Heat Treatment of Parts in a Vacuum
|Publication Date:||1 September 2020|
This specification establishes the requirements and procedures for heat treating parts in vacuum/partial pressure and shall be used as a supplementary document to primary heat treating specifications as applicable.
This process has been used typically for the heat treatment of carbon and alloy steels, tool steels, corrosion-resistant steels, precipitation-harden
Heat treatment as used in this specification includes solution treatment, homogenizing, austenitizing, annealing, normalizing, hardening, tempering, aging, and stress relieving. This specification does not cover processes such as melting, brazing, diffusion bonding, coating, carburizing, or nitriding.
The objective of this process is to produce heat treated parts that have minimal surface contamination and alloy depletion.
Safety - Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
The provisions of this specification revision shall become effective 90 days after publication.
