UNS G10300 S30C Carbon steel

Carbon steels are those that have carbon as the main alloying element. They also contain up to 0.4% silicon and 1.2% manganese. In addition, the residual elements such as copper, molybdenum, aluminium, chromium and nickel are present in these steels.

The AISI 1030 steel is a high carbon steel, and has moderate strength and hardness in the as-rolled condition. It can be hardened and strengthened by cold work. It also has fair machinability, ductility and good weldability.

The following sections will discuss in detail about AISI 1030 carbon steel.
