Ruling section of forged shaft

2001

-What is the physical significance of 'ruling section' in case of hardening and tempering of carbon steel.

-In case the diameter of cross section of a forged carbon steel (0.5c and 0.75Mn) shaft under hardening and tempering condition made more than the specified 'ruling section' for the range of UTS,YS,%EL and hardness then how the sample to be taken from actual forged shaft for assessment of representative properties?

"More accurately termed limiting ruling section. One of the most important factors associated with the choice of steel for a given purpose is to ensure that the desired mechanical properties are obtained throughout the section when the material has been heat treated. The limiting ruling section determines the maximum diameter or cross-section of a bar or component in which the specified properties can be achieved by a given heat treatment. The analysis of the steel also has an important bearing on this."
