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.

How to Save with Investment Casting.
How to find a reputable investment caster – Finding a reputable investment caster isn’t always easy. Look for people who have been in business a long time. Look for things like the ISO seals, because when investment casters are adhering to the ISO 9000 system they have committed to a quality program. A quality program generally means you have a reputable caster. Shelmet Investment Casting Company, Inc, has been in business for over 55 years and we are ISO 9008 certified which is part of the ISO9000 system. Shelmet Precision Casting, Inc is currently evaluating and expecting approval on the ISO2015 update. We believe that we are one of the best investment casters in the industry. Why do we believe that? Because we live it every day.
Professional precision casting investment foundries like Shelmet Precision Casting, Inc, create a variety of metal castings in sizes from fractions of an ounce to 20 pounds or more. Different types of investment casting and precision casting have dated back a few thousands of years. Almost the same methods of melting metals, creating simple dies for multiple instances, and creating the finished metal casting used very similar techniques long ago. Highly detailed castings make investment castings the best choice for producing finished metal castings often produced from various alloys. Artworks of copper and bronze and even gold were created using precision casting techniques, because these metals and simple metal alloys were more easily obtainable.
Wax Room: pattern waxes, soluble waxes, specialty waxes, wax reclamation and recycling products, wax pattern cleaner and pattern wetting solution
Refractories: fused silica, tabular alumina, fused brown alumina, alumina silicates, molochite, white alumina, sand & flours, zirconia, plaster, fiber enhanced refractories and carbon stucco
Binders: binders, silica, gravity chart, wetting agents and other additives
Crucibles: crucibles and pour cups
Metals: scrap and copper, brass, steel, nickel, cobalt and other alloys
Of course each casting company will have their own particular combinations of casting equipment, depending on the types of metals and alloys they specialize in and on whether their focus is investment casting, die casting, sand casting or other casting operations.

Investment casting parts and structures have high strength and mechanical properties, and are seldom susceptible to worn out fatigue. The mechanical properties and micro-structure of the alloys can be easily controlled by the setting time, as rapid cooling techniques produce excellent strength casting parts.
