What Is the Yield Strength of Mild Steel?

The yield strength of mild steel is 248 megapascal. Yield strength is the stress at which a material has undergone an arbitrarily selected amount of deformation, often 0.2 percent.

This indicates that when the stress applied on mild steel is 248 megapascal, it shows a measurable amount of deformation, that is, 0.2 percent.The main purpose of yield strength is to describe and define the stress at which plastic deformation begins in a material, such as mild steel.
