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.

Principal Design Features | 52100 is a low alloy, vacuum melted, steel of very high strength. Essentially it is a modified AISI 4340 steel with silicon, vanadium and slightly greater carbon and molybdenum content than 4340. 52100 has a very good combination of strength (280 to 305 ksi), toughness, fatigue strength and good ductility. It is a through hardening alloy. |

Alloy Steel 52100 Applications | AISI 52100 alloy steel is used in high strength bolts, airframe parts, and aircraft landing gear. |
Alloy Steel 52100 Machinability | Machining is best accomplished with the alloy in the normalized or normalized and tempered condition. Final machining to finish tolerances is done by grinding with care due the hardness of the heat treated alloy (Rockwell C 55). It is important to do a stress relief anneal at 550 F after finish grinding. |
Alloy Steel 52100 Forming | Formability by conventional methods is good in the annealed condition. The alloy behaves much like AISI 4340 steel. |
Alloy Steel 52100 Welding | 52100 can be welded by fusion methods or by flash resistance welding. Approved procedures must be used for fusion welding, including pre and post-heating practice, because the alloy will air harden due to heat input from welding. Following welding it is essential to re-normalize or re-normalize and temper prior to the final hardening heat treatment. |
Alloy Steel 52100 Heat Treatment | 52100 must be normalized at 1700 F before hardening. After the normalizing treatment the alloy is hardened by heating to 1600 F and oil quenching. Tempering is then done last. |
Alloy Steel 52100 Forging | No data. The alloy is forgeable - contact the supplier for details. |
Alloy Steel 52100 Hot Working | No data. Heat input can cause this alloy to air harden. Contact the alloy supplier for information as to the advisability of hot working. |
Alloy Steel 52100 Cold Working | In the annealed or normalized condition the alloy has good ductility and can be readily cold worked by conventional methods. |
Alloy Steel 52100 Annealing | Anneal at 1550 F and slow furnace cool at a rate of less than 50 F per hour down to 600 F. From there it may be air cooled. |
Alloy Steel 52100 Aging | Not applicable to this alloy. |
Alloy Steel 52100 Tempering | Temper at 600 F to give a nominal 300 ksi strength. |
Alloy Steel 52100 Hardening | 52100 hardens from cold working and by heat treatment. See "Heat Treatment" and "Tempering". |
