ASTM A615

ASTM A615 covers deformed and plain carbon steel bars for concrete reinforcement.  This specification covers bars and coils in four grades, Grade 40, Grade 60, Grade 75, and Grade 80. The grade designates the yield strength of the material, i.e. Grade 60 has a 60ksi minimum yield.

Weldability

Welding this material should be approached with caution since no specific provisions have been included to enhance weldability. If weldable rebar is required, rebar per ASTM A706 should be considered.

A615 rebar increases the tensile strength of concrete and can be used for both primary and secondary reinforcement. It helps absorb stress and weight and facilitates the more even distribution of the tension caused by the expansion and contraction of concrete when it is exposed to heat and cold, respectively.
