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.
WebIn the United States, the size designations of these mild steel bars used to reinforce concrete are set by ASTM International. Rebar is generally supplied in 20- and 60-foot lengths. Most bars are “deformed,” that is, a pattern is rolled onto them which helps the concrete get a grip on the bar. The exact patterns are not specified, but the ... WebThe following is a brief history of the appearance and adoption of the various grades of reinforcing bars in ASTM specifications and ACI 318: Grades 33, 40, and 50 were in common use from the early 1900s through the early 1960s. Grades 60 and 75 reinforcing bars appeared in 1959 with the publication of ASTM A432 and ASTM A431, respectively.
WebRebar grades are set by ASTM. The grade designation is equal to minimal yield strength in kilopounds per square inch (KSI). Common grades are 40, 60, 75, 80, and 100. The nomenclature for the grades represents how much yield the rebar has. For example, grade 60 rebar has a minimum yield strength of 60 KSI, which is equal to 60,000 PSI, whereas ... http://resources.crsi.org/resources/astm-standard-reinforcing-bar-card-in-lb/
