Alloy steels contain different varieties of steels that exceed the composition limits of Mn, C, Mo, Si, Ni, Va, and B set for carbon steels. They are designated by AISI four-digit numbers. They respond more quickly to mechanical and heat treatments than carbon steels.
AISI 52100 alloy steel is known as a high carbon, chromium containing low alloy steel. The following datasheet gives an overview of AISI 52100 alloy steel.
The following table shows the chemical composition of AISI 52100 alloy steel.

Fabrication and Heat Treatment
AISI 52100 alloy steel can be machined using conventional techniques. The machinability of this steel can be improved by performing spherodizing annealing process at 649°C (1200°F) before machining.
AISI 52100 alloy steel can be formed using all conventional techniques such as cold forging or stamping and hot or cold upset forming techniques.
AISI 52100 alloy steel is heated at 816°C (1500°F) followed by quenching in oil. Before performing this process, it is subjected to normalizing heat treatment at 872°C (1600°F) followed by slowly cooling in order to reduce the machining stress.
AISI 52100 alloy steel is forged at 927 to 1205°C (1700 to 2200°F).
AISI 52100 alloy steel can be hot worked at 205 to 538°C (400 to 1000°F).
AISI 52100 alloy steel can be cold worked using conventional techniques in the annealed or normalized conditions.
AISI 52100 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.
AISI 52100 alloy steel is hardened by cold working, or heating and quenching. It can be carburized at 913°C (1675°F) followed by quenching. It is again heated at 788°C (1450°F) followed by quenching for the second time.
AISI 52100 alloy steel is used in bearings in rotating machinery.
