AISI 1030 is a high-carbon steel containing approximately 0.30% carbon that can be hardened by heat treatment to a maximum hardness of approximately Rockwell C 50. Soft annealed high carbon steel is intended for applications requiring moderate forming, while soft spheroidized annealed product is intended for applications requiring maximum cold forming. The soft spheroidized annealed product is processed to give the lowest hardness for maximum formability.
Applications of AISI 1030 Steel
This grade of steel is used for machinery parts, brackets, brakes, clips, clutches, springs, washers and for a wide range of applications that can make use of its good combination of mechanical properties.

The machinability rating of AISI 1030 carbon steel is 70.
The formability of AISI 1030 carbon steel in the annealed condition is good.
AISI 1030 carbon steel can be welded by all welding methods. It is advisable to pre-heat the heavy sections of this steel at 149 to 260°C (300 to 500°F) and then post-heat at 593 to 649°C (1100 to 1200°F) for welding.
AISI 1030 carbon steel is heat treated at 816 to 871°C (1500 to 1600°F) and quenched in water. This process is followed by a tempering treatment.
AISI 1030 carbon steel is forged at 982 to 1260°C (1800 to 2300°F).
Hot working of AISI 1030 carbon steel is performed at 93 to 482°C (200 to 900°F).
In the annealed condition, cold working of AISI 1030 steel may be performed by conventional methods. After annealing, a full or stress relief anneal may be required.
Annealing of AISI 1030 carbon steel is carried out at 871 to 982°C (1600 to 1800°F) and then slow cooled in the furnace. Stress relief annealing may be carried out at 538°C (1000°F).
AISI 1030 carbon steel is hardened by heat treatment or cold working.
