THE EFFECT OF SHEET THICKNESS ON THE TOUGHNESS OF 18-9-5 MARAGING STEEL,
Abstract
A study was made to determine the effect of sheet thickness on the toughness of an 18-9-5 maraging steel. To date, a large amount of data has been generated on the toughness of this type material, particularly in thicker sections, but very little has been accumulated for a range of sheet thicknesses. The material was examined in thicknesses ranging from 0.020 to 0.120 in.. To study the toughness of this material, the notched-tosmooth tensile test was used. Notch properties were obtained at room temperature and at 60 F. For this heat of steel, there is a noticeable degrading effect on the toughness at thicknesses of 0.080 in. or greater for three different maraging conditions. Low temperatures have only a slight degrading effect on the toughness of this material over the range of thicknesses examined. (Author)
