Yield
The ratio of the quantity of finished shipments to the total raw steel produced, adjusted for changes in inventory and any slabs that are purchased from outside. Yield has significantly improved during the past decade, primarily as the result of the industry's conversion to continually cast steel, whose yield is superior to that of traditional ingot teeming.

Yield Point
The stress in a material at which there occurs a marked increase in strain without an increase in stress during tensile testing.

Yield Point Elongation
The amount of strain that is required to complete the yielding process. It is measured from the onset of yielding to the beginning of strain hardening.

Yield Strength
The stress at which a material exhibits a specified limiting deviation from the proportionality of stress to strain during tensile testing.

Yield Stress
The stress level of highly ductile materials, such as structural steels, at which large strains take place without further increase in stress.
