Astm Grade 420 Steel Rebar HRB400 HRB500 6M 12M Hs Code Concrete Iron Steel Rebar
Standard and Performance Comparison
ASTM Grade 420 (corresponding to ASTM A615 Gr60):
Yield Strength: ≥420 MPa (60,000 psi), Tensile Strength ≥620 MPa

Application: US standard, suitable for high-strength structures such as bridges and high-rise buildings

HRB400/HRB500 (China GB standard):
Yield Strength: HRB400 ≥400 MPa, HRB500 ≥500 MPa

Differences: HRB500 is stronger, but has stricter cold bending process requirements (bending core diameter must be ≥5d, compared to 3d for HRB400).
