The maximum pressure for hot isostatic pressing (HIP) can range from 15,000 psi to 44,000 psi (100 MPa to 300 MPa) based on the information provided in the references. HIP combines high temperatures, reaching up to 2,000°C, with isostatically applied gas pressures. The pressure is applied using an inert gas such as argon. The aim of HIP is to achieve near-net shape and full density of the material being processed. The process involves hermetically sealing powder in a container that is flexible at elevated temperatures, heating it within a pressurized vessel, and holding it for a specified time. The pressure medium, usually an inert gas, is pressurized at pressures ranging from 100 to 300 MPa (15 to 45 ksi). The temperature for HIP is material dependent, with typical production equipment able to heat parts from 1,000 to 1,200 °C (2,000 to 2,200 °F). HIP allows for better uniformity of compaction and can be used to compact more complex forms. It is important to note that HIP applies isostatic pressure using gas pressure, while hot pressing applies only uniaxial pressure.
