Title
Standard Specification for Deformed and Plain Stainless Steel Wire and Welded Wire for Concrete Reinforcement
ASTM International
Publication Date:
Sep 1, 2007
Scope:
This specification covers stainless steel wire and welded wire
reinforcement produced from hot-rolled stainless steel rod. The
stainless steel wire is cold-worked, drawn or rolled, plain
(non-deformed) or deformed or a combination of deformed and plain.
It is used as concrete reinforcement for applications requiring
resistance to corrosion and/or controlled magnetic permeability.
Common wire sizes and dimensions are found in this specification.
Actual wire sizes are not restricted to those shown in the
tables.
Supplement S1 describes high strength wire, which shall be
furnished when specifically ordered. It shall be permissible to
furnish high strength wire in place of regular wire if mutually
agreed to by the purchaser and supplier.
A supplementary requirement (S2) of an optional nature is
provided. It shall apply only when specified by the purchaser. In
order to obtain a corrosion tested or controlled magnetic
permeability product, steel conforming to Supplementary Requirement
S2 should be ordered.
The chemical composition of the steel (stainless grade) shall be
selected for suitability to the application involved by agreement
between the manufacturer and the purchaser. Use Specification A 276
for chemical requirements. The UNS designations are to be included
with the type number and noted in brackets, i.e. austenitic
stainless steels as Type 304 [S30400], 304L [S30403], 316 [S31600],
316L [S31603], 316N [S31651], 316LN [S31653] and duplex stainless
steels, Types 2205 [S32205] and 329 [S32900].
NOTE 1—Only austenitic and duplex stainless steels are usually
recommended for use as reinforcement in concrete because of their
high corrosion resistance. Austenitic stainless steels have good
general corrosion resistance, strength characteristics which can be
improved by cold working, good toughness and ductility properties
at low temperatures, and low magnetic permeability. Duplex
stainless steels have generally a corrosion resistance greater than
that of most austenitic steels and are magnetic. Other stainless
steels with different chemical compositions than the series and
types mentioned above, may be used for less restrictive
applications.
Wire for welded wire reinforcement is generally manufactured at
520 MPa [75 ksi] yield strength level. Other strength levels shall
be by agreement between the purchaser and manufacturer.
NOTE 2—The term used to refer to yield strength levels are the
same as those in ASTM Standards for welded wire reinforcement.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. 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.

this standard.
