E52100 and GCr15 are bearing steels, one of which is ASTM and the other GB.
In fact, the two basic equivalent, in a certain range of permissible requirements can be equivalent to substitute for use.
GCr15 bearing steel is a kind of high carbon chromium bearing steel with less alloy content, good performance and the most widely used.
After quenching and tempering, it has higher hardness, uniform structure, good wear resistance and high contact fatigue performance. The steel has moderate cold working plasticity, general cutting performance, poor welding performance, great sensitivity to the formation of white spots, and temper brittleness.
E52100 bearing steel is a kind of precision special bearing steel after electroslag remelting.
It has the characteristics of high purity, high density, good carbide uniformity and better fatigue performance than ordinary bearing steel.E52100 bearing steel is suitable for manufacturing military bearing products, special bearings, aeroengine bearings, precision instruments, precision spindle bearings, etc.
The comparison of toughening chemical composition of GCr15 bearing steel and E52100 bearing is as follows:
|
Grade |
C |
SI |

E52100 |
0.95～1.05 |
0.15～0.35 |
0.15～0.35 |
≤0.027 |
≤0.020 |
1.30～1.60 |
≤0.30 |
|
≤0.25 |
It is obvious that you could check both material with similar with 90% no matter chemical component and application .
It just with difference standard and of course, the price with difference .
GCr15 steel normally will favorable than E52100 in price in China marketing because GCr15 with great marketing in machine marketing , meanwhile , GCr15 steel ‘s production process with not complicated comparing with the steel of E52100 .
E52100 steel it need to do with ESR process , it will increase the production cost and time , it is no double that .
Of course , E52100 steel with high class in quality in the bearing steel with most industrial .
The buyers will choose the properties and depend on the cost to make the selection .
