Exploring the Properties and Uses of 100Cr6 Steel Grade

[ad_1] 100Cr6 steel grade is a high carbon chromium bearing steel that is commonly used in the production of rolling bearing components such as balls and rollers. It is known for its excellent hardenability, high wear resistance, and good toughness.

Mechanical properties of 100Cr6 steel grade include:

1. Hardness: The steel has a high hardness level, typically ranging from 60 to 66 HRC (Rockwell hardness scale). This enables it to withstand heavy loads and resist deformation.

2. Yield strength: The yield strength of 100Cr6 steel grade is about 750 MPa, indicating its ability to resist permanent deformation under load.

3. Tensile strength: The tensile strength of this steel grade is typically between 1030 and 1230 MPa. This high tensile strength provides it with good structural integrity.

4. Elongation: The elongation at break of 100Cr6 steel grade is usually around 16%, indicating its ability to withstand stretching and bending forces without fracturing.

5. Impact toughness: This steel grade exhibits good impact toughness, which means it can absorb energy without fracturing or breaking easily.

Chemical composition of 100Cr6 steel grade:

The chemical composition of 100Cr6 steel includes:

1. Carbon (C): The carbon content in 100Cr6 steel grade is typically between 0.95% and 1.05%. Carbon contributes to the steel’s hardenability and strength.

2. Chromium (Cr): The chromium content in this steel grade is about 1.30% to 1.65%. Chromium adds to the steel’s wear resistance, hardness, and corrosion resistance.

3. Silicon (Si): The silicon content is typically around 0.15% to 0.35%. Silicon helps improve the steel’s strength and resistance to oxidation.

4. Manganese (Mn): The manganese content ranges from 0.15% to 0.45%. Manganese contributes to the steel’s hardenability and improves its toughness.

5. Sulphur (S) and phosphorus (P): These elements are present in small amounts, usually limited to 0.025%. They are considered impurities and are kept low to ensure better steel performance.

Uses of 100Cr6 steel grade:

The excellent mechanical and chemical properties of 100Cr6 steel grade make it suitable for various applications, including:
