    Abstract

    The quality of nails may be measured by the assessment of their impact bend angle, flexural yield strength, or hardness. Testing for the determination of these criteria as conducted by White, McLain, and Padla [1] is based on three factors carbon content (denoted by SAE number), nominal shank diameter, and hardening. The factorial analysis of their experimental results is presented in this paper Given the nonlinear variation of the flexural yield strength versus the carbon content [1], our analysis is divided into two blocks (1) a low-carbon region, between SAE 1010 and SAE 1022 and (2) a high-carbon region, between SAE 1022 and SAE 1040 The impact of main effects and multiple-factor interactions on each criterion is explored in each block. Results show the SAE class to be a valid indicator of the flexural yield strength in both the low- and highcarbon regions. However, hardening must be taken into consideration as another effective factor when the carbon content is high.
