The specification of 100Cr6 steel calls for a material that is a high carbon, chromium alloy steel. It is primarily used in applications where high levels of hardness, wear resistance, and fatigue strength are required. This steel grade is commonly utilized in the automotive industry, specifically for manufacturing bearings, shafts, and other components that are subjected to high loads and friction.

The mechanical properties of 100Cr6 steel include a high hardness level, typically ranging from 61-65 HRC (Rockwell hardness), which provides excellent wear resistance. It has a high ultimate tensile strength, typically around 900-1000 MPa, ensuring the material can withstand heavy loads and potential impact. Fatigue strength is also a notable property, as 100Cr6 steel offers excellent resistance to cyclic loading and continuous stress.

The chemical composition of 100Cr6 steel is crucial for its properties. It is a chromium alloy steel, with carbon being the main alloying element. The typical chemical composition (in weight %) is as follows:
– Carbon (C): 0.95-1.05%
– Chromium (Cr): 1.30-1.65%
– Manganese (Mn): 0.25-0.45%
– Silicon (Si): 0.15-0.35%
– Phosphorus (P): max 0.025%
– Sulfur (S): max 0.015%

The high carbon content provides hardness and wear resistance, while chromium enhances the material’s toughness and corrosion resistance. Silicon and manganese contribute to the steel’s strength and hardenability. The controlled levels of phosphorus and sulfur ensure good machinability and maintain the material’s overall quality.

By utilizing 100Cr6 steel in the automotive industry, manufacturers can revolutionize their products by improving the durability, performance, and longevity of key components. Its high mechanical properties and well-balanced chemical composition make it an ideal choice for automotive applications, resulting in enhanced safety, reliability, and efficiency.
