What is the yield force of steel?

The yield force of steel refers to the amount of stress at which the material begins to deform plastically, meaning it will not return to its original shape after the load is removed. This value is typically measured in megapascals (MPa) or pounds per square inch (psi) and can vary depending on the type of steel; for example, structural steel generally has a yield strength ranging from about 250 MPa to 400 MPa. The specific yield strength can depend on factors such as the steel's composition, heat treatment, and processing methods.
