Description / Abstract:
This specification covers ferritic/austenitic (duplex) stainless
steel forgings for boilers, pressure vessels, and associated
equipment in grades that are also found in Specification
A182/A182M.
The purchaser may specify in the order or contract any
appropriate supplementary requirements that are provided in
Specification A788/A788M.
Unless the order specifies the applicable "M" specification
designation the material shall be furnished to the inchpound
units.
The values stated in either inch-pound or SI (metric) units are
to be regarded separately as standard. Within the text and tables,
the SI units are shown in brackets. 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 specification.
