WebNitriding is a case hardening process that depends on the absorption of nitrogen into the steel. All machining, stress relieving, as well as hardening and tempering are normally … WebCase hardening is the process of hardening the surface of a metal by infusing elements into the material’s surface, forming a thin layer of harder alloy. Combined with a subsequent hardening operation the desired component properties can be varied to suit the application. Neutral hardening

Case-hardening involves packing the low-carbon iron within a substance high in carbon, then heating this pack to encourage carbon migration into the surface of the iron. This forms a thin surface layer of higher carbon steel, with the carbon content gradually decreasing deeper from the surface. See more Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal at the surface. For iron or … See more Carbon itself is solid at case-hardening temperatures and so is immobile. Transport to the surface of the steel was as gaseous See more Flame or induction hardening Flame or induction hardening are processes in which the surface of the steel is heated very rapidly to high temperatures (by direct application of an oxy-gas flame, or by induction heating) then cooled rapidly, generally … See more • Differential hardening • Diffusion hardening • Quench polish quench • Shot peening • Surface engineering See more Early iron smelting made use of bloomeries which produced two layers of metal: one with a very low carbon content which is worked into See more Both carbon and alloy steels are suitable for case-hardening; typically mild steels are used, with low carbon content, usually less than 0.3% (see See more Parts that are subject to high pressures and sharp impacts are still commonly case-hardened. Examples include firing pins and rifle bolt faces, or engine camshafts.
