Title
Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for High Temperature or High Pressure Service and Other Special Purpose Applications
ASTM International
Publication Date:
May 1, 2008
Scope:
This specification2 covers alloy and stainless steel
bolting material for pressure vessels, valves, flanges, and
fittings for high temperature or high pressure service, or other
special purpose applications. The term bolting material as
used in this specification covers bars, bolts, screws, studs, stud
bolts, and wire. Bars and wire shall be hot-wrought. The material
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.
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.
NOTE 1—The committee formulating this specification has included
fifteen 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 material suitable for
use at the lower range of high temperature applications, reference
should be made to Specification A 354.
NOTE 3—For grades of alloy-steel bolting material suitable for
use in low temperature applications, reference should be made to
Specification A 320/A 320M.
Nuts for use with this bolting material are covered in Section
14.
Supplementary Requirements S1 through S10 are provided for use
when additional tests or inspection are desired. These shall apply
only when specified in the purchase order.
This specification is expressed in both inch-pound units and in
SI units. However, unless the order specifies the applicable
M specification designation (SI units), the material shall
be furnished to inch-pound units.
The values stated in either inch-pound units or SI units are to
be regarded separately as standard. The values stated in each
system are not exact equivalents; therefore, each system must be
used independently of the other. Combining values from the two
systems may result in nonconformance with the specification. Within
the text, the SI units are shown in brackets.

applications, see related Specification SA-193 in Section II of
that Code.
