Description / Abstract:
Purpose
This specification specifies the engineering requirements for
heat treatment, by part fabricators (users) or their vendors or
subcontractors, of parts made of cast nickel or cobalt alloys and
of fabricated assemblies in which cast nickel or cobalt alloys are
the primary structural components. It is not intended to provide
requirements for heat treating operations that are a responsibility
of the casting supplier in meeting the requirements of the casting
commodity specification.
Application
Alloys
Detailed heat treating instructions are specified for the
age-hardenable (precipitation-hardenable) and non-age-hardenable
alloys listed in 8.2. However, this specification also may be used
for alloys other than those listed in 8.2 provided that
temperatures, soaking times, and cooling requirements are specified
by the cognizant engineering organization.
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 processes and to take
necessary precautionary measures to ensure the health and safety of
all personnel involved
