    Three large bearing sets being removed from Metlab180" diameter by 156" high carburizing furnace from the hardening temperature (1550°F) for subsequent quenching into agitated, hot oil. Parts were carburized to a case depth in excess of 0.200" ECD. Fixture and component weight is about 40,000 pounds. Metal

  • Induction hardening - Wikipedia

    Induction hardening is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without

  • Heat treatment - Wikipedia

    Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, normalizing and quenching. It is noteworthy that while the

    the microstructure and mechanical properties of the material. This investigation compares an inductive with a conventional furnace heat treating process of a 50CrMo4 steel, however only the austenitizing treatment was changed and subsequent quenching and tempering was done in the same way. To this end experiments

    Harden surface only, Localized induction hardening, Control heat so that only the surface is made austenitic and quench. Harden surface only Carburizing: adding carbon to the surface of steel, in a controlled atmosphere furnace, to increase the ultimate hardness, typically to a depth of 0.5 to 1.0 mm (0.020 to 0.040 in.).

  • Induction hardening versus case hardening - SMS Elotherm GmbH

    This article compares the traditional process of case hardening with induction hardening and proves that the induc- tion technology mainly is .. Example 1: Case hardening of a case-hardened steel (16MnCr5). Case hardening depth of approx. 2 mm and a hardness of. 57-62 HRC in a shaft furnace: Workpiece: Shaft

  • Induction quench hardening of carbon steel axe blades - Theseus

    Induction quench hardening of carbon steel axe blades. Supervisor (Arcada): .. This is means that the hardening machine needs minor adjustments and ingoing investigation within the theory of harden ability and tempering of the steel. The objective of this The cycle which is used is 440°C in furnace for 5 hours. When.

  • Introduction to Surface Hardening of Steels - ASM International

    mary surface-hardened steels used in wear applications with fatigue loads include heavy case-hardened steels and flame- or induction- hardened steels. .. Although the furnace enclosure in some respects becomes more com- plex, the atmosphere is greatly simplified. A sin- gle-component atmosphere consisting solely of

  • Volume 4C Induction Heating and Heat Treatment - ASM International

    The surface hardness, case depth, and core requirements will typically determine the grade of steel to be used. The attainable hardness increases along with the furnace hardening. This phenomenon is some- times referred to as superhardening (Ref 12). The microstructure present in a part prior to induction hardening

  • Induction hardening as an alternative to case hardening | eldec

    If one compares the two methods for hardening steel workpieces (for a general explanation of hardening see here: Hardening), then the first striking difference is the parts handling. While case hardening processes a large number of workpieces at the same time, induction hardening focuses on the individual workpiece.
