Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement (ASTM A615/A 615M-12)
standard by American Association of State and Highway Transportation Officials, 2015

Category:

Description

This specification covers deformed and plain carbon steel concrete reinforcement bars in cut lengths or coils. Steel bars containing alloy additions, such as with the AISI and SAE series of alloy steels, are permitted if the resulting product meets all the other requirements of this specification.

Bars are of four minimum yield strength levels: namely, 280 MPa [40,000 psi], 420 MPa [60,000 psi], 520 MPa [75,000 psi], and 550 MPa [80,000 psi], designated as Grade 280, Grade 420, Grade 520, and Grade 550, respectively.

Welding of the material in this specification should be approached with caution since no specific provisions have been included to enhance its weldability. When the steel is to be welded, a welding procedure suitable for the chemical composition and intended use or service should be used.

Note: The use of the latest edition of ANSI/AWS D1.4 is recommended for welding reinforcing bars. This document descri bes the proper selection of the filler metals and preheat/interpass temperatures, as well as performance and procedure qualification requirements.

This specification agrees with ASTM A 615/A 615M-12 except for the bend testing procedure, which is referenced to T 285 and Section 9.2.2.
