Forged 1045 steel advantages:
Good machinability
1045 forged steel is easy to machine by turning, milling, drilling and other machining, and is suitable for manufacturing parts of various complex shapes.
Moderate strength and toughness
Through heat treatment processes such as normalizing, quenching and tempering, 1045 carbon steel forging has achieved a good balance between strength and toughness, which can not only withstand large loads, but also resist impact and vibration to a certain extent.
Wide applicability
1045 steel forgings are suitable for industrial fields that require high wear resistance and strength, such as machinery manufacturing, automobile industry, petrochemical industry, etc.
High cost-effectiveness
1045 forged steel is usually more economical than high-alloy steel and has high cost-effectiveness.
