St52 Auto Part Steel Pipe The material of this kind of steel is medium carbon structural steel, which has good cold and hot working properties, good mechanical propertie, wide source and low price , so they are widely used. Its biggest weakness is low hardenability, and workpieces with large cross-sectional dimensions and relatively high requirements should not be used. Widely used in machinery, without heat treatment: HB≤229; heat treatment: normalizing; impact energy: Aku≥39J; high strength, good plasticity and toughness, 45# steel plate after quenching and before tempering, the hardness is greater than HRC55 (the highest possible Up to HRC62) is qualified, after heat treatment, and then tempering can reach HRC42-46, which can not only ensure its good mechanical properties, but also obtain the hardness requirements of the surface, used to make small cross-section quenched and tempered parts and Large normalized parts with less stress, and surface quenched parts that do not require high core strength, such as pins, guide posts, watch hands and other components.
