This report discusses the various aspects related to the tensile properties in plates and forgings, including the feasibility of using guaranteed tensile values that exceed the specified minimum tensile strength in the material specifications, and provides recommendations for design stresses and Code construction based on the higher guaranteed tensile and yield strength values. The issues discussed in this report apply mainly to tensile strength values higher than the minimum specification values since the tensile strength generally governs the Code allowable stresses for carbon and low alloy steels for ASME Section VIII, Div 1 construction.
