SAE 1045 Calibrated(cold drawn) Carbon Steel Round Bar 1045
Quick Details
1: SAE 1045 steel introduction
C45 is a kind of medium carbon high quality steel with high strength. Due to poor hardenability, it is generally used in normalizing state. When the mechanical property is required to be high, quenching and tempering treatment is adopted. Cold deformation plasticity is medium, annealing and normalizing machinability is better than quenching and tempering.

The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: Heat Treatment
SAE 1045 carbon steel can be hardened by heating between 815- 871°C (1500 - 1600°F), which should be followed by water quenching. Then it should be tempered.
Forging
SAE 1045 carbon steel should be forged at 1260°C (2300°F) down to 982°C (1800°F).
Hot Working
SAE 1045 carbon steel can be hot worked in the range of 482 to 649°C (900 to 1200°F).
Cold Working
Cold working SAE 1045 carbon steel is possible using all the conventional methods. In case of prolonged cold working, it is recommended that stress relief annealing be carried out.
Annealing
Complete annealing of this alloy can be achieved between 871-982°C (1600 to 1800°F) followed by slow furnace cooling. This will provide the alloy with a tensile strength of about 65 ksi. A stress relief annealing can be performed if required at 538°C (1000°F).
Tempering
Tempering should be followed by heat treatment and quenching at 315 to 538°C (600 to 1000°F) based on the strength level required. For example 538°C (1000°F) temper provides the alloy with a tensile strength of 90 ksi.
Hardening
SAE 1045 carbon steel can be hardened by cold working and by heat treatment, quenching and tempering.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface
