Alloy steels (AISI 8620, 9310 and 4140) were hardened using induction hardening
, atmosphere carburizing and vacuum carburizing .
The carburized section will have carbon content high enough so that it can be hardened again through flame or induction hardening
. The objective is to produce a hard, wear-resistant case which will be resistant to both bending and contact fatigue whilst still maintaining its toughness and ductility of the low carbon core as studied by Stephen and Edward .
The process involves centering, turning of journals & camlobes, grinding, induction hardening
& bobbing of gears.
Chapters cover areas including thermodynamics of thermal processing, physical and mechanical metallurgy of thermal processing, and methods for the modeling of casting, industrial heat treatment options, induction hardening
processes, laser surface hardening, and case hardening.
"Ellwood Crankshaft is the only company in the industry that has both induction hardening
and vertical gas nitride hardening processes on-site, and the vertical gas nitriding facility is among the largest in the world," Taylor noted.
(2006) Analysis of temperature and stress fields by induction hardening
. In: 21st Int.
It invests heavily in the development of innovative new services in key areas such as vacuum and plasma technology, induction hardening
and controlled atmosphere heat treatments.
The new plant will ensure continued short delivery times by increasing workflow and enabling processes such as induction hardening
, nitriding, and carburizing.
Radyne builds induction hardening
, tempering, brazing, and soldering equipment.
"But because of the advanced induction hardening
mill at our Port Washington plant, we were able to achieve the needed hardness on thicker material and meet life expectancy projections."
Formed in 1966 by chairman Mr Wally Hammond, Hammond Heat Treatment Ltd currently employs an 86-strong workforce and is comprised of five divisions - batch processing, induction hardening
, the fastener division, the surface engineering division, which is primarily a nitrocarburising process, and the recently formed automotive division, which is focused on high volume induction hardened parts.
