Alloy is a steel that contains one or more alloying elements, which produces specific properties not found in regular carbon steel. Alloy steels are generally more responsive to mechanical and heat treatments.

|4130||General purpose alloy. Offers good strength and toughness for moderately stressed parts.|
|4140||Medium carbon steel that is widely used for general purposes. Good hardenability, strength, toughness, wear resistance, and ductility.|
|4150||Similar to 4140, but increased carbon content leads to higher hardenability. Offers excellent machinability and tool life.|
|4340||Highly alloyed steel. Used in heavy-duty conditions and for heavily stressed parts.|
|8620||General purpose alloy. It is the most widely used of all case hardening alloys.|
|52100||A high carbon, chromium containing, low alloy steel. A moderately deep hardening alloy with high resistance to wear, medium toughness and low resistance to softening at high temperatures.|
|41L40||Can be quenched and tempered for a broad range of strength levels.|
|86L20||Case hardening steel that is supported by a tough, ductile core. Minimal distortion in heat treatment.|
