GSO ASTM A193/A193M:2014 Scope
.1 This specification2 covers alloy and stainless steel bolting
for pressure vessels, valves, flanges, and fittings for high
temperature or high pressure service, or other special purpose
applications. See Specification A962/A962M for the definition
of bolting. Bars and wire shall be hot-wrought and may be
further processed by centerless grinding or by cold drawing.
Austenitic stainless steel may be carbide solution treated or
carbide solution treated and strain-hardened. When strain
hardened austenitic steel is ordered, the purchaser should take
special care to ensure that Appendix X1 is thoroughly understood.
1.2 Several grades are covered, including ferritic steels and
austenitic stainless steels designated B5, B8, and so forth.
Selection will depend upon design, service conditions, mechanical
properties, and high temperature characteristics.
1.3 The following referenced general requirements are indispensable
for application of this specification: Specification
A962/A962M.
NOTE 1—The committee formulating this specification has included
several steel types that have been rather extensively used for the present
purpose. Other compositions will be considered for inclusion by the
committee from time to time as the need becomes apparent.
NOTE 2—For grades of alloy-steel bolting suitable for use at the lower
range of high temperature applications, reference should be made to
Specification A354.
NOTE 3—For grades of alloy-steel bolting suitable for use in low
temperature applications, reference should be made to Specification
A320/A320M.
1.4 Nuts for use with bolting are covered in Section 13.
1.5 Supplementary Requirements are provided for use at the
option of the purchaser. The supplementary requirements shall
apply only when specified in the purchase order or contract.
1.6 This specification is expressed in both inch-pound units
and in SI units; however, unless the purchase order or contract
specifies the applicable M specification designation (SI units),
the inch-pound units shall apply.
1.7 The values stated in either SI units or inch-pound units
are to be regarded separately as standard. Within the text, 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 non-conformance with the
standard.
