ASTM A1080/A1080M-19

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.
Designation: A1080 − 15 A1080/A1080M − 19
Standard Practice for
Hot Isostatic Pressing of Steel, Stainless Steel, and Related

Alloy Castings
This standard is issued under the fixed designation A1080;A1080/A1080M; the number immediately following the designation indicates
the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*
1.1 This practice covers general requirements for Hot Isostatic Pressinghot 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 as standard. No other units of measurement
are included in this 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 safety, health, and healthenvironmental 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.

3.1 Definitions:
3.1.1 autoclave, n—a pressure-containing vessel used in the HIP process.
3.1.2 hot isostatic pressing (HIP), n—a solid state 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.
3.1.3 inert gas, n—a nonoxidizing gas used for pressurizing a HIP vessel.
4. Ordering Information
4.1 The authorization or requirement for hot isostatic pressing (HIP) shall be agreed upon between purchaser and supplier and
must be documented.
