Case hardening of steel is used for numerous applications including for the manufacture of carbon steel forgings and carbon steel pinions. Alloy steels are normally case hardened to increase the metal characteristics. The outer layer of case hardening steel becomes hard, while the Surface hardening (case-hardening) - tec-scienceWith case hardening, low-carbon steels are first enriched with carbon in the surface layer (carburisation) and then quenched! Such components are characterised by their high surface hardness combined with a very tough core (since low-carbon content)! Single-quench hardening. Single quench hardening is a special case hardening

Surface hardening metallurgy Britannica

Alternative Title:case hardening Surface hardening , treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering because it can withstand very high stress and fatigue, a property The history of case hardening and its processes Double Case Hardening is used on both carbon and alloy steels although usually mild steels are used. The Case Hardened steel is formed by diffusing carbon, nitrogen or boron into the outer layer of the steel's surface at high temperature. The newly Case Hardened item can then be heat treated to give the surface layer the desired hardness.
