Tensile and compressive properties of some stainless-steel sheets

Abstract

Tensile and compressive tests were made on specimens from chromium-nickel (17-7 and 18-7) stainless-steel sheets, with cold-reductions from zero percent (annealed) to 50 percent, and thicknesses from 0.01 to 0.06 in. The tensile yield strengths ranged from 34 to 200 kips/in2. The effect of a stress-relieving treatment at 300 0 C for 24 hours was investigated for one of the compositions. The tensile tests were made on standard specimens. The compressive tests were made by the pack method developed at the National Bureau of Standards and by the cylinder method developed by Russell Franks, of the Union Carbide & Carbon Research Laboratories. Tests were made on both longitudinal and transverse specimens from each sheet. The results are given in tables and stress-strain curves to facilitate application in the design of lightweight structures from these materials. The effect of the degree of cold-reduction and of the stress-relieving treatment on the shape of the stress-strain curves and on the tensile and compressive properties is discussed.
