CORRELATION OF TENSILE PROPERTIES OF STEEL CASTINGS AND MATERIAL IMPERFECTIONS AS DETERMINED BY RADIOGRAPHY.
Abstract
The relationships between tensile properties of 410 stainless-steel castings and imperfections, as determined by radiography, were investigated. The purpose was to establish confidence in a system of evaluating castings by radiographic inspection. Tensile properties investigated were: tensile yield, tensile ultimate, elongation and modulus of elasticity; imperfections were: gas holes, inclusions and porosity; thicknesses were: 0.1, 0.2, 0.3, and 0.6 in. Test specimens were heat treated to a 180,000 to 200,000 psi. Statistical analysis of test results is presented. Relationships between tensile properties and size or intensity of imperfections are represented in tables and graphs. (Author)
