45# hot rolled steel sheet

No. 45 steel is widely used in machinery, when it is not heat treated: HB≤229; heat treatment: normalizing; impact energy: Aku≥39J; high strength, good plasticity and toughness, 45# steel plate after quenching without tempering, the hardness is greater than HRC55 (Up to HRC62) is qualified. After heat treatment and tempering, it can reach HRC42-46, which can not only ensure its good mechanical properties, but also obtain the hardness requirements of the surface.
