to be used in the manufacture of anti-friction bearings. And is the most common steel grade in ASTM A295 standard for high-carbon anti-friction bearing steel.
What is 52100 bearing steel?
52100 bearing steel is a high carbon, chromium containing low alloy
steel that is through hardening and noted in particular for use as
52100 bearing steel is one kind of special steel with features of
high wear resistance and rolling fatigue strength. High-carbon chromium
bearing steel, engineering steel and some types of stainless steel and
heat resistant steel are used as materials of bearings and for other
Advantages of Chrome Bearing Steel 52100:
Superior hardness, 60-67 on Rockwell hardness scale (Rc) at room temperature
High carbon chrome alloy steel
Operates continually at temperatures up to 120°C
Used to produce precision ball bearings and roller bearings

4. Forging of A295 52100 Bearing Steel
52100 alloy steel is forged at 927 to 1205°C, and should not be forged
below 925ºC. A post-forge equalization treatment is recommended at 745ºC
for 4-6 hours followed by air cooling for SAE/AISI 52100 steel.
6. Heat Treatment for ASTM 52100 Bearing Steel
52100 alloy bearing steel is heated at 816°C followed by quenching in
oil. Before performing this process, it is subjected to normalizing heat
treatment at 872°C followed by slowly cooling in order to reduce the
AISI 52100 bearing steels alloy can be hot worked at 205 to 538°C.
AISI 52100 bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.
For spheroidize anneale, the following isothermal anneal is recommended:
1500ºF (815ºC) for 3 hours
1350ºF (735ºC) for 4 hours
1250ºF (675ºC) for 3 hours
Slow cool to 1000ºF (540ºC) then air cool.
AISI 52100 alloy bearing steel could be hardened by quenching in water from 801-829 degree or quench in oil from 816-842 degree.
Temper to desired hardness as indicated by tempering curves after water or oil quench.
5. Applications of 52100 Bearing Steel
steel 52100 grade bearing steel is mainly used for the manufacture of
aircraft bearings and other highly stressed parts. This steel grade
52100 steel is preferably vacuum arc re-melted to give optimum
Typical applications: Bearing Manufacture, CV joints, ball screws, gauges, knife etc.

Forged flanges have the better mechanical properties than any other kinds of flanges. They use pipe billets as raw materials. They are constantly hammered after cutting to eliminate defects of steel ingots like segregation and incompact structure. They use carbon steel, alloy steel and stainless steel as main materials. The main anticorrosion methods include oil coating and galvanization. Due to good pressure-resistant and temperature-resistant properties, they are suitable for high-pressure and high-temperature working environment.
