45# steel is high-quality carbon structural steel. The hardness HRC is 48-55. 45# steel plates are widely used in aerospace, power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries. Used to make small cross-section quenched and tempered parts with larger load and large normalized parts with less stress.
