Astm 615 dealing with steel reinforcement specifications specifies the required yield and tensile strengths (fy and fu respectively) as well as elongations.
If the grade is 60, fy (min)= 420MPa; fu (min) = 630 MPa (fu/fy=1.5).
If the grade is 75, fy(min)=520Mpa;fu (min) = 690 MPa(fu/fy=1.33).
Other non american standards specifies that fu >1.1fy.
Any ideas why the astm has such elevated tensile strengths ?
Thank you.
