This British Standard specifies requirements and test methods for solid stainless steel bars used for the reinforcement of concrete. It is applicable to ribbed stainless reinforcing steel bars in grade500.
It is applicable to bars in which the ribs have been formed by the cold working or hot rolling processes.
NOTE AnnexA specifies a test method for determining the corrosion resistance of stainless reinforcing steel in chloride contaminated concrete. Informative annexes give guidance on durability (AnnexB), magnetic properties (AnnexC), coefficients of thermal expansion (AnnexD), constitutive relationship (AnnexE), welding (AnnexF), performance at elevated temperatures (AnnexG) and quality assurance (AnnexH).
This British Standard is not applicable to stainless reinforcing steel bars produced from material whose metallurgical history is not known and fully documented.
It is not applicable to other uses of steel in concrete, such as plain bars and grades200MPa and ribbed bars above grade500MPa, which are covered by other standards. This is with the exception of 500MPa bar and 650MPa ribbed bar which are now in an informative annex (AnnexI). The standard is open to other strength grades of ribbed bar on the basis that the designers know that these are outside normal UK practice and, once over 600MPa, outside BSEN1992 (EC2).
