Product Description

AISI L3 100cr6 DIN1.3505 52100 Bearing SteelAISI L3 100cr6 DIN1.3505 52100 Bearing SteelAISI L3 100cr6 DIN1.3505 52100 Bearing SteelIntroduction:

52100 bearing steel is a high carbon, chromium containing low alloy steel that is through hardening and noted in particular for use as bearings.

Applications:

52100 bearing steel is primarily used for the manufacture of aircraft bearings and other highly stressed parts. It has the good rolling fatigue strength required at operating temperatures less than 400°F (200°C). The grade is preferably vacuum arc re-melted to give optimum performance.

Quality Standard:

JIS G4805 1999 high carbon chromium bearing steels
DIN 17230-1980 Ball and Roller Bearing Steels
ASTM A29 Standard Specification Steel Bars, Carbon and Alloy, Hot-Wrought, General Requirements

HEAT TREATMENT:

· FORGING:52100 bearing steel is forged at 1950 - 2100°F (1065 - 1150°C), and should not be forged below 1700°F (925°C.) A post-forge equalization treatment is recommended at 1375°F (745°C) for 4-6 hours followed by air cooling.
· ANNEALING: 52100 bearing steel is annealed at 872°C (1600°F) followed by slowly cooling to reduce cold working or machining stress.
· HARDENING: 52100 bearing 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.

Mill′s test certificate:
