Material: 100Cr6 Steel

Specifications and Properties:

1. Mechanical Properties:
– Tensile Strength: The tensile strength of 100Cr6 steel is typically in the range of 780-980 MPa. This high tensile strength makes it suitable for applications where high strength and durability are required.
– Yield Strength: The yield strength of 100Cr6 steel is usually around 550-700 MPa. This indicates the maximum stress that the material can withstand before undergoing plastic deformation.
– Hardness: 100Cr6 steel has a typical hardness of 60-66 HRC. This high hardness provides excellent wear resistance, making it suitable for applications in bearings, rolling elements, and other high-load applications.
– Impact Strength: 100Cr6 steel has good impact strength, ensuring that it can withstand sudden shock loads without failure.

2. Chemical Composition:
– Carbon (C): The carbon content in 100Cr6 steel is typically between 0.95% and 1.05%. Carbon provides strength and hardness to the material.
– Chromium (Cr): Chromium is the most significant alloying element in 100Cr6 steel, with a typical content of 1.35% to 1.65%. It enhances hardness, wear resistance, and corrosion resistance.
– Manganese (Mn): 100Cr6 steel contains manganese in a range of 0.25% to 0.45%. Manganese improves hardenability, strength, and machinability.
– Silicon (Si): The silicon content in 100Cr6 steel is around 0.15% to 0.35%. Silicon aids in deoxidation and enhances response to heat treatment.
– Phosphorus (P) and Sulfur (S): Phosphorus and sulfur are present in limited amounts, generally below 0.025%. These elements may improve machinability but can have detrimental effects on some mechanical properties if present in high amounts.
– Other elements: 100Cr6 steel may contain small amounts of other elements like nickel (Ni) and molybdenum (Mo). These elements may be present as impurities or deliberate additions to enhance specific properties.

The exceptional corrosion resistance of 100Cr6 steel is attributed to its high chromium content, which forms a protective oxide layer on the surface. This oxide layer acts as a barrier, preventing further corrosion and improving the material’s resistance to various corrosive environments. The precise mechanism behind this exceptional corrosion resistance is still an area of ongoing research and exploration.
