Frequently Asked Questions
What is Hot Isostatic Pressing (HIP)?
Hot Isostatic Pressing is a process in which components are subjected to the simultaneous application of heat and pressure. The internal voids of the components being processed, bond together making them stronger. In most cases, this does not change the shape of the parts.
Why use HIP?
The HIP process produces a component with higher quality with improved mechanical properties. Scrap can be dramatically reduced, and machining may be minimized. The rejuvenation of old parts is also a possibility with HIP. Additionally, it can be used on a wide variety of materials, in a number of applications.
What are possible HIP Applications?
- Casting Densification
- HIP Brazing
- Powder Metals including MIM
- Additive Manufacturing (3D Printing)
- Cladding and Diffusion Bonding
- Repairs and Rejuvenation
What are the benefits of HIPing?
- Improve mechanical properties
- Improve fatigue life
- Remove internal porosity
- Improve the x-ray standard
- Reduce property scatter
- Reduce rejection rate
- Reduce scrap losses
- Reduce weld repair
- Rejuvenate old parts
What materials can be HIPed?
- Powder Metals
- Stainless Steel
How is pricing established?
Pricing is based on size, the material and which cycle your parts need to process. Combining or “piggybacking” your part with other customers that use the same process cycle can create significant cost savings.
What is the turn time?
Howmet HIP offers the fastest turnaround time in the HIPing industry averaging 3 to 6 days.
