Approximate quantitative relationships between mechanical properties of structural steel

  • Published:
Metal Science and Heat Treatment Aims and scope

Summary

  1. 1.

    The strength, ductility, and impact strength of structural steel are interrelated not only qualitatively but also quantitatively.

  2. 2.

    The interdependence characteristic K is represented by a hyperbola; whena H > 6 kgm/cm2 this relationship is close to a linear relationship. In many cases it is close to a constant value K=150 whena H ≈ 10 kgm/cm2.

  3. 3.

    Cold brittleness and some other embrittlement factors do not disagree with this relationship because the dependence K = σbδ5/a H retains the shape of a hyperbola in this case also. For a specific steel this dependence can be expressed in terms of σT and Ψ, using the relationships σT/σb and Ψ/δ
