      Mechanical properties of steel


      Mechanical properties are often referred to as elasticity, plasticity, stiffness, aging sensitivity, strength, hardness, impact toughness, fatigue strength and fracture toughness.

      Elasticity: the deformation of a metal material under external force and the ability to regain its original shape when taken out of an external force.

      Plasticity: the ability of a metal material to produce permanent deformation without causing damage when subjected to external force.

      Stiffness: the ability of metal materials to resist elastic deformation when subjected to force.

      Strength: the ability of metal materials to resist plastic deformation and fracture under external force.

      Hardness: the ability of metal materials to resist stiffer objects pressed into them.

      Impact toughness: the ability of metal materials to resist fracture under impact loading.

      Fatigue strength: the maximum stress that occurs when a metal material is subjected to numerous repeated or alternating loads without causing fracture.

      Fracture toughness: the performance index used to reflect the material's ability to resist crack expansion
