induction hardening and tempering of tools

WHAT ARE THE STEELS?Tool and die steels are covered in BS 4659:1989, although both American nomenclature and a variety oftrade names are also in use. Available in high-quality grades, these specifically-designed steels can be groupedbroadly according to t…

effect of surface hardening by induction heating

Surface hardening of carbon steel by high frequency induction heating (HFIH) produces a considerable increase in its resistance to stress corrosion [1, 2]. The magnitude of this increase depends on the depth of surface hardening, on the strength of the spe…

induction surface hardening

Kelvin Effect, Mean Curvatures and Load Impedance in Surface Induction Hardening: An Analytical Approach including Magnetic Losses Abstract– Kelvin effect(Skin effect) is used in surface hardening produced by induction heating of gears, cam forms, camsh…

induction hardening gears

In recent years, gear manufacturers have gained additional knowledge about how technology can be used to produce quality parts. The application of this knowledge has resulted in gears that are quieter, lighter, and lower cost, and have an increased load-ca…

hardening induction coil

Whenever someone is talking about induction heating, reference is often made to the phenomenon of skin effect.1 Skin effect is considered a fun- damental property of induction heating, representing a nonuniform distribution of an alternating current within…

surface hardening of steels

Selective hardening is applied because of one or more of the following reasons:(1) Parts to be heat-treated are so large that conventional furnace heating and quenching becomeimpractical and uneconomical - examples are large gears, large rolls and dies;(2)…

induction surface hardening of steel

High-level surface heating of a thermo technically massive body, when the cooling of the surface to be hardened happens due to abstraction of heat into the body so that the hardening medium is not required, is of both practical and theoretical interest. Ti…
