IHTS Case Studies
For two decades, IHTS has optimized heat treating and quenching techniques for a multitude of parts and materials, from tool steel punches and ductile iron to case hardened steel and field repairability.
Lean, Integrated Heat Treating for S-5 Tool Steel Punches
The expected failure mode for an S-5 tool steel cold working punch is chipping of the cutting edge after making a certain number of holes. After oil quenching the punch is 60-61 HRC and does not have much ductility. However, after an intensive water quenching the same design punch made of the same S-5 alloy steel tempered to the same

Reduce or eliminate long-batch carburizing cycles. The higher the residual compressive surface stresses, the longer the part cyclic fatigue life that can be expected. This is because the surface compression holds the part like a die and this compressive force must be overcome before the part will begin to bend and then fatigue.

“Field repairability” can have an impact in part design and heat treating. The optimal hardened part form, fit and function may have other indirect requirements that should be considered by the lean manufacturing team, such as using an alloy of steel that has “field reparability” and still provides the needed mechanical properties. For example,

For many years, ductile iron castings have been given improved mechanical properties with austemper heat treat quenching processes in hot salt. Austempered Ductile Iron (ADI) was pioneered by Applied Process in close collaboration with the ductile iron foundries. Due to their superior mechanical properties, high ductility, low

Lean integrated heat treating solutions cannot be fully implemented without the development of the proper heat treating equipment. With Direct from the Forge Intensive Quenching (DFIQ) equipment on the forging shop floor, the forger is also the part heat treater; the forger becomes a “captive heat treater” adding more value to the forger’s link
