Understanding ASTM A706 Grade Reinforcing Bar
ASTM A706 weldable rebar is specifically engineered for certain applications; however, it is important to note that its application is not recommended for complex or meticulously designed components. The rebar possesses some constraints in areas such as moment-curvature behavior and inelastic structural deformations.

What is ASTM A706?
The ASTM A706 standard encompasses deformed and plain low alloy steel bars crafted for concrete reinforcement. This specification features strict mechanical properties and chemical compositions to boost weldability. Under this standard, the bars are available in two grades, Grade 60 and Grade 80, where the grade indicates the yield strength of the steel, with Grade 60 having a minimum yield strength of 60ksi.

Weldability
Moreover, A706 rebar is mandated to maintain a carbon equivalent (CE) that does not exceed 0.55%. The calculation of this is done using the formula:
CE = %C + (%Mn / 6) + (%Cu / 40) + (%Ni / 20) + (%Cr / 10) + (%Mo / 50) + (%V / 10)
Bars produced according to this specification are marked with the letter 'W' to show they are weldable.
