45 carbon steel bar is a high-quality medium-carbon steel with a carbon content of about 0.45%, offering high strength and good ductility, making it suitable for manufacturing components that require hardness and wear resistance. After quenching and tempering, its hardness, strength, and toughness are enhanced, making it widely used in industrial manufacturing for mechanical parts such as shafts, gears, and bolts.
Following quenching and tempering, the hardness of 45 steel can reach around HRC50, providing good wear resistance and impact toughness, allowing it to remain stable in high-stress environments. Its high tensile strength makes it suitable for parts bearing significant loads, commonly used in high-strength mechanical structures.
45 carbon steel bar also has good machinability, compatible with various machining methods, and possesses a certain degree of weldability, meeting diverse manufacturing needs. It is widely used in automotive and machinery manufacturing.
