AISI 1030 Steel (UNS G10300)
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. 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.
