Excellent Performance En 100cr6 Material Preferred Steel For Bearing Manufacturing - China

At the heart of modern industry, a material is quietly changing the rules of the mechanical transmission game.

From high-speed automotive wheel hub bearings to massively loaded wind turbine bearings, from precision aircraft engines to industrial robot joints—EN 100Cr6 material, with its unparalleled performance, has become the "king of the choice" in bearing manufacturing.

But what exactly makes this material so special? Why is it so favored by the world's top bearing manufacturers? Core Performance Advantages: Why Choose EN 100Cr6 material? 1 - Superior Rolling Contact Fatigue Strength

The most outstanding characteristic of EN 100Cr6 is its excellent rolling contact fatigue resistance.

With proper heat treatment, the material can withstand billions of rolling cycles without fatigue failure.

This is due to:

- Fine carbide distribution: Uniformly dispersed carbides provide excellent wear resistance

- High purity: Strictly controlled inclusion content ensures fatigue life

- Optimized microstructure: A perfect ratio of tempered martensite and retained austenite 2 - Excellent hardenability and heat treatment stability

- Full-section through-hardening: Uniform hardness is achieved even in large cross-sections

- Minimal heat treatment distortion: Excellent dimensional stability reduces machining allowances

- Good tempering stability: Maintains stable performance at operating temperatures 3 - Excellent machinability

- Excellent spheroidizing annealing condition: Easily machined and formed

- Excellent machinability: Moderate hardness in the annealed state makes it easy to machine

- Good hot workability: Suitable for various forming processes Heat treatment process: The key to unlocking the material's potential Standard heat treatment process route

1 - Spheroidizing annealing (pretreatment)

- Temperature: 740-760°C

- Holding time: Determined by cross-section thickness

- Cooling Method: Furnace cooling to below 600°C, then air cooling

- Purpose: Obtain spheroidal carbide structure and improve cutting performance 2 - Quenching and Hardening

- Austenitizing Temperature: 840-860°C

- Holding Time: Allow for thorough heating, generally 30-60 minutes

- Cooling Medium: Oil quenching or step quenching

- Goal: Obtain martensitic structure, hardness ≥ 62 HRC Application of Advanced Heat Treatment Technologies

In modern bearing manufacturing, EN 100Cr6 material can also utilize more advanced heat treatment processes:

- Vacuum quenching: Avoids oxidation and decarburization, improving surface quality

- Low-temperature tempering: Achieves higher hardness and wear resistance

- Cryogenic treatment: Reduces retained austenite and improves dimensional stability Songshun Company Website:
