Sep 05, 2017 · Yield strength is a measurement of how well a steel material can hold up to stress. Through mathematical formulas and testing, metal professionals calculate the amount of stress that is necessary to cause the metal to deform. In the case of steel, high yield steel will hold up to stress and pressure better than low yield steel.
