BS 6744:2001 pdf free.Stainless steel bars for the reinforcement of and use in concrete Requirements and test methods.
BS 6744 1 Scope This British Standard specifies requirements and describes methods of test for solid stainless steel bars used for the reinforcement of, and use in, concrete. It covers plain round steel bars in grade 200 and ribbed and plain steel bars in grades 500 and 650.
This Standard applies to bars in which he ribs have been formed by the cold working or hot rolling processes. This Standard also applies to plain bars.
Stainless steel bars produced from material whose metallurgical history is not known and fully documented are excluded from this standard.
