Hot Isostatic Pressing Eliminates Casting Defects and Scrap Loss for as Little as 0.10 USD/lb.
by Dr. Johan Hjarne
Rapid cooling has drastically reduced HIP operating costs, and interest in insourcing the technology grows every year. For a large-production HIP unit used for castings of steels, ductile cast iron, titanium, or aluminum, the HIP cost is approximately 0.10-0.15 USD/lb, depending on material. This cost should be compared with the expense and time spent on NDT, weld repairs, and high scrap rates, which to a large extent can be excluded when HIP is applied.
