The main mechanical properties are elasticity, plasticity, stiffness, aging sensitivity, strength, hardness, impact toughness, fatigue strength and fracture toughness.
Elasticity: Metal material deforms when it is subjected to external force. When the external force is removed, it can restore its original shape.
Plasticity: The ability of ASTM A570 Grade 30 ASTM A570/A570M to produce permanent deformation without causing damage under external forces.
Stiffness: The ability of ASTM A570 Grade 30 ASTM A570/A570M to resist elastic deformation under stress.
Strength: The ability of ASTM A570 Grade 30 ASTM A570/A570M to resist deformation and fracture under external forces.
Hardness: The ability of ASTM A570 Grade 30 ASTM A570/A570M to resist the pressure of a harder object into it.
Impact toughness: The ability of ASTM A570 Grade 30 ASTM A570/A570M to resist fracture under impact loading.
Fatigue strength: The maximum stress that does not cause fracture when ASTM A570 Grade 30 ASTM A570/A570M is subjected to numerous repeated or alternating loads.
Fracture toughness: a performance index used to reflect ASTM A570 Grade 30 ASTM A570/A570M is ability to resist crack instability and expansion
