(Practice)Standard Practice for Hot Isostatic Pressing of Steel, Stainless Steel, and Related Alloy Castings
Standard Practice for Hot Isostatic Pressing of Steel, Stainless Steel, and Related Alloy Castings
ABSTRACT
This practice covers general requirements for Hot Isostatic Pressing (HIP) of steel, stainless steel, and related alloy castings. HIP is a solid state process which applies heat and pressure simultaneously to objects in an autoclave via an inert gas in such a way as to eliminate internal voids and obtain desired properties. Inert gas is a non-oxidizing gas used for pressurizing a HIP vessel. This practice deals with quality requirements, autoclave type/qualification, temperature uniformity, temperature measurement and control, pressure measurement and control, and gas measurement.
SCOPE
1.1 This practice covers general requirements for hot isostatic pressing (HIP) of steel, stainless steel, and related alloy castings.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
