  • The tensile strength of a steel grade is the stress, expressed in N/mm² (MPa), at which the material collapses/breaks.

    To determine the tensile strength of a particular grade of steel, a normalised tensile test is carried out. With this, a diagram is recorded showing the tension on the vertical axis and the elongation on the horizontal axis. In the practice of designing and strength calculations of structures and components, the yield strength is used rather than the tensile strength.
