This document summarizes a lecture on final finishing operations in steel making. The lecturer discusses how final finishing is used to generate desired mechanical properties for different applications. Properties like strength, ductility, and hardness are targeted. The lecturer explains that microstructure analysis reveals the phases present in steel, and the type, size, and distribution of phases determine the material properties. Different phases in iron-carbon steel like spheroidite, pearlite, bainite and martensite result in varying hardness, strength and ductility. Final finishing manipulates microstructure to develop the required properties for a given use.
