Reaffirmed 2022

1. Scope

1.1 This standard covers requirements and describes methods of test for high strength deformed stainless steel bars/wires of the following strength grades, for use as concrete reinforcement:

a) SS 500,

b) SS 550,

c) SS 600, and

d) SS 650.

NOTE - The values following the symbol SS indicate the specified minimum 0.2 percent proof stress or yield stress in N/mm².

1.2 This standard applies to solid stainless steel bars/ wires in which the deformations/ribs have been formed by cold working or hot rolling processes.

1.3 This standard applies to hot rolled steel without subsequent heat treatment, or to hot rolled steel subsequently annealed and cold worked. The production process is at the discretion of the manufacturer.

1.4 This standard also applies to reinforcing bars/wires supplied in coil form but the requirements of this standard apply to the straightened product.

1.5 Deformed stainless steel reinforcing bars/wires produced by rerolling finished products such as plates, or from material whose metallurgical history is not known and fully documented is not acceptable in this standard.
