- Commodity name: Q355GNH Steel
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.
