Computerizing the Effect of Tempering on the Mechanical Properties of a Ni-Cr-Mo Steel.

Abstract

As part of an attempt to determine the optimum tempering cycle for gun tubes, mechanical properties of an AISI 4337 modified steel, i.e. gun steel, were determined for various tempering cycles. Austenitization temperatures of 845 C (1553 F) and 955 C (1750 F) were used, with tempering temperatures ranging from 425 C (797 F) to 595 C (1103 F) and tempering times ranging from 15 minutes to 240 minutes. This format, which allows the selection of tempering parameters from one plot to achieve desired properties, was developed. The mechanical property results for the material austenitized at 845 C are presented in the form of three dimensional plots and contour maps which interrelate the mechanical property of interest and tempering temperature and time. Examples showing the use of the plots are presented. (Author)
