What is ASTM A615?
What is 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.
What is ASTM 60?
Grade 60: This rebar grade offers enhanced yield strength of at least 60 thousand pounds per square inch (kpsi) under normal conditions.
What is Grade 60 rebar used for?
Grade 60 rebar offers a minimum yield strength of 60,000 pounds per square inch, or 420 megapascals on the metric grading scale. These characteristics make grade 60 rebar particularly well-suited for medium- to heavy-duty concrete reinforcement applications.
What is the chemical composition of ASTM A615?

What is the tensile strength of ASTM A615?
ASTM A615 is a Specification for Deformed and Plain Carbon Steel Bars for Concrete Reinforcement Category Tensile Strength Grade 60 90 ksi (620 MPa) min.
What are the ASTM standards for grade 60 steel?
ASTM A615/A615M Grade 60 standard calls for a minimum 60 Ksi (420MPa) yield strength with no upper limit even on tensile strength. The standard only specifies that phosphorus (P) be no more than 0.06%. The resulting plain carbon steel is expected to have basic ferrite – pearlite microstructure with minimum grain size ASTM 5.
What are the mechanical properties of a615-60 grade steel?
Mechanical Properties of A615-60 Grade Steels: The tensile strength of the A615-60 Grade Steels is expressed in Newton per millimeters and it must be at-least 620 N/mm2 (MPa). The yield strength is minimum 413 N/mm2 (MPa). The minimum percentage ranges for elongation is 9% thicknesses. 180 degree bends on 3.5 diameters.
What does RM stand for in ASTM A615 Grade 80?
Tensile strength (Rm) refers to the maximum stress that ASTM A615 Grade 80 ASTM A615/A615Mbears before breaking. When the steel yields to a certain extent, its resistance to deformation increases again due to the rearrangement of internal grains.
