vacuum appara tus, Air, Vacuum furnaces, Electric arcs, Electrodes, Gases, Heat treatment, Mechanical properties, Tensile properties, Forging, Tests, Tables, Statistical data, Aircraft, Materials, Processing. Identifiers: H-11 steel. The Phase II analysis of tansverse strength and ductility at the 280 to 300 ksi and 300 ksi minimum strength levels established that strengthAND DUCTILITY TEND TO DECREASE WITH INCREASING BILLET SIZE, THAT SURFACE SPECIMENS EXHIBIT THE MOST FAVORABLE PROPERTIES, THAT CONSUMABLE ELECTRODE VACUUM REMELTED STEEL IS UNQUESTIONABLY SUPERIOR TO EITHER ELECTRIC FURNACE AIR MELTED OR AIR MELTED-VACUUM DEGASSED STEEL, AND THAT THERE EXISTS CONSIDERABLE VARIATION IN PROPERTIES BETWEEN MILLS FOR A GIVEN BILLET SIZE AND BETWEEN BILLET SIZES OF A GIVEN MILL.
