This is accomplished by several processes such as a carburizing or nitriding process by which a component is exposed to a carbonaceous or nitrogenous atmosphere at elevated temperature. It is faster than carburizing or nitriding etc. (This structure is examined in the article The Crystalline Structure of Metals.) The case depth is rarely more than 2.5 mm. Unlike through hardened steel, case hardened low carbon steels and alloy steels become tough, strong and hard without being brittle. Medium carbon steel contains between 0.30-0.59% carbon and balances ductility and . Read more about this topic: Work Hardening, is it not clear that to give to such women as desire it and can devote themselves to literary and scientific pursuits all the advantages enjoyed by men of the same class will lessen essentially the number of thoughtless, idle, vain and frivolous women and thus secure the [sic] society the services of those who now hang as dead weight?Sarah M. Grimke (17921873), Better reproducibility and interchangeability, Directional properties can be imparted into the metal, Heavier and more powerful equipment and stronger tooling are required, Metal surfaces must be clean and scale-free, Intermediate anneals may be required to compensate for loss of ductility that accompanies strain hardening, The imparted directional properties may be detrimental, Undesirable residual stress may be produced. As a result, it creates fewer pores in concrete structures. Flame hardening is a surface hardening technique which uses a single torch with a specially designed head to provide a very rapid means of heating the metal, which is then cooled rapidly, generally using water. Increases Impact-Resistance & Toughness of Steel. Self-quenching phenomenon applies after removing the heat source from the interaction zone. RHC has a lower drying shrinkage rate as most of the water is used up for the hydration process. During through hardening, the component part is heated in such a way that both the surface and the inner core become uniformly harder. DOE Fundamentals Handbook, Volume 2 and 2. A properly chosen case hardening process contributes to energy savings, cost control, reliability, maintainability and serviceability. For this reason, only low carbon steel with a basic carbon content of less than 0.25% by mass are normally considered., such as mild steel. 2.
