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

Researchers at NC State have developed a new method to create microfluidic channels and microvasculature in polymers by 3D printing liquid metal ‘fugitive inks’. The liquid metal – an alloy of gallium – can be 3D printed onto polymer substrates and encapsulated with more polymer. The metal can be printed due to the formation of a thin surface oxide on its surface, which stabilizes its shape. Once encapsulated in polymer, this oxide layer can be removed using several techniques, causing the metal to retract from the encasing material. This retraction leaves behind empty microchannels, which can then be used for microfluidics and other applications. One example is to pattern microvasculature into materials in a way that mimics the vasculature of the human body. Although other strategies exist to print fugitive inks, the present work is distinguished by its simplicity and rapid, room temperature processing.
The paper, “3D printing of liquid metals as fugitive inks for fabrication of 3D microfluidic channels” is published online in the journal Lab on a Chip. For more information, visit the website of the journal.
