[Mechanical Performance Terms] Tensile Strength (σb)

During the tensile process, the maximum force (Fb) that the sample is subjected to during breaking is the stress (σ) obtained from the original cross-sectional area (So) of the sample, which is called the tensile strength (σb). The unit is N / mm2 (MPa). It indicates the maximum ability of a metal material to resist damage under the action of tension. The calculation formula is: In the formula: Fb-the maximum force that the sample is subjected to when breaking, N (Newton); So-the original cross-section area of the sample, mm2
