is a specification that covers 52100 high carbon quality bearing steel,
which will be used in the production of rolling bearings. A 52100 bearing steel is the most common steel in ASTM A295 for high carbon anti-friction bearing steel.
What is 52100 Bearing Steel?
AISI / ASTM
52100 bearing steel is a high carbon, chromium containing low alloy
steel that through hardening and noted, in particular, for use as
52100 bearing steel is a kind of special steel with characteristics
high wear resistance and rolling fatigue strength. High carbon chromium
bearing steel, structural steel and some types of stainless steel and
heat resistant steels are used as bearing materials and for other
Advantages of Chrome 52100 Bearing Steel:
Superior hardness, 60-67 Rockwell hardness (Rc) at room temperature
chrome high carbon alloy steel
Works continuously at temperatures up to 120 กใ C
Used for the production of precision ball bearings and roller bearings
4. Forging A295 52100 bearing steel
52100 alloy steel forging at 927 to 1205 กใ C, and must not be forged
below 925ºC. Treatment after forging is recommended at 745ºC in
for 4-6 hours followed by air cooling for SAE / AISI steel 52100.
6. Heat treatment for ASTM 52100 bearing steel
ASTM / AISI
52100 bearing steel alloy is heated at a temperature of 816 กใ C followed by cooling in
oil. Before performing this process, it is subjected to thermal normalization
processing at 872 กใ C, followed by slow cooling in order to reduce
AISI 52100 bearing alloy steels can be hot worked at 205 to 538 กใ C.
AISI 52100 bearing steel can be cold worked using conventional methods under annealed or normalized conditions.
For spheroidize anneale, the following isothermal annealing is recommended:
1500ºF (815ºC) for 3 hours
1350ºF (735ºC) for 4 hours
1250ºF (675ºC) for 3 hours
Slow cooling to 1000ºF (540ºC) followed by air cooling.
AISI 52100 alloy bearing steel can be quenched by water quenching from 801-829 degree or oil quenching from 816-842 degrees.
Tempers to the desired hardness, as shown by the quenching curves after water or oil quenching.
5. Application of steel 52100 bearing
52100 steel grade bearing steel is mainly used for the production
aircraft bearings and other heavily loaded parts. This steel grade
52100 steel, preferably the vacuum arc is remelted to give optimum
