Hot Isostatic Pressing (HIP)

The hot isostatic pressing process combines high temperature (up to 2200ºC) and isostatic inert gas pressure (from to 100 to 3100 bar) in a high pressure containment vessel. Heat and pressure, applied simultaneously, eliminate internal voids and residual porosity therefore improving fatigue resistance of fabricated parts and resulting in a very fine grained structure.
 

Advantages

• Great flexibility in the design, chemical composition, particle size distributions used and form
• Increases material properties such as resistance to stress, cracking and corrosion and removes air bubbles
• Allows manufacturing with irregular shapes and complex geometries
• Creates uniformity of properties in all directions (isotropic)
• Reduction of costly operations like machining and welding
• Improves process safety by the elimination of critical welds
• Possibility of graded structures (solid/powder) with perfect bonds between the layers
