Tensile Strength Rm

Tensile Strength Rm

The tensile strength Rm indicates the limit, at which the steel tears under pressure, thus it’s maximum tensile stress. The tensile strength is determined by the tensile test. The tensile strength is denominated with the abbreviation Rm. It is calculated with the quotient of maximum tensile force and the initial diameter of the sample (N/mm2). It is the maximum of the stress-strain-curve.
