Description / Abstract:
Purpose
This specification establishes the requirements and procedures
for heat treating parts (See 8.4) in a vacuum/partial pressure.
Application
This process has been used typically for the heat treatment of
carbon and alloy steels, tool steels, corrosion-resistant steels,
precipitation-hardening steels, super alloys, titanium, and other
nonferrous alloys, but usage is not limited to such
applications.
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
which are free from surface contamination and alloy depletion. Such
parts may not necessarily have a bright surface.
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.
