GB 9Cr3Mo GB/T 13314 Mechanical
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 GB 9Cr3Mo GB/T 13314 to produce permanent deformation without causing damage under external forces.
Stiffness: The ability of GB 9Cr3Mo GB/T 13314 to resist elastic deformation under stress.
Strength: The ability of GB 9Cr3Mo GB/T 13314 to resist deformation and fracture under external forces.
Hardness: The ability of GB 9Cr3Mo GB/T 13314 to resist the pressure of a harder object into it.
Impact toughness: The ability of GB 9Cr3Mo GB/T 13314 to resist fracture under impact loading.
Fatigue strength: The maximum stress that does not cause fracture when GB 9Cr3Mo GB/T 13314 is subjected to numerous repeated or alternating loads.
Fracture toughness: a performance index used to reflect GB 9Cr3Mo GB/T 13314 is ability to resist crack instability and expansion
