Driving Efficiency and Durability with 100Cr6 Steel in Bearing Production

The specification for driving efficiency and durability with 100Cr6 steel in bearing production involves considering the mechanical properties and chemical composition of the steel.

1. Mechanical Properties: 100Cr6 steel, also known as AISI 52100 or EN31 steel, is a high carbon, chromium alloy steel primarily used for producing bearings. The mechanical properties that contribute to driving efficiency and durability include:

– Hardness: The steel should have a high hardness level to withstand the load and wear conditions in bearing applications. Typically, the hardness of 100Cr6 steel falls within the range of 60-66 HRC (Rockwell hardness).
– Strength: The steel should possess sufficient strength to withstand the stresses and loads experienced during bearing operation. The tensile strength of 100Cr6 steel is typically around 700-900 MPa.
– Fatigue Resistance: The steel should exhibit good fatigue resistance to withstand repeated stress cycles without failure. 100Cr6 steel is known for its excellent fatigue resistance, making it suitable for high-speed and heavy-load bearing applications.
– Wear Resistance: The steel should have high wear resistance to withstand the frictional forces experienced in bearing operation. The combination of high carbon content and chromium in 100Cr6 steel provides good wear resistance.

2. Chemical Composition: The chemical composition of 100Cr6 steel affects its mechanical properties. The typical chemical composition of 100Cr6 steel is as follows:

– Carbon (C): 0.95-1.10%
– Chromium (Cr): 1.30-1.60%
– Manganese (Mn): 0.25-0.45%
– Silicon (Si): 0.15-0.35%
– Phosphorus (P): Maximum 0.025%
– Sulfur (S): Maximum 0.025%

The high carbon content in 100Cr6 steel contributes to its hardness and wear resistance, while the chromium content enhances its hardenability and corrosion resistance.

In summary, driving efficiency and durability in bearing production with 100Cr6 steel involve specifying the desired mechanical properties (hardness, strength, fatigue resistance, and wear resistance) and ensuring the appropriate chemical composition (carbon, chromium, manganese, silicon, phosphorus, and sulfur). This combination of properties and composition makes 100Cr6 steel a suitable choice for applications requiring reliable and long-lasting bearings.
