Question: aisi 4340 steel specimens are tested using astm e10 standards...

Question details

AISI 4340 steel specimens are tested using ASTM E10 standards to determine the Brinell Hardness of the material. The following table outlines the data collected for AISI 4340 annealed and normalized steel. Estimate the values of S and Sy for both treatments using the average hardness. How do these values compare to the given tensile and yield strengths listed in Appendix C-4a? Annealed Hardness (Bhn) 210 220 218 Normalized imen 1 imen 2 imen 3 imen 1 imen 2 imen 3 Hardness (Bhn) 360 365 364
