Case Hardening Steel
Case hardening steel is a type of steel with a low carbon content, but with a high carbon concentration on its surface, designed to increase surface hardness. This steel undergoes a heat treatment process called carburizing, where carbon is diffused onto the surface, hardening it while maintaining a softer and more ductile interior. The chemical composition typically consists of low-carbon content (around 0.1% - 0.25% carbon), and during the carburizing process, carbon is introduced onto the surface of the steel.These properties make case hardening steel ideal for use in parts such as gears, bearings, and automotive components, where wear resistance and high strength are essential. Surface smoothness is produced within h9, h11 tolerances. Our standard lengths are 3 meters, and special diameters and dimensions can be made according to customer demand.
(Upon customer request, protective, specially packaged (burlap, crate, etc.) packaging can be provided.)
The chemical analysis of case hardening steel generally contains the following elements:
- Carbon (C): Present in low levels, which is increased during the carburizing process to enhance surface hardness.
- Manganese (Mn): Improves the strength of the steel and provides stability during heat treatment.
- Silicon (Si): Increases the resistance of the steel to oxidation.
- Sulfur (S) and Phosphorus (P): These elements are kept to a minimum, as higher levels can negatively affect the machinability and strength of the steel.
- Chromium (Cr) and Nickel (Ni): Sometimes added, especially in high-strength applications, to improve the steel’s resistance to corrosion.
