31 10 2009 nbsp 0183 32 The C E of ASTM A615 rebar generally falls between 0 6 and 0 7 so preheat is almost always required for welding ASTM A706 is a rebar intended for applications requiring controlled tensile properties i e seismic applications and applications requiring enhanced weldability It is available in only one grade Grade 60 Fy 60 ksi ASTM A496 DBA is the What is ASTM A615 ASTM A706 How do they differ from PNS 49 The American Society for Testing and Materials ASTM has developed various standards agreed upon and adopted internationally by a multitude of industries For deformed bars ASTM A615 Standard Specification for Deformed and Plain Carbon Steel Bars for Concrete Reinforcement and 01 03 2005 nbsp 0183 32 These results indicate that ASTM A706 reinforcing bars are more susceptible to chloride induced corrosion than ASTM A615 reinforcing bars are and reinforced concrete structures containing ASTM A615 should exhibit longer times to first repair than structures reinforced with ASTM A706 bars Based on the material characterization in this program the 28 10 2007 nbsp 0183 32 According to the Standards for A706 and A615 there are two designators for these bars W or S to designate that they meet the criteria for both bars The W represents that both bars meet a dual criteria rather than being weldable Since this designator can be on both A706 and A615 according to your statement these bars are interchangeable but according to the 28 10 2007 nbsp 0183 32 albcwi All rebar specifications listed within the D1 4 98 are weldable and that is why they are listed within the code However not all rebar is weldable I m not going to go through my ASTM stds and type every one that is not but there are quite a few that cannot be welded as noted in the standards According to the Standards for A706 and A615 there are two
