WebSep 4, 2014 · Case hardening is a heat-treatment process that produces a hard and wear-resistant surface layer, while the inside of the part remains ductile. Think of an M&M candy: hard and crunchy on the outside, soft … 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 steel with low carbon content, which has poor to no hardenability of its own, the case-hardening … 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 wrought iron, and one with a high carbon outer layer. Since the high carbon iron is hot … 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 plain-carbon steel for more information). These … 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. In these cases, the surfaces requiring the hardness may be hardened selectively, leaving the bulk of … See more • Case Hardening • Surface Hardening of Steels • Case Hardening Steel and Metal • "MIL-S-6090A, Military Specification: Process for Steels Used In Aircraft Carburizing and Nitriding" See more Carbon itself is solid at case-hardening temperatures and so is immobile. Transport to the surface of the steel was as gaseous carbon monoxide, generated by the breakdown of the carburising compound and the oxygen packed into the sealed box.
