ASTM A 1000-99

ASTM A 1000-99 specifies requirements for for general applications.

Standard Specification for
Steel Wire, Carbon and Alloy Specialty Spring Quality 1
This standard is issued under the fixed designation A 1000; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers a quality of round and shaped
plain carbon and alloy steel spring wire, uniform in quality and
temper, intended for the manufacture of mechanical springs
that can withstand moderate fatigue stresses over some rela-
tively low number of cycles. The quality level is between the
commercial quality grades of wire such as Specifications
A 401, A 231 and A 229 and the valve spring quality grades
such Specifications as A 230, A 232, A 877 and A 878. It is
similar to the grade TD (referenced in EN 10270-2) intended
for medium fatigue levels, such as required for clutch springs.
This wire shall be either in the annealed and cold-drawn or
oil-tempered condition as specified by purchaser.
1.2 The values stated in either SI units or inch-pound units
are to be regarded separately as standard. Within the text, the
inch-pound units are shown in parentheses. The values stated
in each system are not exact equivalents; therefore, each
system must be used independent of the other.
