dc.description.abstract	The corrosion resistance of 2205 and XM-28 stainless steel bars from two producers and provided by a single supplier was tested in accordance with Annexes A1 and A2 of ASTM 955-12. Three heats of stainless steel were tested: XM-28 stainless steel from producer A, 2205 stainless steel from producer B, and XM-28 stainless steel, also from producer B. The bars from producer A were supplied in two conditions, as cut from the coil and after having been straightened, while the bars supplied by producer B were rolled straight. The XM-28 stainless steel bars satisfied the requirements specified in Annexes A1 and A2 of ASTM 955. The 2205 stainless steel bars did not satisfy the requirements specified in Annexes A1 and A2 of ASTM 955, exhibiting individual corrosion rates greater than 0.50 μm/yr and an average corrosion rate greater than 0.25 μm/yr. The process of straightening coiled stainless steel reinforcement damages the transverse deformations of the bars and can leave deposits, either of which can serve as initiation sites for corrosion.	en_US
