Tensile elastic properties of 18:8 chromium-nickel steel as affected by plastic deformation
A 1939 NASA technical report on tensile elastic properties of 18:8 chromium-nickel steel after plastic deformation, presented as engineering test data for metallurgists and structural engineers. Its two pictures are dense graphs of proof stress against prior extension and stress-strain curves, with many plotted points, jagged connecting lines, and tick-marked axes in a plain black-and-white technical style that a designer could use for scientific chart backgrounds or data-visualization texture.
